The NBA's hottest young scorer got the best of the reigning MVP on Monday as Ja Morant and the Memphis Grizzlies defeated Nikola Jokic's Denver Nuggets 106-97. 

Morant had 26 points, eight assists and seven rebounds for the Grizzlies, who bounced back from an ugly home loss to the Miami Heat on Saturday. 

The 22-year-old Morant is averaging 28.3 points per game, second only to Stephen Curry of the Golden State Warriors (28.7), while shooting 52.4 per cent from the field. 

Jokic played a team-high 33 minutes and finished with 23 points, seven rebounds, seven assists and four blocked shots. 

The Nuggets superstar has shown no ill effects from the knee contusion that forced him out of a game against the Utah Jazz last week in the second quarter. 

The teams meet again in Memphis on Wednesday. 

Short-handed 76ers top Trail Blazers

Joel Embiid missed the game with a planned rest day and Tobias Harris sat out due to health and safety protocols, but the Philadelphia 76ers still managed to defeat the Portland Trail Blazers 113-103 behind 23 points from Seth Curry and 21 off the bench from Georges Niang. Embiid's replacement, Andre Drummond, added 14 points and 15 rebounds for the 76ers as Damian Lillard and CJ McCollum combined to make just 15 of 40 shots from the field, including five of 17 from three-point range, for Portland. 

After making just one of nine shots from the field in the first half, Paul George hit 10 of 15 in the second to finish with 32 points and lead the Los Angeles Clippers past the Oklahoma City Thunder 99-94. Shai Gilgeous-Alexander had 28 for OKC. 

The Chicago Bulls outscored the Boston Celtics 39-11 in the fourth quarter to rally for a 128-114 road victory. DeMar DeRozan had a spectacular shooting game, making 15 of 20 from the field to lead the Bulls with 37 points while Zach LaVine added 26. 

OG Anunoby had 36 points as the Toronto Raptors handed the New York Knicks their second loss of the season, 113-104 at Madison Square Garden. Gary Trent Jr. added 26 for Toronto, while RJ Barrett led New York with 27 points.

Beal, Wizards suffer second loss

Bradley Beal made only three of 11 shots from three-point range and the Washington starting lineup attempted just five free throws as the Wizards suffered their second defeat of the season, 118-111 to the Atlanta Hawks. 

NBA champions the Milwaukee Bucks suffered consecutive defeats after being upstaged by the San Antonio Spurs 102-93.

Giannis Antetokounmpo posted a double-double of 28 points and 13 rebounds, but the Bucks still suffered back-to-back losses on Saturday.

The Spurs (2-4) trumped the Bucks (3-3) on the road in Milwaukee thanks to point guard Dejounte Murray, who scored 16 of his 23 points in the final period.

Murray entered the contest having put up 44 points, 22 rebounds and 23 assists over his previous two games – the only Spurs player in the last 30 seasons to have had at least 40 points, 20 rebounds and 20 assists over a two-game span, according to Stats Perform.

"Obviously, it's a good win against the NBA champions," Spurs head coach Gregg Popovich said after the Bucks were again without Jrue Holiday due to an ankle injury. "They were missing a pretty big piece tonight but it happens to all of us."

76ers gain some revenge as Heat sizzle

Facing the Atlanta Hawks for the first time since being surprisingly eliminated in last season's Eastern Conference semi-finals, the Philadelphia 76ers routed their rivals 122-94. Tobias Harris fuelled the 76ers with 22 points and 11 rebounds, joining Joel Embiid as the only 76ers players this season with 20-10 games.

The high-flying Miami Heat finished one short of setting a new franchise record after sinking 21 three-pointers in their 129-103 victory at the Memphis Grizzlies. Jimmy Butler led the way with 27 points.

Reigning MVP Nikola Jokic starred with 26 points and 19 rebounds as the Denver Nuggets outlasted the Minnesota Timberwolves 93-91.

Double-doubles from Deandre Ayton (17 points and 12 rebounds) and Chris Paul (16 points and 10 assists) helped last season's NBA Finals runners-up the Phoenix Suns beat the Cleveland Cavaliers 101-92.

Jazz taste defeat

The Utah Jazz were the last unbeaten team remaining having opened their season 4-0, until the new-look Chicago Bulls spoiled the party with a 107-99 win.

The Brooklyn Nets' stuttering start to the season continued with their third defeat in five games as they went down 106-93 at home to the Miami Heat.

Jimmy Butler starred for the Heat with a double-double with 17 points and 14 rebounds as well as seven assists and four steals as Miami improved their record to 3-1.

Bam Adebayo stole the show in the final quarter as the Nets threatened to overtake them, landing three big dunks to finish with 24 points and nine rebounds.

James Harden had some bright moments but only managed 14 points with seven rebounds and seven assists, while Kevin Durant had 25 points and 11 rebounds.

All three Nets defeats this season have been by double-digit margins as they continue to miss Kyrie Irving who is absent due to his vaccination status.

Giannis hits 40 in Bucks defeat

Giannis Antetokounmpo scored 40 points but it was not enough as the Milwaukee Bucks suffered their second loss in their title defence 113-108 to the Minnesota Timberwolves.

Antetokounmpo had 40 along with 16 rebounds and seven assists, while all five Timberwolves starters contributed strongly led by D'Angelo Russell (29 points, five rebounds and six assists) and Anthony Edwards (25 points, seven rebounds and three assists).

Harrison Barnes (22 points, nine rebounds and four assists) drained a turnaround triple on the buzzer to clinch the Sacramento Kings a 110-107 win over last season's the Phoenix Suns who had closed a 13-point fourth-quarter deficit late in the game, led by Devin Booker (31 points, six rebounds and eight assists).

The Cleveland Cavaliers added another impressive scalp to their list this season as they downed the Los Angeles Clippers 92-79 with Collin Sexton scoring 26 points.

Westbrook turnovers as Lakers lose

Russell Westbrook got his first Los Angeles Lakers triple-double but he also had 10 turnovers in their 123-115 loss to the Oklahoma City Thunder, with LeBron James absent due to an ankle injury.

LaMelo Ball struggled with only seven points, shooting three-from-14 from the field and only one-from-five beyond the arc as the Charlotte Hornets won 120-111 over the Orlando Magic.

Khris Middleton's three-point radar was off in the Bucks loss to the Timberwolves, shooting one-from-eight and contributing only 16 points, leaving Antetokounmpo with too much to do.

Giannis Antetokounmpo came close to a triple-double as reigning NBA champions the Milwaukee Bucks took down the Indiana Pacers 119-109 on Monday.

Antetokounmpo finished the game with 30 points, 10 rebounds and nine assists, as well as two blocks and a steal to fuel the Bucks.

Bucks team-mate Khris Middleton provided good scoring support with 27 points, five rebounds and seven assists, including a remarkable three-pointer on the first-quarter buzzer.

Milwaukee pulled away throughout the game, leading by 15 points at the final change, having no issues in Jrue Holiday (ankle) and Brook Lopez's (back) absence.

While the Bucks improved to 3-1, the Pacers slipped to a 1-3 record despite Domantas Sabonis' 21 points, 13 rebounds and five assists.

Bulls maintain perfect start

The Chicago Bulls improved to 4-0 for the first time since 1996-97 thanks to a 111-108 victory against the Toronto Raptors. The Bulls led by 10 points with less than three minutes remaining before Fred VanVleet (15 points and a career-high 17 assists) missed a three-point attempt on the buzzer to send it to overtime.

Jayson Tatum posted 41 points, including six three-pointers, with seven rebounds and eight assists as the Boston Celtics outlasted the Charlotte Hornets 140-129 after overtime. The Celtics closed the extra period with a 14-0 run to storm to victory.

Paul George had a career-high eight steals along with 16 points as the Los Angeles Clippers won 116-86 against the Portland Trail Blazers. Luke Kennard added 23 points.

Jonas Valanciunas put up 22 points and a career-high 23 points as the New Orleans Pelicans snapped a season-opening three-game skid by topping the Minnesota Timberwolves 107-98.

Harden's radar still off

The Brooklyn Nets improved their record to 2-2 with a 104-90 win over the Washington Wizards although James Harden's shooting radar was off. The former MVP finished five of 17 from the field, including going at 12.5 per cent from beyond the arc for his 14 points.

Damian Lillard continues to struggle for the Blazers this season. The All-Star finished four-of-15 shooting against the Clippers, while he missed all eight of his three-point attempts. Lillard has made two of 24 three-pointers this season (8.3 per cent). He is shooting 34 per cent overall.

The Los Angeles Lakers claimed their first win of the season after outlasting Ja Morant and the Memphis Grizzlies 121-118 in the NBA on Sunday.

LeBron James and the Lakers had lost back-to-back games to open the 2021-22 campaign but finally had something to celebrate at home to the Grizzlies.

Anthony Davis posted 22 points and eight rebounds, while team-mate James finished with 19 points, six rebounds and six assists for the Lakers (1-2).

But it was Lakers veteran Carmelo Anthony who led the way with 28 points (on 10-of-15 shooting) from the bench.

Anthony passed Moses Malone for ninth place on the all-time NBA leading scorers list.

Morant excelled with 40 points and 10 assists, but it was not enough for the Grizzlies (2-1), who lost for the first time.

Curry brothers star as Steph makes history

Stephen Curry was at it again to lead the Golden State Warriors to their first 3-0 start to a season since 2015 after a 119-107 victory against the Sacramento Kings. The two-time MVP put up 27 points, 10 assists, seven rebounds and three steals to fuel the unbeaten Warriors. With his fifth assist, Curry became the first player in franchise history to dish out 5,000 career assists.

The Philadelphia 76ers topped the rebuilding Oklahoma City Thunder 115-103. Seth Curry maintained his red-hot form, going seven-of-10 from three-point range for a team-high 28 points. Curry was six of seven from beyond the arc for 23 points in the opening quarter – a new career-high for a single period. He is the fourth 76ers player with at least 20 points in a quarter since 2010, joining Joel Embiid (four times), Jodie Meeks and Lou Williams. Embiid had 22 points, nine rebounds and six assists against the Thunder.

Jalen Green enjoyed a breakout game, despite the Houston Rockets going down 107-97 to the Boston Celtics. Green became the first rookie in Rockets history with 30-plus points and eight three-pointers in a game after finishing with 30 points – including eight threes, four rebounds and three assists.

The Charlotte Hornets are off to their first 3-0 start to the season thanks to a 111-95 win over the Brooklyn Nets behind Miles Bridges' 32 points. Kevin Durant led the Nets with 38 points in Brooklyn.

Harden struggles from the floor in Nets loss

James Harden was far from his best against Hornets, going just six-of-16 shooting from the field for 15 points in 33 minutes, while he also finished with eight turnovers.

Evan Fournier was three-of-11 shooting from the field – making just two of seven three-pointers – as the New York Knicks were stunned 110-104 by the Orlando Magic.

The Phoenix Suns soared to a 115-105 victory as LeBron James and the Los Angeles Lakers were condemned to back-to-back defeats to start the 2021-22 NBA season.

Chris Paul fuelled the Suns with 23 points and 14 rebounds in Los Angeles, where the Lakers were no match for last season's NBA Finals participants and fell to 0-2.

Paul became the first player in NBA history with 20,000 points and 10,000 assists.

Devin Booker (22 points) and Mikal Bridges (21 points) also impressed for the Suns, while double-doubles from Anthony Davis (22 points and 14 rebounds) and Russell Westbrook (15 points and 11 rebounds) were not enough for the Lakers.

James finished with 25 points in front of the likes of Floyd Mayweather Jr. and Justin Bieber at Staples Center.

The Lakers' woes were compounded by a row between team-mates Davis and Dwight Howard on the bench during the second quarter as the pair had to be separated.

Durant's Nets spoil 76ers' opener

The Philadelphia 76ers looked in control and on track for victory but they were upstaged 114-109 by Eastern Conference rivals the Brooklyn Nets. Kevin Durant posted a triple-double of 29 points, 15 rebounds and 12 assists as the Nets used a 16-1 run to stun the 76ers in their first home game of the season in Philadelphia. James Harden had 20 points, while LaMarcus Aldridge added 23 points off the bench on 10-of-12 shooting. Seth Curry made all four of this three-pointers to finish with 23 points, the same amount as 76ers team-mate Tobias Harris.

Reigning MVP Nikola Jokic showed why he was crowned the league's best player last season, scoring 32 points, collecting 16 rebounds and supplying seven assists in a 102-96 win against the San Antonio Spurs. It was his eighth 30/15/5 game, doubling the rest of the Nuggets franchise history combined.

The Chicago Bulls' new-look team improved to 2-0 thanks to a 128-112 triumph over the New Orleans Pelicans. Lonzo Ball inspired the win behind his triple-double (17 points, 10 assists and 10 rebounds), while Zach LaVine (32 points) and DeMar DeRozan (26 points) also came up big.

The Utah Jazz stayed unbeaten courtesy of dominant displays from All-Star duo Donovan Mitchell (27 points) and Rudy Gobert (17 points and 20 assists) in the 110-101 road win at the Sacramento Kings.

Myles turner joined James, Harden, Durant, DeMarcus Cousins, Vince Carter and Tracy McGrady as the only players in NBA history to score 40 points, 10 rebounds, five three-pointers and three blocks in a game. The Indiana Pacers still lost 135-134 to the Washington Wizards in overtime.

Celtics lose again

The Boston Celtics were booed off the court at half-time and throughout the second half in their 115-83 defeat against the Toronto Raptors. Jaylen Brown was three-for-13 shooting for nine points and five turnovers, while Marcus Smart ended the game scoreless on 0-for-six shooting in 29 minutes as the Celtics fell to 0-2.

The Philadelphia 76ers put aside the Ben Simmons drama for 48 minutes as the championship-chasing team opened their NBA season with a 117-97 win at the New Orleans Pelicans.

Simmons was nowhere to be seen in New Orleans after the disgruntled All-Star – demanding a trade – was suspended on Tuesday for "conduct detrimental to the team" following reports he was ejected from practice by head coach Doc Rivers.

The 76ers – last season's Eastern Conference top seeds – played without Simmons on Wednesday and made light work of the Zion Williamson-less Pelicans behind Joel Embiid (22 points), Furkan Korkmaz (22 points), Tobias Harris (20 points and 12 rebounds) and new starting point guard Tyrese Maxey (20 points, seven rebounds and five) for their first season-opening road win since 2004.

Korkmaz sizzled in the fourth quarter, scoring 18 points on four-for-four shooting from three-point range – the most points in a quarter by a Sixers bench player since Lou Williams in 2011.

LaMelo leads Hornets rally, Brown has career night

LaMelo Ball put on a show as he helped the Charlotte Hornets come back to pip the Indiana Pacers 123-122. The reigning Rookie of the Year put up 31 points, including seven three-pointers – tying a career high, nine rebounds and seven assists to fuel Charlotte's rally. The Hornets used a 24-0 run – in which Ball scored 12 points – in the third period to the stun the Pacers. Chris Duarte (27 points, six three-pointers and five rebounds) became the first Pacers rookie with 25-plus points, five-plus rebounds and five-plus threes in a game since Jamaal Tinsley in 2002.

A career-high 46 points from Jaylen Brown was not enough as the Boston Celtics lost a wild showdown with the New York Knicks 138-134 after double overtime. Brown's tally was the most points ever by a Celtics player in a season opener. The Knicks withstood the Celtics thanks to Julius Randle (35 points) and debutant Evan Fournier, whose 32 points were the most by a player on debut in franchise history.

Jo Morant had 37 points – the second most on opening night in franchise history, behind only his 44-point haul last season – in the Memphis Grizzlies' 132-121 win at home to the Cleveland Cavaliers. Memphis posted 73 points by half-time – tying the fifth-highest first-half scoring total in their history.

Reigning MVP Nikola Jokic's 27 points and 13 rebounds guided the Denver Nuggets past last season's NBA Finals participants the Phoenix Suns 110-98.

CJ McCollum (34 points), Damian Lillard (20 points and 11 assists) and Jusuf Nurkic (20 points and 14 rebounds) combined for 74 points but the Portland Trail Blazers still lost 124-121 to the Sacramento Kings, who were led by Harrison Barnes' 36 points and eight three-pointers.

Forgettable debut for Rockets rookie

The second pick in the 2021 NBA Draft, Jalen Green endured a baptism of fire midweek. The Houston Rockets rookie finished with nine points on four-of-14 shooting from the field, while he made just one of six three-pointers. His minus-37 was the worst plus-minus by a Rockets rookie in a game in the last 20 seasons – tied for the fourth worst by any Rocket in that span. The Rockets were taken down 124-106 by Minnesota Timberwolves trio Karl-Anthony Towns (30 points and 10 rebounds), Anthony Edwards (29 points) and D'Angelo Russell (22 points).

Back on home court for the first time since February 2020, the Toronto Raptors' long-awaited return to Canada ended in a disappointing 98-83 loss to the Washington Wizards. Toronto missed 19 of their first 21 three-pointers, finishing seven of 34 from beyond the card. They were just 30.9 per cent from the field overall.

Suns star Devin Booker was far from his best against the Nuggets, finishing three-of-15 shooting for 12 points in 30 minutes of action.

Marcus Smart and the Boston Celtics have agreed to a maximum-value four-year contract extension. 

Smart will make $77million in the deal, which begins with the 2022-23 NBA season, according to reports by ESPN and The Athletic. 

Smart posted a video of highlights from his Celtics career on his Instagram page Monday with the comment "Let's go 4 more..."

The 27-year-old has spent his entire seven-year NBA career with the Celtics after they selected him with the sixth overall pick in the 2014 draft. 

He averaged a career-best 13.1 points and 5.7 assists per game last season.

Smart is set to make $14.3m next season, the last in his existing deal. 

After a seventh-place finish in the Eastern Conference was followed by a first-round exit in the playoffs, the Boston Celtics decided it was time for change.

Danny Ainge, the long-time director of basketball operations, is out. Brad Stevens' reign as head coach is over too, though he has switched from orchestrating plays on the sideline to making deals in the front office. His replacement on the bench, Ime Udoka, is an experienced member of supporting casts who finally gets a chance to take on a lead role.

The revamp was not just restricted to team staff, either.

Kemba Walker – seen as a major addition in 2019 – was deemed expendable amid concerns over both his long-term health and salary number. The deal with the Oklahoma City Thunder came at a cost – Boston had to give up their first-round pick in this year's draft as a sweetener – but it may not be the final move for a franchise aiming to regain momentum.

For so long, the Celtics were viewed as a team on the rise. A plethora of burgeoning talents were allowed to develop under the highly rated Stevens, a graduate from the college system who steered them to the Eastern Conference Finals on three occasions between 2017 and 2020.

However, 2020-21 was undoubtedly a step back. A 36-36 record in the regular season, albeit amid the backdrop of a global pandemic, was a surprise. Losing to the Brooklyn Nets in five, however, was not. In fact, the only shock was that they managed to avoid being swept.

So what happens in the next chapter of the Celtics story? Stevens must work out the path for a team that, after playing the long game, has quickly been left behind by its rivals

Boston's double act offers hope

Capitalising on a plethora of draft picks stockpiled over time, the Celtics had sculpted a roster that appeared a step away from moving onto the next level. Major moves were made to try and tip the balance: Kyrie Irving appeared the perfect marriage only for the relationship to flame out, while Gordon Hayward endured a hugely unfortunate start and never completely recovered.

Walker has gone now too, leaving Jayson Tatum and Jaylen Brown as the two fundamental pillars in place for Boston to build around.

Brown finished with a career-high 24.7 points per game at the end of the regular season, a figure aided by shooting 39.7 per cent from deep when averaging 7.1 three-pointers an outing. He attempted more shots in general, with his 19.2 field goals up from 15.6 in the previous campaign. There was also an upturn in assists as well.

However, a wrist injury meant he missed the series against the Nets. Tatum fought a lone hand, including a 50-point performance in Game 3. He became the third Celtic to reach a half-century in a regulation playoff game, joining a select group that also includes John Havlicek and Sam Jones.

Yet that stunning performance merely delayed the inevitable. In putting together a big three, the Nets had jumped the queue in the East. Boston were one of only two teams to have a pair of players finish in the top 20 for points per game in the regular season. The other? Brooklyn, of course.

Tatum averaged an impressive 26.8 points per 75 possessions to continue on an upward curve. Kevin Durant described the third overall pick in the 2017 draft as a "tough, tough cover" after trying to keep him quiet during the first-round matchup. Like Brown, the 23-year-old showed his all-round capabilities by setting career-high averages for points, rebounds and assists.

His usage rate of 30.8 per cent for every 75 possessions was both a sign of his growing status and also a by-product of an ever-changing cast around him. The Celtics used 37 different line-ups – only three teams topped that figure – as injuries and the added wrinkle of the NBA's COVID-19 protocols left Stevens consistently shuffling the deck on a nightly basis.

However, the absences should not paper over the cracks: Brown and Tatum - whose absence from an All-NBA team cost him $33million in his rookie extension – need help.

Moving on from Walker

Boston hoped Walker would be a multi-dimensional scoring guard who could also facilitate for others. The issue was he did not play nearly enough to merit holding on to that ideal any longer.

Walker was restricted to 43 appearances in the regular season, during which he averaged 19.3 points per game – his lowest total since 2014-15. The team was marginally better with him on the court – they scored at 113.2 points per 100 possessions, compared to 109.6 without – though played at a slightly higher pace when the former Charlotte Hornet was absent.

Taking into consideration the likelihood of the four-time All-Star utilising his player option for the 2022-23 season, there was over $73m left on his deal. Boston did get something in return from the Thunder, as a familiar face returned for a second spell (more on that later).

Walker's departure provides some cap relief, of course, but it also leaves a sizable hole in the roster. Marcus Smart appears the in-house option to start at point guard, yet he is heading into a contract year and is still yet to demonstrate how he can be relied upon for consistent offensive production.

His 14.2 points per 75 possessions ranked him 222nd in the league, although a player with a reputation for being a pest to opposing teams posted a defensive rating of 112.8, the highest of his NBA career. As he heads into his eighth season, Smart is a solid contributor capable of making plays without the ball, yet also someone opposing teams do not fear having possession in crunch time.

The same may well be said for Al Horford, even if the Celtics are not quite getting the same player who said farewell to Boston in 2019.

You can call me, Al

Life in Philadelphia did not pan out for Horford following his move in free agency two years ago, with him stuck as the odd man out in a crowded front court where Joel Embiid rules the roost. His time in Oklahoma was short-lived, but now he is back in familiar surroundings.

The 14-year veteran returns having become a more frequent three-point shooter since his first stint – his average of 5.4 attempts in 20 games for the Thunder was a career high, a stark contrast to the player who tried 18 shots from beyond the arc across his first six years in the league.

His playmaking abilities will help lighten the load on Brown and Tatum, while his experience should be invaluable to promising big Robert Williams, whose effective field goal percentage of 72.1 left him behind only DeAndre Jordan in the entire NBA.

Williams also showed he can be a presence on defense, with only five players averaging more blocked shots per game. The third-year center is a low usage, high-value finisher when close to the rim who is primed to take on a starting role.

In general, however, Boston's defensive numbers suffered a dip. Having ranked second in the category in 2019-20, giving up 107.3 points per outing, they fell outside the top 10 this term, their points against number finishing up at 111.2

The Celtics also have a decision to make over Evan Fournier, the trade-deadline addition who is now a free agent. Outside shooting is a must in the league, and the Frenchman was successful with 46.3 per cent of his three-point attempts in the regular season following his arrival from the Orlando Magic.

Last year's first-round selection Payton Pritchard, who shot 46.7 per cent when averaging 2.5 catch-and-shoot three-point attempts, showed signs of promise, but Boston still needs more shooting depth.

Verdict: Evolution

The revolution may have already occurred in Boston. After over 600 games as the head coach, Stevens wasted no time in making an impact following his change of roles.

However, a full re-shaping of the team would require trading away one of the core pieces he has worked so closely with over recent years. Smart, who makes just over $14m on an expiring deal, appears the most trade-friendly asset: the Celtics know the clock is ticking.

Whether Smart sticks around or not, Boston needs more to aid their dynamic duo in Brown and Tatum. The cap situation suggests dipping a toe into the free agency waters, rather than diving right in. There is no point pinning too much faith on the draft process for help either, as their first-round selection is now sitting in the Thunder's treasure chest of picks.

Stevens will survey the landscape and acknowledge standing still is a risk. Brooklyn have their big three, Giannis Antetokounmpo is ensconced in the East with Milwaukee and the Atlanta Hawks have suddenly found their wings to make a run to the Conference Finals.

His final year saw Boston average 1.18 points per possession, behind only the Sacramento Kings, while their effective field goal percentage of 63.3 ranked fourth. There is much to like about this group, yet also a feeling that standing pat is a risk with few potential rewards.

If there is a shortcut to potentially becoming a title candidate, it could be in the form of a frustrated superstar ripe for picking off in a blockbuster trade. That, however, would require a change of mindset when it comes to how they have gone about team building in recent years.

Moving Walker was a fine start, but Stevens the GM has to get creative if Boston are to get back involved in the title race again, rather than just making up the playoff numbers.

The Boston Celtics have reportedly agreed to trade Kemba Walker and a 2021 first-round draft pick to the Oklahoma City Thunder in exchange for former favourite Al Horford.

Walker arrived in Boston in 2019 in a sign-and-trade deal with the Charlotte Hornets that would see the point guard paid a mammoth $140.8million over four years.

The Celtics made that move after losing Kyrie Irving and Horford in free agency.

Horford got a four-year, $97m contract with the Philadelphia 76ers but was traded to the Thunder 17 months later.

Friday's agreement ends miserable stays for both Walker and Horford on their respective teams, while Boston also receive 21-year-old center Moses Brown.

The trade, reported by ESPN's Adrian Wojnarowski, sees Walker, this year's 16th overall pick and a 2025 second-round selection sent to Oklahoma City.

In return, the Celtics get Horford, Brown and a 2023 second-round pick in Brad Stevens' first trade since leaving his role as head coach to become president of basketball operations.

The move crucially allows Boston to get off Walker's contract, which still has $73.7m owed. Horford's deal has a slightly more palatable $53.5m remaining.

For the Thunder, who have already traded the majority of their assets for picks, it means they will have three selections in the first round of this year's draft.

Walker started all 82 games in his final year in Charlotte, contributing 25.6 points per game.

However, in Boston, he dealt with repeated knee injuries, scoring 20.4 points in his first season and 19.3 in his second, which concluded with a 4-1 playoff defeat to the Brooklyn Nets. Walker played three games and averaged 12.7 points.

Horford dropped from 13.6 points and 1.3 blocks on the Celtics to 11.9 and 0.9 on the 76ers.

He did improve after joining Oklahoma City but was then sat for the final two months of the season as the team tanked, handing greater opportunities to fellow big man Brown.

Brown averaged 8.6 points and 8.9 rebounds in 21.4 minutes per game in his only season with the Thunder. He ended the year with a career-high 24 points against the Los Angeles Clippers.

Danny Ainge has announced he is retiring as president of basketball operations for the Boston Celtics, with head coach Brad Stevens promoted to the role.

Ainge is the only person to win NBA championships as both a player and general manager with the Celtics, who confirmed his departure on Wednesday.

The 62-year-old was at the helm of Boston's last title-winning team, back in 2008, and hired Stevens from Butler University to replace Doc Rivers.

However, after a tough season for the Celtics came to an end with a 4-1 series defeat to the Brooklyn Nets in the first round of the playoffs, Ainge has decided to leave his post.

Stevens, who has been the coach for the past eight seasons, will move up to take over from Ainge in the front office, meaning he will oversee hiring his own replacement to lead the team on the bench.

"Helping guide this organisation has been the thrill of a lifetime, and having worked side-by-side with him since he's been here, I know we couldn't be in better hands than with Brad guiding the team going forward," said Ainge in a statement released by the Celtics.

"I'm grateful to ownership, all of my Celtics colleagues, and the best fans in basketball for being part of the journey."

During Ainge's 18-year stint managing the Celtics, Boston made 15 playoff appearances and reached the Eastern Conference Finals seven times.

Their championship triumph in 2008 was one of two trips to the NBA Finals, while it was their first title since 1986. Since that successful season, Boston have won more playoff games than any other NBA franchise.

The Phoenix Suns moved 3-2 ahead in their NBA first round playoffs series against the Los Angeles Lakers with a 115-85 victory but star guard Chris Paul went down after re-injuring his shoulder.

Devin Booker top scored for the Suns with 30 points, seven rebounds and five assists as the Suns move within one win of knocking out the reigning champions.

The Suns, however, will be sweating on Paul's fitness ahead of Game 6 after going down clutching his sore right shoulder, having played 23 minutes, with nine points and six assists.

Phoenix blew the game open with a remarkable 32-10 second quarter, opening up a 32-point half-time lead which the Lakers, who were without Anthony Davis, never threatened in the second half.

LeBron James top scored with 24 points including six three-pointers along with five rebounds and seven assists, while Andre Drummond had seven points and 13 rebounds.

The series returns to Los Angeles for Game 6, before the final match in Arizona if required.

Nugs win in double over-time, Nets progress

Nikola Jokic and Damian Lillard traded blows as the Denver Nuggets edged the Portland Trail Blazers 147-140 in a double over-time thriller.

Jokic finished with 38 points, 11 rebounds and nine assists, while Michael Porter Jr had 26 points, including a clutch late three-pointer along with 12 rebounds and three assists.

Lillard remarkably scored 55 points for the defeated Blazers, along with six rebounds and 10 assists, although he may regret passing to CJ McCollum with nine seconds left at 143-140 down. McCollum mis-controlled and stepped out of play, forcing the decisive turnover.

In a back-and-forth encounter, McCollum had earlier drained a three-pointer to send the game into over-time.

The Brooklyn Nets finished the job in their first round series against the Boston Celtics with James Harden starring in a 123-109 win which completed a 4-1 victory.

Harden produced a triple-double, scoring 34 points with 10 rebounds and 10 assists for the Nets.

Kyrie Irving added 25 points, while Kevin Durant contributed 24, including four three-pointers shooting at 66 per cent from beyond the arc.

The Nets will next face the Milwaukee Bucks in the Eastern Conference semifinals.

Wayward Tatum's radar off

Jayson Tatum was a lone hand for the Celtics, managing 32 points, although he shot poorly, albeit regularly under intense heat, at 12-from-27 from the field and 36.4 per cent from beyond the arc.

History-making haul in losing cause

Lillard's 55 points came in a losing cause, making history as the third most in a defeat in NBA playoffs history behind Michael Jordan's 63 against the Celtics in 1986 and Donovan Mitchell's 57 against the Nuggets in 2020. He also had a record 12 threes.

Hawks at Knicks

The New York Knicks will look to stay alive as their first round playoffs series returns to Madison Square Garden against the Atlanta Hawks trailing 3-1.

Boston Celtics pair Kemba Walker and Rob Williams have both been ruled out of Game 5 on Tuesday against the Brooklyn Nets with their NBA first round playoffs series on the line.

The Nets lead 3-1, having won 141-126 on Sunday in Game 4 over the Celtics who were without Walker (knee) and Williams (ankle).

Point guard Walker had played in Friday's 125-119 Game 3 win but is battling bone bruising in his left knee and coach Brad Stevens confirmed he would not take his place on Tuesday.

Bigman Williams only managed six minutes in Game 3 due to a sprained left ankle.

Boston are already without forward Jaylen Brown for the rest of the season due to a wrist injury, leaving a heavy burden on star Jayson Tatum.

Brooklyn can wrap up the series on Tuesday with victory and were aided by their 'big three' firing in Game 4.

Kevin Durant scored 42 points had four rebounds and five assists, while Kyrie Irving added 39 points and 11 rebounds and James Harden had 23 points and 18 assists in the win.

Kyrie Irving called out "underlying racism" and a "human zoo" environment in the NBA after a Boston Celtics fan threw a water bottle in the direction of the Brooklyn Nets star.

The Nets topped the Celtics 141-126 in Game 4 on Sunday for a commanding 3-1 lead in the Eastern Conference first-round series, but it was overshadowed by another unruly incident.

Ex-Celtics star Irving posted 39 points and 11 rebounds to help fuel the Nets at TD Garden in Boston, where a fan appeared to throw a bottle at the 2016 NBA champion as he left the court.

It comes after former MVP and Washington Wizards guard Russell Westbrook was showered in popcorn during a defeat away to the Philadelphia 76ers in Game 2, while a New York Knicks fan spat on Atlanta Hawks star Trae Young in Game 1.

Following the latest incident in a worrying trend of fan behaviour across the league, Irving – who spent two years with the Celtics from 2017 to 2019 – told reporters: "You're seeing a lot of old ways come up.

"It has been that way in history in terms of entertainment, performers and sports for a long period of time and just underlying racism and just treating people like they're in a human zoo.

"Throwing stuff at people, saying things. There is a certain point where it gets to be too much."

Irving added: "You can see that people just feel very entitled out here. They paid for their tickets -- great, I'm grateful that they're coming in to watch a great performance.

"But we're not at the theatre. We're not throwing tomatoes and other random stuff at the people that are performing."

"Fans got to grow up at some point," Durant said. "I know that being in the house for a year and a half with the pandemic got a lot of people on edge, got a lot of people stressed out, but when you come to these games, you have to realise these men are human.

"We are not animals; we are not in the circus. You coming to the game is not all about you as a fan. So, have some respect for the game. Have some respect for the human beings, and have some respect for yourself. Your mother wouldn't be proud of you throwing water bottles at basketball players or spitting on players or tossing popcorn. So, grow the f*** up, and enjoy the game. It's bigger than you."

On the court, the second-seeded Nets flexed their muscles to move within one win of the Eastern Conference semi-finals.

A game-high 42 points from Durant, and double-doubles from Irving and Harden (23 points and a playoff career-high 18 assists) inspired the Nets.

Durant, Irving and Harden tied the playoffs record for most points scored by three team-mates (104), after John Havlicek (54), Jo Jo White (34), Dave Cowens (16) in 1973 and Dominique Wilkins (50), Randy Wittman (35), Spud Webb (19) in 1986.

Brooklyn duo Durant and Irving also became the first pair of team-mates in NBA history to each score 35-plus points while going 10-for-10 shooting or better from the free-throw line in the same game, according to Stats Perform.

On Irving's performance, Nets head coach Steve Nash said: "It's Kyrie Irving. He didn't have a great game last time out. My money's on him any time after a performance he had. I loved his will, to take some of this adversity and have a great game."

Harden – on what was most satisfying about the victory – added: "Defensively. That's going to be our key every single game. Offensively, that should be the last thing we're worried about because we have so many weapons, so many guys that can get it going.

"Defensively, we have to be engaged, to be locked in possession by possession. I think in Game 3 we weren't consistently locked in on the defensive effort and it showed. Tonight was a lot better and obviously offensively we're wrecking when we come down, the ball moves, and we play with pace.

"Defensively, our effort, and then our rebounding was great too. Ky did an unbelievable job with 11 rebounds. That's elite right there. That's winning basketball."

The star-studded Brooklyn Nets are on the cusp of the Eastern Conference semi-finals after Kevin Durant, Kyrie Irving and James Harden helped take down the Boston Celtics 141-126 in Game 4.

Durant, Irving and Harden led the way to silence the Celtics crowd in Boston, where the second-seeded Nets claimed a commanding 3-1 lead in the opening-round series following a franchise playoff scoring record.

A game-high 42 points from Durant, and double-doubles from Irving (39 points and 11 rebounds) and Harden (23 points and 18 assists) fuelled the Nets at TD Garden on Sunday.

Durant, Irving and Harden tied the playoffs record for most points scored by three team-mates (104), after John Havlicek (54), Jo Jo White (34), Dave Cowens (16) in 1973 and Dominique Wilkins (50), Randy Wittman (35), Spud Webb (19) in 1986.

Brooklyn duo Durant and Irving also became the first pair of team-mates in NBA history to each score 35-plus points while going 10-for-10 shooting or better from the free-throw line in the same game, according to Stats Perform.

After his mammoth 50-point haul in Game 3, Jayson Tatum followed up with 40 points, seven rebounds and five assists but it was not enough for the Celtics, who are facing elimination.

Clippers fightback

After dropping the opening two games, the Los Angeles Clippers are now level with the Dallas Mavericks at 2-2 in the west following their 106-81 rout. Kawhi Leonard's efficient double-double of 29 points (on 11-for-15 shooting) and 10 rebounds inspired the Clippers on the road. Paul George added 20 points as the Clippers became the first team in league history to lose the first two games of a playoff series at home and then win the next two on the road by a combined 35-plus points, per Stats Perform.

The Atlanta Hawks relied on their usual stars to get past the New York Knicks 113-96 and move within one win of the second round of the playoffs. Trae Young had 27 points and John Collins chipped in with 22 of his own as the Hawks earned a 3-1 advantage.

Davis injury caps Lakers loss

The Los Angeles Lakers lost 100-92 to the Phoenix Suns, who levelled the matchup in the west. Anthony Davis' injury headlined the defeat as the Suns capitalised on his second-half absence. Davis suffered a groin injury late in the second quarter and did not return for reigning champions the Lakers in Los Angeles. 

Luka Doncic was cleared to play against the Clippers, despite a neck strain. While he put up 19 points, the Mavs star was just nine-for-24 shooting in Dallas. Doncic also had little support on the court after starters Tim Hardaway Jr. (four points on one-for-eight shooting), Dorian Finney-Smith (eight points on three-for-nine shooting) and Maxi Kleber (0 points on 0-for-three shooting) struggled.

Caruso-LeBron combo

The Lakers lost but Alex Caruso and LeBron James still produced a highlight moment in the second quarter. Caruso lobbed the ball to James off the backboard and the latter finished emphatically. James registered 25 points and 12 rebounds.
