Wales rugby star Louis Rees-Zammit has taken a step closer to realising his long-standing ambition of competing in the NFL by signing a three-year deal with Super Bowl champions the Kansas City Chiefs.

Here the PA news agency examines the key questions around his move.

So Rees-Zammit is now an NFL player?

Not yet – and this is where the hard work really begins. Having impressed on the NFL’s international player pathway (IPP) program, the 23-year-old former Wales wing has secured a place on the Chiefs’ practise squad and must now prove he is worthy of selection for their active 53-man roster ahead of the new season, which begins on September 5. Even if he fails to make the initial cut, rules allow for an international player to be elevated to the active roster three times in a season.

What will be his position?

It is still early days but there are a number of options – running back, wide receiver, a hybrid of the two and kick returner. The last of these offers his best route into the NFL, at least in the early stages. Rule changes for the upcoming season have been designed to increase the number of kick returns and it is here that Rees-Zammit’s instinctive running skills, identification of gaps in the defence and athleticism will find their natural home. Apart from the presence of blockers and having to wear extensive padding, it would be the closest he comes to playing rugby on a gridiron field.

What are the odds of making it?

Even for a player with the physical attributes of Rees-Zammit, it will be incredibly hard to actually break through into the NFL. His speed over 40 yards, footwork and hands are valuable assets, but he is competing against rivals who have grown up playing a sport which is new to him. The instincts honed from gridiron exposure at an early age will be missing, while other aspects such as running routes, learning the playbook, experience of a different size ball and adapting to a whole new sporting culture are also obstacles to be navigated. Successfully swapping codes between rugby league and union is a challenge, never mind adapting to a new game altogether.

Which other rugby union players have made it?

From these shores, none. Christian Wade is the highest-profile example after he was recruited for the Buffalo Bills in 2019, also via the IPP. The electric former Wasps wing made an impressive start by scoring a stunning 70-yard touchdown in a pre-season game but he never made the active roster and returned to rugby union in 2022 by signing for Racing 92. Australian-born Hayden Smith and well-travelled Kenyan Daniel Adongo actually made appearances in the NFL, but only a handful between them. If Rees-Zammit is a success, he will be the first.

What happens if the move does not work out?

Moving to the NFL is a win-win scenario for the former Lions and Gloucester sensation. If he makes an impact for the Chiefs, he will become a superstar in British sport. Should it prove too hard a conversion even for an athlete of his quality, he can return to rugby knowing clubs will be queuing up to sign a finisher who has plundered 14 tries in 32 caps for Wales. And if he sees out his Chiefs contract, he will still only be 26-years-old.

Warren Gatland says he relishes the high-pressure stakes of international sport as Wales strive to avoid a first Guinness Six Nations wooden spoon for 21 years.

Gatland oversaw Six Nations titles triumphs, Grand Slams and two World Cup semi-final appearances during his trophy-laden first stint as Wales head coach from 2007 to 2019.

He returned to the role as Wayne Pivac’s successor ahead of last season’s Six Nations, with Wales finishing fifth on that occasion.

But if Wales fail to beat Principality Stadium visitors Italy on Saturday, then they will prop up the final table, which has not happened since Gatland’s fellow New Zealander Steve Hansen was in charge for the 2003 campaign.

Asked about the pressure, Gatland said: “I love it. You find out about people in weeks like this when you are under a bit of pressure, how you respond to that pressure, who is going to put their hand up, who is going to accept the responsibility.

“You find out so much more about individuals when you are under pressure.

“And that is what international sport and professional sport is all about, whether you are playing for Grand Slams or you are at the other end of the table and fighting for survival and fighting to make sure we get a win on the weekend.

“I am still learning about the game, still asking questions about things that you would do differently and how you would prepare differently.

“If you think you know everything, then you are probably in the wrong thing. Things keep moving on, and it is looking at the game and the changes and trying to stay in front of those changes and being proactive about those sort of things.”

Gatland’s squad rebuilding process is under way, one that was underlined by Test retirements last year of Dan Biggar and Leigh Halfpenny – their fellow cap centurion George North will follow after the Six Nations – Louis Rees-Zammit quitting rugby for a possible American football career, Liam Williams playing in Japan, plus injuries to players like Jac Morgan, Dewi Lake and Taulupe Faletau.

“You tend to go back and look a little bit at history,” Gatland added.

“You can go back as far as 2003, which probably wasn’t the best year for Welsh rugby, but two years later that team won the Grand Slam.

“It does take a bit of time. You can’t coach experience. Players learn from being out in the middle. They make mistakes, but it is how you rectify those mistakes for them to be better the next time.

“We know where we are as a group. This group of players have worked incredibly hard and I can’t question the effort.

“Looking at some of the statistical data in terms of GPS numbers, they are very good. There is no way they are not trying out there.

“Both winning and losing become habits, and we’ve got to break that. We are desperate for a win on Saturday.

“We are desperate to go out there and start well and continue to play well for 80 minutes to show as a group we have been improving.”

North will bow out of the international game following a career that saw him help Wales win four Six Nations titles, including two Grand Slams, and play in four World Cups.

The 31-year-old back, who will play for French club Provence next season, has scored 47 tries for Wales – a figure only bettered by Shane Williams – and he is his country’s third most-capped player behind Alun Wyn Jones and Gethin Jenkins.

Gatland added: “He was probably thinking to himself when was the right time (to retire) from a physical point of view.

“We would have loved for him to still be involved, but the conversation with him was that he didn’t want to continue playing for the next couple of years and then potentially leave us in a bit of a hole 12 months out from a World Cup.

“I completely understood his decision with him going to France and taking the family with him.

“It is not completely a surprise to me because we had already had a couple of conversations. We would have loved to have had a player of his ability still to be involved, but at some stage everyone calls time.”

Gloucester have signed former Wasps and England winger Christian Wade – who quit rugby in 2018 to join the NFL’s International Player Pathway – just weeks after losing ex-Wales star Louis Rees-Zammit to the same programme.

The 32-year-old will join from French club Racing 92 ahead of the 2024/25 season and will help fill the void left by Rees-Zammit’s shock move to the US.

Wade was drafted to the Buffalo Bills in 2019 but never played a competitive NFL match and returned to rugby in 2022.

“I’m excited to be returning to the Premiership next season and for a great club like Gloucester,” Wade said.

“After speaking with George (Skivington), I believe in his vision and ambition for the team and I can’t wait to play my part in that.

“I have fond memories of playing at Kingsholm in Wasps colours so I’m looking forward to getting out there in Cherry & White next season.”

Wade played just one Test for England but was selected for the British and Irish Lions’ 2013 tour of Australia.

Head coach Skivington said: “It’s been clear since he returned from America that he has come back in even better shape and still has that sixth sense for the try line that he had before he left.

“We’ve got a pretty exciting stock of back three players here, but it’s hugely pleasing to add someone of Christian’s experience to that group.”

New Ireland star Joe McCarthy has been taking inspiration from American football but has no plans to follow former Wales wing Louis Rees-Zammit in chasing an NFL career.

Leinster lock McCarthy has been one of the standout performers of the opening two rounds of the Guinness Six Nations and was named man of the match on his championship debut against France.

The powerful 22-year-old’s eye-catching display in a 38-17 win over Les Bleus came just over a fortnight after 23-year-old Rees-Zammit stunned rugby union by quitting to pursue a dream in the United States.

New York-born McCarthy, who tuned in with international team-mates to watch Sunday’s Super Bowl as the Kansas City Chiefs defeated the San Francisco 49ers, said: “I love the defensive side of the game, probably like it more than the attack sometimes.

“They say defence wins championships, so it is good.

“I love getting off the line, I love pressuring teams, love getting them ‘man and ball,’ getting in at rucks. I like watching the defensive players in NFL, like seeing the stuff they do.

“At the moment I like Maxx Crosby from the (Las Vegas) Raiders. I liked JJ Watt (former Houston Texans and Arizona Cardinals defensive end) when he played. He is a beat, or was, he is retired now.

“I don’t think I’ll be changing over to the NFL any time soon. I’ll stick with the rugby.”

McCarthy retained his second-row spot for Sunday afternoon’s 36-0 victory over Italy in Dublin as defending Grand Slam champions Ireland backed up their statement success in Marseille.

Following his first Test cap against Australia in the autumn of 2022, he missed last year’s Six Nations due to injury before becoming the youngest member of Andy Farrell’s World Cup squad.

McCarthy admits his elevation at international level has brought increased scrutiny.

“There is way more attention in the Six Nations, you can feel it, much more than club games,” he said.

“It is good, you are getting a lot of nice mentions; you’re trying to block it out and just go back to the process.

“I felt I was ready to go at that stage (in the 2023 Six Nations) but an ankle injury kept me out for a few months. That happens.

“It’s great to get an opportunity now and I am looking forward to it.”

Ireland return to action at home to Wales on February 24 before taking on England and Scotland next month.

Finn Russell insists Wales’ inexperience does not make Scotland’s chances of ending a 22-year wait to win in Cardiff any easier.

Scotland have not won at the Principality Stadium since 2002, losing 11 successive games that comprise nine Six Nations contests, a World Cup warm-up fixture and an autumn Test.

But Wales have hit been hit by a long list of injuries and big-name retirements, while British and Irish Lions wing Louis Rees-Zammit has departed to try and launch a career in American football.

Scotland have arrived in Cardiff in the unusual position of being bookmakers’ favourites for this Guinness Six Nations Championship opener.

But Russell said: “With the Welsh side being slightly different to previous years I think people would see Scotland are favourites.

“I don’t view it like that. We’ve not won here in 22 years, so it shows it’s not an easy place for us to come and win.

“We’ve got a more experienced team, but that doesn’t always count on the day.

“They’ve got very exciting players who will be playing with freedom and that’s part of the joys of having a more youthful side.

“We’re more experienced and we have to lean on that.

“But we’ve got to be careful we don’t overthink the game because it’s a very dangerous team in front of us.

“The atmosphere is one of the best in the world and when the Welsh boys put that red jersey on it’s different to when they are at their clubs.

“It’s a massive challenge for us to win here. We’ve got a few new faces and a few points to prove after a disappointing World Cup, both sides have.”

The Principality Stadium roof will be closed for Saturday’s clash following a U-turn by the visitors.

Under Six Nations regulations, the roof is only closed if both teams agree to it.

Scotland had originally wanted the roof open despite a match-day forecast of persistent light rain.

But Scotland have now reversed that decision with heavier rain forecast and Wales have accepted their request.

Russell said: “For me personally it doesn’t change too much. I was at Racing for five years and they’ve got an indoor stadium. So I’m pretty used to it.

“I think the weather conditions changed over the week, so that’s why the roof is now closed.

“It will get slightly greasy inside with the humidity, but both teams are under the same conditions. It will make for an exciting and fast free-flowing game of rugby.”

Ryan Elias has praised Wales’ Six Nations newcomers and their impact on a squad preparing for Saturday’s tournament opener against Scotland in Cardiff.

Head coach Warren Gatland’s 34-strong group contains just 18 players who were involved in a World Cup campaign that ended only last autumn.

The list of absentees reads like a Welsh rugby who’s who, headlined by players such as Louis Rees-Zammit, Liam Williams, Dan Biggar, Gareth Anscombe, Tomas Francis, Dewi Lake, Jac Morgan and Taulupe Faletau.

Wales have a new skipper – their youngest since 1968 – in 21-year-old Exeter lock Dafydd Jenkins, while Cardiff quartet Cam Winnett, Evan Lloyd, Alex Mann and Mackenzie Martin are among five uncapped players.

It represents a considerable reset on the World Cup road to Australia 2027, but experienced campaigner Elias has been enthused by preparations for Scotland’s Principality Stadium visit.

“There are a lot of young, new faces and they bring a lot of energy to the sessions. They want to learn,” Wales hooker Elias said.

“To be honest with you, it was a bit odd in the first day or two.

“You are so used to seeing the old boys and experienced heads that have been there for years. I remember watching them growing up, people like Dan Biggar, who have been stalwarts for the country.

“Other boys get the chance to – and have to – step up. It is very competitive in training.

“There is a competitive and physical edge. These young lads are sharp, so you have to be on the ball.

“People might not be giving us much of a chance because there have been so many changes, but we are just concentrating on ourselves to put a performance in we can be proud of.”

Wales face successive trips to Twickenham and Dublin after hosting Scotland, which underlines the importance of a first game where recent history strongly favours Warren Gatland’s team.

Scotland have suffered 11 successive defeats in Cardiff, comprising nine Six Nations encounters, a World Cup warm-up game and an autumn Test.

And if Wales can continue that trend it would make an immediate statement not only to their rivals, but also the bookmakers predicting a fifth-place finish with only Italy below them.

Wales assistant coach Neil Jenkins said: “We always believe we can prove ourselves.

“I think most people have written us off already, there is no doubting that. It is not something we tend to worry about.

“It is momentum isn’t it, the Six Nations? I always say with us that we generally get better as the tournament goes on, so the first two games are always massive for us.

“There are quite a few new players involved in this group, and it will be the first time for them in terms of experiencing a Six Nations game.

“It is a settled Scotland side and I am sure they will be fancying their chances, but we’ve just got to focus on ourselves.”

Gloucester boss George Skivington believes that star wing Louis Rees-Zammit’s move to American football is not a “reflection on rugby”.

Rees-Zammit has rocked the rugby world by quitting a sport which brought him 32 Wales caps and a starring role for the British and Irish Lions on their 2021 tour of South Africa.

Wales and Gloucester, though, must now prepare for life without their prolific try-scorer as he heads to the United States, where the NFL’s International Player Pathway awaits him in his quest to forge a new career.

Skivington, though, does not think the sport losing such a box-office figure will start alarm bells ringing.

“I don’t think there are many people who have actually left the sport, really,” he said.

“This happens very rarely – Christian Wade would be the last time someone tried to move in this direction.

“I don’t think it is anything to do with rugby, his (Rees-Zammit’s) decision. It is just something he has always wanted to do.

“I don’t think it is a reflection on rugby at all, I think it is one person’s dream and the opportunity is there.

“I don’t foresee many rugby players going in that direction as a result of it. If it doesn’t work out, he will be back in the game, but I don’t think it is any reflection on rugby itself.”

Skivington confirmed that Gloucester would have discussions with Rees-Zammit, who made his Premiership debut for them as an 18-year-old, if things do not work out in the US.

In the meantime, though, he must plot the remainder of Gloucester’s season without a player whose dazzling try-scoring ability won worldwide admirers.

“We would talk to ‘Zam’ if things fall through, but his mindset is that he won’t be coming back and I think he has to have that mindset to go and do what he is going to try and do,” Skivington added.

“If it all changes, we will see where we are at.

“We would always welcome him back. If he comes back to rugby of course there will be conversations but his mindset as of Monday was very much that he is moving on from rugby and he is going to rip into American football.

“He desperately wants to go and do it and we are not going to stand in the way of someone with what is a pretty unique opportunity.

“He is changing sport. If it doesn’t work out, he might come back to rugby, but his mindset is he is leaving rugby for good.

“He is definitely not taking it lightly. He has got a 10-week programme and then hopefully he gets selected and he gets his foot in the door.

“We all hope he makes it, because it will be a great story if he does.”

Wales boss Warren Gatland admits he has “no idea” if Louis Rees-Zammit will play rugby union again following his switch to American football.

While Wales prepare for a Guinness Six Nations opener against Scotland, Rees-Zammit will be concentrating on the NFL’s International Player Pathway in the hope of forging a gridiron career.

His move to the United States with immediate effect has left Wales and his club Gloucester without a box-office wing, whose try-scoring ability thrilled crowds on domestic, European and international stages.

Rees-Zammit’s rugby union career comes to a halt after winning 32 Wales caps and a World Cup campaign in France when he scored five tries.

Asked if the 22-year-old would come back to rugby one day, Gatland said: “No idea. There aren’t a lot of people who make it in the NFL who haven’t been brought up with the game and played it at a young age.

“There is probably not a lot of difference with rugby league players (trying to play union). Unless you have been brought up playing union, some are able to make it, but very few.

“So it is going to be a challenge for him, but good luck to him.

“We saw Christian Wade (ex-Wasps and England wing) do it, and if you look at rugby league, there was Jarryd Hayne from Australia who had a few games but wasn’t really able to crack it.

“Christian got quite close to doing it. He was a bit older, though. Louis sees it as an opportunity at his age, and if he doesn’t take that chance now it probably won’t come around again.

“We are disappointed to lose a talent like him, but we’ve just got to take that on the chin, move on and focus on the rest of the squad.

“The last thing I can do is dwell on losing him, because the focus has got to be on preparing the squad for the first game.”

Gatland believes that American football will see a player who is “a bit of a freak as an athlete” and someone who is still developing in the sporting arena.

“I thought he was outstanding in the World Cup,” Gatland added. “The pleasing thing for me was that he hardly missed a training session and he was playing well.

“He is probably a bit of a freak as an athlete. He is a freak physically and he gets a chance to challenge himself.

“He has obviously been a big fan (of the NFL) as a youngster and he has got a very high profile away from the game in terms of social media, so this probably helps him enhance that. I am not saying that is a negative at all.”

Another player who will not be part of Wales’ Six Nations squad is 21-year-old Exeter wing Immanuel Feyi-Waboso.

Cardiff-born Feyi-Waboso qualifies for Wales and England, but he is believed to have been involved in a recent England alignment camp organised by head coach Steve Borthwick.

He could now be named in Borthwick’s Six Nations squad, which is announced on Wednesday.

Gatland said: “I didn’t personally speak to him. Mike Forshaw (Wales defence coach) had a conversation with him and he had expressed that he wanted to go down the English route, so good luck to him with that.

“He has definitely got some talent, there is no doubt about it. He is as green as anything.

“He has obviously had an approach from England, and he has decided to take that path.”

Gloucester have released Wales and British and Irish Lions wing Louis Rees-Zammit with immediate effect to “pursue his dream” of a career in American football.

The Gallagher Premiership club made the surprise announcement as Wales head coach Warren Gatland prepared to unveil his squad for the Guinness Six Nations Championship.

Here, the PA news agency looks at some other multi-talented sports people:

Denis Compton (cricket and football)

Compton played 75 Test matches for England, making his debut in 1937 aged 19 and scoring his first century the following year against Don Bradman’s touring Australian side. He had made his Arsenal debut in 1936 and went on to win the league title in 1948 and FA Cup in 1950 with the Gunners, the same year in which he helped Middlesex win the County Championship.

Babe Didrikson Zaharias (athletics, golf)

Zaharias also excelled at basketball and baseball, but initially made her name in track and field, winning two gold medals and one silver in the 1932 Olympics in Los Angeles. Zaharias won the javelin comfortably, took the 80 metres hurdles in a world record time and finished equal first in the high jump before losing the title when her technique was deemed illegal. A latecomer to golf, she won more than 50 titles, including the US Women’s Open three times, and co-founded the LPGA.

Lottie Dod (tennis, golf, archery)

Lottie Dod remains Wimbledon’s youngest women’s singles champion, winning the first of her five titles at just 15 years and 285 days old in 1887. Later turning her attention to golf, she won the 1904 British Ladies Amateur title and four years later won a silver medal in archery at the Olympic Games in London, where her brother Willy claimed gold in the men’s event.

Jim Thorpe (athletics, gridiron, basketball)

The first Native American to win gold for the United States in the Olympics, Thorpe won both the pentathlon and decathlon in Stockholm in 2012. He lost his titles after it emerged he had previously been paid for playing semi-professional baseball, but they were eventually reinstated by the International Olympic Committee. Thorpe played six seasons in major league baseball and for six NFL teams, as well as enjoying a less-well documented spell in professional basketball.

Victoria Pendleton (cycling and horse racing)

Two-time Olympic champion track cyclist Victoria Pendleton announced in March 2015 that she had set her sights on riding in the following year’s Cheltenham Festival. She made her competitive debut in August 2015 and won her first race, on March 2, 2016, on 5-4 favourite Pacha Du Polder at Wincanton. Pendleton then achieved her stated aim of riding in the Foxhunter Chase at Cheltenham and finished fifth, describing the result as “probably the greatest achievement of my life”.

Wales won their Rugby World Cup group and maintained an unbeaten march to the quarter-finals after beating Georgia 43-19 at Stade de la Beaujoire.

Warren Gatland’s team needed one point to finish top of Pool C after securing a last-eight place almost two weeks ago by defeating Australia in record-breaking fashion.

And they accomplished it on the same ground that 16 years ago Fiji condemned them to a World Cup pool-stage exit.

Wing Louis Rees-Zammit scored three tries, while there were also touchdowns for prop Tomas Francis, full-back Liam Williams and centre George North.

Wales ensured there would be no repeat of Georgia’s shock 13-12 success in Cardiff during the 2022 autumn Tests as they overcame fly-half Gareth Anscombe’s withdrawal just 45 minutes before kick-off due to a groin injury.

Anscombe’s late replacement Sam Costelow kicked five conversions and a penalty, although Georgia fought back to 24-19 adrift at one point through tries from Merab Sharikadze, Vano Karkadze and Davit Niniashvili, with Luka Matkava kicking two conversions.

A protracted mass brawl late in the game that spilled over the touchline and involved replacements from both sides saw Niniashvili and Wales substitute Taine Basham yellow-carded.

Wales were home and dry by this stage, although there was more injury concern when number eight Taulupe Faletau went off nursing what appeared to be a wrist problem.

Costelow mixed his running and kicking game well in the early stages, but Wales could get no change out of a well-organised Georgia defence.

There were plenty of errors in perfect playing conditions from both sides, but Wales broke the deadlock after 16 minutes.

A powerful lineout drive put Georgia on the back-foot, before Tomos Williams’ short inside pass resulted in Francis going over for a try that Costelow converted.

Wales had settled into a rhythm, and they struck from another attacking lineout just seven minutes later.

Lock Will Rowlands secured quality possession and, when the ball was moved wide Liam Williams finished impressively. Costelow’s conversion made it 14-0.

A Costelow penalty then opened up a 17-point advantage, and Wales appeared to be well on their way to a fourth successive pool victory.

Georgia regrouped as the first-half drew to a close, and Sharikadze claimed a try that Matkava converted following a sustained spell of pressure.

It was a warning for Wales that they could not switch off as they took a 17-7 lead into the interval.

Georgia began the second period on the front foot, but a midfield fumble saw North find Rees-Zammit, and the Gloucester speedster cruised clear from 60 metres out to claim his third try of the tournament.

Costelow converted, and it was exactly what Wales required after Georgia had threatened a fightback before the break.

Gatland changed the entire front row after 50 minutes, with Nicky Smith, Elliot Dee and Henry Thomas all joining the action.

And while Wales were comfortably ahead, Georgia kept searching for attacking opportunities in their final game of the competition after defeats against Australia and Fiji and a draw with Portugal.

Their resilience was then rewarded with 20 minutes left when replacement hooker Karkadze went over and Matkava converted.

And Georgia immediately conjured a third try, this time from Niniashvili, making it 24-18 and giving Wales plenty to be concerned about.

Gatland’s team were in danger of unravelling, but just when they needed it, Rees-Zammit applied a brilliant finish for his second try which Costelow converted, making it 31-19.

Biggar joined the action deep into the final quarter, and when Rees-Zammit claimed his hat-trick try, Wales were home before North’s try – and Wales’ sixth – completed the scoring, with Japan or Argentina now awaiting as their quarter-final opponents.

Louis Rees-Zammit has underlined Wales’ “game by game mentality” as they target a second successive Rugby World Cup victory that would strengthen their quarter-final ambitions.

Wales, fresh from a thrilling bonus-point victory over Fiji, tackle Pool C minnows Portugal on Saturday.

A showdown with Australia follows eight days later in Lyon, then Georgia in Nantes as Wales chase a fourth last-eight appearance on the bounce.

“We got the win (against Fiji), which was the main thing, but there is a lot to improve,” Rees-Zammit said.

“We’ve got Portugal next and we know they have got great backs, so it’s going to be a tough game.

“We have got a game by game mentality, and that is our focus. You can’t slip up.

“We respect Portugal. We know they have got some great backs, so we are going to have to train hard this week and get the job done.”

Wales head coach Warren Gatland has made 13 changes to the starting line-up, with only wing Rees-Zammit and number eight Taulupe Faletau remaining from last weekend.

Co-captain Dewi Lake leads Wales after recovering from a knee injury, while scrum-half Tomos Williams wins his 50th cap and there are first World Cup starts for the likes of centre Mason Grady, plus Exeter locks Dafydd Jenkins and lock Christ Tshiunza.

Lake suffered a knee problem during Wales’ World Cup warm-up game against England, but he now returns to pack down alongside front-row colleagues Nicky Smith and Dillon Lewis, and fly-half Gareth Anscombe is also back after injury.

Grady, meanwhile, is partnered in midfield by Johnny Williams, Leigh Halfpenny wins his 101st cap at full-back and another experienced campaigner – flanker Dan Lydiate – also features.

At the age of 34 years, eight months and 26 days, Halfpenny will become the oldest back to play a World Cup game for Wales, surpassing Shane Williams, who was a month younger against Australia in Auckland 12 years ago.

Prop Henry Thomas is the only player in Wales’ 33-strong World Cup squad who will not have started or been named on the bench across the first two games.

Wales’ bonus-point success against Fiji has set them up for a repeat performance against Portugal, who are the Pool C minnows.

They are at their first World Cup since 2007, although their pre-tournament form has been reasonable, including a 46-20 victory over the United States.

Gatland said: “We’ve made a few changes this week given the six-day turnaround.

“This is an opportunity now for this matchday 23. I have said before, but there is some great competition within the squad, which is what we want to see.

“There is a chance now for this group to go out on Saturday and to put down their own marker in the tournament.

“We’ve done a thorough debrief of last week’s game and know the areas we need to improve.

“We have a clear plan of how we want to play on Saturday, and it is about going out there and executing that as we have prepared.

“Portugal are a skilful side and will be raring to go this weekend in their first match of the tournament. We are excited to get back out there.”
