The Portland Trail Blazers have been dealt another injury blow with shooting guard CJ McCollum ruled out for at least four weeks.

McCollum hurt his foot during the victory over the Atlanta Hawks on Saturday and sat out Monday's game against the San Antonio Spurs, which ended in a 125-104 loss for the Trail Blazers that saw them slip to 8-6.

Portland were already without center Jusuf Nurkic due to a right wrist fracture and he has been joined on the sidelines by McCollum.

A statement tweeted by the Trail Blazers read: "Further imaging reveals CJ McCollum with a small hairline fracture to the lateral cuneiform in his left foot and a mid-foot sprain.

"McCollum will wear a walking boot and be re-evaluated in four weeks."

Prior to his injury, McCollum was performing at the highest level of his career. Through 13 games he was averaging 26.7 points and 4.8 made three-pointers per game, both of which would be career highs.

Asked about adjusting to the losses of Nurkic and McCollum after the defeat to the Spurs, All-Star point guard Damian Lillard said: "It's tough. We've had that type of luck over the years, it's always been something.

"But we pride ourselves on be able to adjust to that and keep our stride whatever comes our way. We trust our experience in these situations.

"It's not always going to be perfect. When a guy goes down, or in our case two of our best players go down, the next game might not be the game where it just happens. It might be a game or two or three where you struggle and then it clicks, it might be one game or you might not miss a beat.

"It wasn't the outcome we wanted but we're still going to believe in each other, we're still going to have a high level of accountability and I think next game we're going to be better and we should expect to be better."

LeBron James was frustrated with the performance and the officials as the Los Angeles Lakers suffered a fourth-quarter collapse against the Golden State Warriors.

Defending NBA champions the Lakers went into Monday's home game on a run of five straight wins.

They raced into an early 19-point lead and still led by 14 in the fourth quarter but fell to a surprise 115-113 loss.

The game marked the 284th time in his career James and his team took a double-digit lead into the fourth quarter at home in the regular season and postseason. Per Stats Perform data, it was the first of those in which LeBron's team lost the game in regulation.

It was not what the Lakers needed before starting a seven-game road trip on Thursday against the Milwaukee Bucks.

"I think we just had some tough breaks, some tough calls against us in the second half that slowed our pace down," said James, who finished with 19 points, five rebounds and five assists.

"We couldn't get back into a rhythm.

"Obviously you are frustrated any time you lose, especially when you know you could have played better. We know we can play much better. We can all learn from that and apply it to next game."

James was not happy about being called for travelling, adding: "It is so funny because the very next play Draymond [Green] gets into the lane and slides his foot and it is not called.

"The same official who called me for the travel is right there on the play and told me he didn't travel."

Anthony Davis had 17 points, 17 rebounds and seven assists, while Dennis Schroder topped the team with 25 points, but they fell to 11-4 overall and 4-4 at home this season.

Lakers coach Frank Vogel added: "We got outplayed in the second half. We got hesitant on the offensive end, and a little casual at certain points in the game."

Stephen Curry scored 26 points to inspire another Warriors comeback, as the team improved to 7-6.

Earlier in January the Warriors beat the Lakers' city rivals, the Los Angeles Clippers, despite being 22 behind in the third quarter.

"We kept our composure and the second unit was amazing both halves," Curry said.

"We got some momentum in the second half to give us a chance and carry us down the stretch. It was similar to the Clippers game. We've done it twice now but want to get leads early."

The Warriors play at home against the San Antonio Spurs on Wednesday.

They had lost their past two games against the Denver Nuggets and Indiana Pacers despite a combined 55 points from Curry.

The two-time MVP is averaging 28.2 points per game, on pace for the second-best scoring season of his NBA career.

Nicolai Muller scored a late winner as Western Sydney Wanderers beat Central Coast Mariners 1-0 to move top of the A-League.

The Mariners had won each of their first two matches of the season and would have returned to the top with a point.

Instead it is the Wanderers who sit at the summit on seven points from their first four games after their away victory on Tuesday.

Substitute Muller settled a fiery contest in Gosford with seven minutes remaining.

After Joshua Nisbet had hit the crossbar for the hosts, Muller finished calmly from eight yards when fellow substitute Kwame Yeboah's powerful shot deflected into his path.

The Mariners visit champions Sydney FC on Friday, while the new leaders do not play again until their clash with Newcastle Jets on January 29.

Kevin Durant and James Harden feel experience has proven key in a "seamless" transition to their partnership with the Brooklyn Nets.

The former Oklahoma City Thunder duo combined to impressive effect as the Nets battled to a 125-123 win at home to the Milwaukee Bucks on Monday.

Durant won the game courtesy of a three-pointer with 36 seconds remaining to reach 30 points, while adding nine rebounds and six assists.

Harden followed up his dream debut against the Orlando Magic with 34 points, 12 assists and six rebounds.

It is the first time two team-mates have had at least 30 points in each of their opening two games for a franchise, per ESPN.

"We have been through a lot in this league," Durant said about his link-up with Harden.

"Experienced a lot, and for us to bring it together now and combine what we've learned over this time and try to play great basketball, I think it was pretty seamless for us.

"It was an easy transition, especially with James handling the ball a lot coming in. So we're still trying to find our way, and we've still got room to improve, but it's a solid start."

Harden is yet to practice with the Nets since his blockbuster trade from the Houston Rockets.

"We were young in Oklahoma City," Harden – who impressively followed up his triple-double against the Magic – said when asked about his connection with Durant.

"We are grown men now. We know what we want. We really know the game of basketball now. 

"We are not those young guys that want to run around and just shoot and dunk all day.

"And then for me, I sit back and I know what player Kevin Durant is. He's one of the best players to ever touch a basketball. This is a huge win for us."

With four straight wins moving them to 9-6, the Nets are next in action at the 6-7 Cleveland Cavaliers on Wednesday.

The Nets' other star, Kyrie Irving, is set to return to practice on Tuesday. He missed his seventh straight game against the Bucks, who got 34 points from Giannis Antetokounmpo.

"This is what they do – they wake up, come to the game and they score 30," Antetokounmpo said. 

"If you're not aggressive and you're not locked in against them, they're going to score 50."

James Harden and Kevin Durant guided the Brooklyn Nets past the Milwaukee Bucks, while the Los Angeles Lakers' winning run was ended.

The Nets extended their winning streak to four with a 125-123 victory over the Bucks on Monday.

It was their second win in as many games since Harden joined in a trade from the Houston Rockets last week.

The eight-time All-Star had a double-double of 34 points and 12 assists, while Durant finished with 30 points against the Bucks.

Durant hit a clutch three-pointer with 36.8 seconds remaining to lift the Nets to 9-6.

Bucks star Giannis Antetokounmpo had 34 points, 12 rebounds and seven assists.

After five straight wins, the Lakers went down to the Golden State Warriors 115-113.

Warriors star Stephen Curry had 26 points, while Dennis Schroder top-scored for the Lakers with 25.

LeBron James (19 points) missed a three-pointer on the buzzer for the Lakers, who had Anthony Davis post a double-double of 17 points and 17 rebounds.

Awesome Adebayo, Oladipo makes Rockets debut

Bam Adebayo posted 28 points and 11 rebounds to guide the Miami Heat past the struggling Detroit Pistons 113-107.

Victor Oladipo arrived at the Rockets following Harden's exit, and he had 32 points and nine assists on debut, but it came in a 125-120 loss to the Chicago Bulls.

DeMar DeRozan (20 points and 11 assists) led an even team effort in the San Antonio Spurs' 125-104 victory over the Portland Trail Blazers. DeRozan (20), LaMarcus Aldridge (22), Patty Mills (21) and Rudy Gay (21) became the first group of four Spurs team-mates to each score 20-plus points in a game since 2010.

A double-double from Trae Young (20 points and 13 assists) helped the Atlanta Hawks past the Minnesota Timberwolves 108-97.

Doncic below his best

Luka Doncic described himself as "selfish" despite a triple-double in a Dallas Mavericks loss to the Bulls on Sunday, and he was below his best a day later. He went four-of-11 from the field for just 15 points in 34 minutes in a 116-93 humbling at the hands of the Toronto Raptors.

Clutch KD

Durant hit the crucial three-pointer to lift the Nets to their victory.

Thunder at Nuggets

Victoria Azarenka called for greater understanding from players stuck in hotel quarantine ahead of the Australian Open.

After being exposed to coronavirus on flights, 72 players – including Azarenka – have been forced into a two-week quarantine ahead of the tournament beginning on February 8.

Novak Djokovic reportedly made several requests, which were rejected, of officials for players in quarantine, while Roberto Bautista Agut compared the conditions to prison.

But amid complaints on social media, two-time Australian Open champion Azarenka pleaded for players to be more understanding in a measured statement.

"Dear players, coaches, entourage and Australian community. I would like to take a moment and address some of my colleagues as well as the media around the world," the Belarusian wrote on Twitter.

"This has been a very difficult time for a lot of us that did not expect to end up in the situation we are in today, myself included. To be in a 14-day hard quarantine is very tough to accept in terms of all the work that everyone has been putting in during their off-season – to be prepared for playing our first grand slam of the year. I understand all the frustration and feeling of unfairness that has been coming and it is overwhelming.

"We have a global pandemic, nobody has a clear playbook of how to operate at full capacity and without a glitch, we all have seen it last year. Sometimes things happen and we need to accept, adapt and keep moving.

"I would like to ask all my colleagues for cooperation, understanding and empathy for the local community that has been going through a lot of very demanding restrictions that they did not choose, but were forced to follow.

"I would like to ask to be sensitive as well to the people who have lost their jobs and loved ones during this horrible time for all of us around the world. I would like to ask all of us to have respect for people who work tirelessly to try to make our lives easier.

"I would like to ask the media to please have consciousness on the impact and influence you bring to this situation and to the community. I would like for the people in the community to know and understand that we have it as our top priority to ensure the health [and] safety of all the people.

"Lastly, I would like for us to please try to support each other as much as someone can or is willing to. Things are always easier when you have a compassionate environment and work together."

Victoria endured tough restrictions after a second coronavirus wave last year.

On Tuesday, the state recorded its 13th consecutive day of no locally acquired cases of COVID-19.

Stefano Pioli said Zlatan Ibrahimovic exceeded expectations with his brace in Milan's 2-0 win over Cagliari on Monday.

Ibrahimovic scored a brace as Milan moved three points clear of rivals Inter atop Serie A.

The 39-year-old has found the net in nine successive starts for the first time in his career in Europe's top five leagues as he moved onto 12 Serie A goals in eight games this season.

Milan coach Pioli said Ibrahimovic performed above expectations, with his side closing out a win despite Alexis Saelemaekers' 74th-minute red card.

"Ibrahimovic is a champion in everything he does. Of course, now that he is back, we have more options and qualities," he told a news conference.

"The more choices and strong players we have, the more likely we are to win games.

"He still surprises me, but now I know him so well. We always expect him to give the maximum, and today he exceeded our expectations."

Ibrahimovic had the most shots (five) and shots on target (three) against Cagliari, while no player was involved in more duels (17).

Milan extended their unbeaten run away from home in Serie A to 16 matches, which equals their most in the three-points-per-win era (since 1994-95).

"We are happy with today's performance. It wasn't easy to play on such a difficult pitch like this one, facing an opponent with great qualities," Pioli said.

"We deserved the victory and now we will start focusing on the next important game on Saturday against Atalanta."

Roberto Bautista Agut labelled the quarantining of players ahead of the Australian Open a "complete disaster", comparing it to prison.

After being exposed to coronavirus on flights to Australia, 72 players are in hotel quarantine for two weeks ahead of the tournament starting on February 8.

Players have hit out at the conditions, although tournament director Craig Tiley insisted on Tuesday most were happy to be in Australia.

But world number 13 Bautista Agut slammed the position players had been put in.

Told he looked like he was in prison, the Spaniard told Sport5: "It's the same, it's the same, with Wi-Fi.

"These people have no idea about tennis, about practice courts, has no idea about anything, so it's a complete disaster because of that, because the control of everything.

"It's not Tennis Australia, it's the people from the government."

Victoria on Tuesday recorded its 13th consecutive day of no locally acquired coronavirus cases, with three of the four in hotel quarantine linked to the Australian Open.

Bautista Agut, a 2019 quarter-finalist at Melbourne Park, said two weeks in quarantine would be difficult.

"I did work in the room but it's not the same," he said.

"I was feeling very, very tight and I cannot imagine staying two weeks like this. It's really, really tough."

Australian Open tournament director Craig Tiley defended Novak Djokovic, saying the world number one had provided "suggestions", not demands.

With 72 players forced into quarantine for two weeks after being exposed to coronavirus on flights, Djokovic reportedly made demands regarding their conditions.

Among them, the eight-time Australian Open champion reportedly asked for players to be moved to private houses with tennis courts, with his requests rejected.

But Tiley played down the reports, saying Djokovic had simply made suggestions.

"Novak wrote a note, these weren't demands, these were suggestions," he told Channel 9 on Tuesday.

"But he too is understanding what two weeks of lockdown means."

Tiley also backed the players despite reports and social media posts suggesting they were unhappy about being forced into quarantine.

"Last night we spent quite a bit of time with the playing group going through a number of different items because they've just been here for a few days getting used to this quarantine environment," he said.

"I have to say on that call there were about 500 players and the vast majority are happy to be here, pleased to be here and really getting ready in the next two weeks to be able to get out and play in the lead-in events and then play the Australian Open on February 8.

"I think the reports we're reading and the things we're seeing doesn't represent the entire playing group. For the most part, they've been pretty good."

With the preparations of 72 players so far impacted by quarantine, there have been suggestions the Australian Open be changed to a best-of-three sets format in the men's draw.

But Tiley said he had no plans to make such a drastic change.

"We're a grand slam at the end of the day and right now three out of five sets for the men and two out of three sets for the women is the position we plan on sticking to, starting February 8," he said.

Paris Saint-Germain sporting director Leonardo believes Mauricio Pochettino can help refine the Ligue 1 club's identity.

Thomas Tuchel was sacked as PSG coach in December, with former Tottenham boss Pochettino confirmed as his replacement on January 2.

Leonardo said it was crucial for Pochettino to ensure PSG had their own defining philosophy but acknowledged that would take time.

"I think it's important to assert a style on the pitch, because Paris must have its identity," he told France Football.

"It does not happen in a few weeks but over several years. And I think Pochettino can allow us to refine that in a constant way and in connection with the DNA of the club."

Tuchel led PSG to back-to-back Ligue 1 titles and they reached the Champions League final last year before falling to Bayern Munich.

Leonardo said the decision to sack the German should have come as little surprise to the former Borussia Dortmund coach.

"We knew, and he [Tuchel] knew, that it would be difficult to renew his contract at the end of the season," he said.

"But there, we decided to anticipate a little. We did not change coaches to show off. I don't think it could be a surprise for Tuchel.

"It was not the first time that we discussed the situation together. Maybe he didn't understand me anymore."

PSG are top of the Ligue 1 table ahead of hosting Montpellier on Friday.

Zlatan Ibrahimovic believes Mario Mandzukic will "scare" opponents like he does, with Chelsea's Fikayo Tomori also poised to join Serie A leaders Milan.

Ibrahimovic restored the Rossoneri's three-point lead over rivals Inter at the summit with both goals in Monday's 2-0 win at Cagliari.

And Milan are not resting on a position of strength, with their veteran top scorer under the impression a deal to bring in former Bayern Munich and Juventus forward Mandzukic on a free transfer is already done.

"Mario Mandzukic has signed his contract, he's joining AC Milan," Ibrahimovic told Sky Sport Italia.

"I'm happy we have two that scare our opponents."

Youth is set to join experience, with 23-year-old Chelsea defender Tomori on the verge of a loan switch to San Siro as he seeks regular first-team opportunities.

"We wanted Fikayo Tomori also last summer, he's always been one of our targets," Milan technical director Paolo Maldini said.

"He's perfect for our squad. We're working on the last details."

Ibrahimovic addressed Maldini directly after the game, saying a renewal of his own contract at Milan depended on his former team-mate.

The 39-year-old once again displayed evergreen form on his first league start since the end of November in Serie A, taking his tally to 12 goals in just eight Serie A appearances this term.

"Young people motivate me, they challenge me to see who runs more, I don't give up and show that I can run like them," he said.

“We are doing well, we are almost halfway through the season.

"Now the most difficult games are starting. It will be a very tough schedule, but with Mandzukic, [Monday debutant Soualiho] Meite, I don't know if more will arrive … more players available for the coach, they can help."

Asked whether he believed Milan could end Juventus' long reign as champions of Italy, Ibrahimovic inimitably replied: "I believe in me, in Zlatan."

Zlatan Ibrahimovic returned to Milan's Serie A starting line-up with both goals in a 2-0 win at Cagliari that restored their three-point lead over Inter at the summit.

Antonio Conte's side pulled level with the Rossoneri thanks to their impressive victory over champions Juventus in Sunday's Derby d'Italia.

But Ibrahimovic is inspiring Milan's title bid with a prolific fervour and marked his first league start since November in style.

A seventh-minute penalty and a crisp half-volley early in the second period took the 39-year-old's tally to a remarkable 12 goals in just eight Serie A appearances this term.

Milan finished with 10 men as substitute Alexis Saelemaekers ludicrously collected two bookings within eight minutes of his 66th-minute introduction but fourth-bottom Cagliari could not avert a fifth straight Serie A loss.
