The Golden State Warriors will approve the four-team trade they agreed to at the deadline, but not before filing a complaint to the NBA about Gary Payton II's injury not being disclosed.

Payton, who was a member of the Warriors' championship-winning team in 2022, left the franchise to sign a free agent deal with the Portland Trail Blazers in the offseason.

He had been battling a number of injuries that kept him out of action until the new year began, but he has since managed 15 appearances since January 2.

Payton's return to action had the Warriors believing his injury problems were behind him, and they were given no indication during negotiations that he was still struggling.

However, their medical examination of him revealed a core muscle injury that the Warriors' medical staff believe will take months to heal.

It meant the Warriors had the ability to void the deal – which was a complicated four-team trade that also sent James Wiseman to the Detroit Pistons, while the Atlanta Hawks received Saddiq Bey – but with the deadline already passed, Golden State would not be able to make any further moves.

That is a crucial point because while the acquisition of Payton was important, the Warriors were just as interested in parting ways with Wiseman. 

The Athletic reported that because of Golden State's status as a luxury tax repeater, the franchise were going to have to pay over $50million for Wiseman's $9m salary this season, and over $80m for his $12m salary in 2023-24.

With how little the former number two draft pick has proven, the Warriors decided his time with the team had run out, and they would prefer the playoff-proven Payton on a cheaper contract.

While they are still going through with the trade, the Warriors filed a complaint to the league about the Trail Blazers providing misleading information about Payton's injury status, prompting the league to launch a review.

It is also being reported that Payton was being pushed by Portland's training staff to play through his injury with the help of pain relief medication.

The Las Vegas Raiders are expected to release quarterback Derek Carr after he informed the team he would not accept a trade to the New Orleans Saints.

Carr's refusal to join the Saints, in a trade deal that had already been agreed between the teams, was reported on Sunday by ESPN and NFL Network.

Reports earlier in the week had detailed Carr's plan to visit the Saints after he was given permission to speak to the team.

However, it is said the contract on offer in New Orleans would require Carr to take a pay cut.

That was not something the QB was willing to do, refusing to waive his no-trade clause, and with only the Saints approaching the Raiders about a trade, the obvious alternative was for the player to be released.

The Raiders would have to cut Carr by Wednesday to avoid paying his full salary in 2023 and instead allow him to enter free agency.

Carr has been with the Raiders since he was selected in the second round of the 2014 NFL Draft, but he said goodbye to fans in an emotional social media post in January.

Las Vegas had hoped for a big season in 2022 but finished third in the AFC West as Carr struggled for form.

Scottie Scheffler reclaimed the world number one ranking after successfully defending his Waste Management Phoenix Open title with a two-stroke victory on Sunday.

Scheffler – after posting rounds of 68, 64 and 68 – closed in style with a six-under 65 to finish at 19-under overall.

He went bogey-free in his final round with four birdies and an eagle, showing his affinity for the TPC Scottsdale course after winning his first PGA Tour event at this tournament last season.

Scheffler's lead was down to only one stroke heading into the famous 16th hole, and while he could only muster a par, that proved to be enough as second-placed Nick Taylor made bogey, and Scheffler extended the lead to three strokes for a comfortable finish with a birdie on 17.

Speaking to CBS after stepping off the final green, Scheffler said he was proud of the way he battled through some average shots.

"I'm just proud of how I fought today," he said. "I didn't have my best stuff, so I grinded it out today. I wasn't hitting it good off the tee, my irons didn't feel sharp, but I played a great round of golf today."

Taylor birdied the 18th to finish alone in second at 17 under for his best result since winning the 2020 AT&T Pebble Beach Pro-Am.

The red-hot Jon Rahm ended up in sole possession of third at 14 under, fellow major champion Justin Thomas finished fourth at 13 under, and former world number one Jason Day continued his return to relevance with a fifth-place result at 12 under.

The highlight of the day came from Rickie Fowler, punctuating his T10 finish with an ace on the par-three seventh hole.

Xavi is adamant there is still more to come from Barcelona after his side battled to a 1-0 win at Villarreal to open up an 11-point lead at the LaLiga summit.

Barcelona continued their perfect record this calendar year with an 11th victory in a row thanks to Pedri's first-half strike at El Madrigal.

The Catalan giants struggled to kill off the contest, with Robert Lewandowski having three attempts saved by Pepe Reina, and that almost came back to haunt them late on.

Samuel Chukwueze found a way past Marc-Andre ter Stegen, but the goal was quickly ruled out for offside as Barca kept a fifth clean sheet in six league games.

Despite now having a double-figures points advantage on Madrid, who play their game in hand at Elche on Wednesday, Xavi is not ruling Los Blancos out of the title race.

"There are many points left to play for," he told Movistar+. "The run of form we are on is extraordinary, but we can still improve certain things.

"Villarreal wanted to have possession today, and they squeezed us. We missed a lot of final passes and, by doing so, we have ended up suffering."

Barcelona have recorded seven wins by a 1-0 scoreline in 21 LaLiga games this season, equalling their highest total in a full season in the history of the competition.

They have conceded just seven LaLiga goals all campaign, which is six fewer than any other team across Europe's top five leagues.

"The defensive side of things isn't our main weapon, but it is bringing us results," Xavi said. "The defence starts from Robert [Lewandowski], which is very noticeable.

"We leave here having given no big chances to Villarreal and we leave very happy."

Pedri's goal in the 18th minute was his sixth of the season in the league, with four of those coming in 1-0 victories for Barca.

Indeed, no player has won more points for his team in LaLiga with goals this season than Pedri (10 points, level with Real Betis striker Borja Iglesias).

The Spain international was played through on goal following a quick one-two with Lewandowski, but only after Barcelona turned possession over in midfield.

"The game was like that. We either stole the ball off them or they stole it off us," Xavi added. "It's about taking advantage. I think today's victory came from that aspect."

Barca host Cadiz in their next league match, but first is a Europa League knockout play-off round first leg against Manchester United on Thursday.

Massimiliano Allegri has defended his Juventus players amid their turbulent Serie A season, arguing they deserve greater respect for their performances.

The Bianconeri edged Fiorentina in a 1-0 win on Sunday, with Adrien Rabiot's first-half finish enough to seal the victory in Turin.

The result comes amid a campaign that has seen Juve's top-four hopes torpedoed by a 15-point sanction handed down for financial mismanagement off the field.

Allegri, who was seen rowing with a fan during the closing stages, feels his players have shouldered unfair blame for a decision outside of their control, and backed them afterwards.

"I am disappointed, because while most of the crowd is helping the team, there are a few who decide a player is poor and jeer [us]," he told DAZN.

"Players like Moise Kean, Mattia De Sciglio, Leandro Paredes. They are Juventus players, and we need all of them.

"I don't like people coming to the stadium ready to jeer. That is disrespectful. By all means jeer when we do badly, but not ahead of time."

The sanction handed down against Juve has left them with a limited shot at both silverware and a place in European competition next year.

Allegri however is not giving up on either front, adding: "The Europa League and the Coppa Italia are objectives, along with climbing back up the table.

"We have to take it one game at a time. It is a new experience, it is interesting to go through, and we're sticking together."

Two goals were chalked off throughout the encounter for marginal offside calls by VAR, against Dusan Vlahovic and Gaetano Castrovilli.

In both instances, the pair saw their efforts denied by a matter of millimetres, to which Allegri called for further alterations to the system.

"I think that is the right way to go," he added to Sky Sport Italia. "We can't have goals disallowed for hair being offside. We'd all have to get the same haircut as me!"

The Boston Celtics received terrific performances from Derrick White and Robert Williams III to defeat the visiting Memphis Grizzlies 119-109 on Sunday.

With Celtics All-Star Jaylen Brown out of action due to a broken bone in his face, and Jayson Tatum struggling on his way to a three-of-16 shooting performance, it was up to the role players to step up in what was a playoff-quality matchup.

After his best game of the season on Friday – scoring a season-high 33 points with 10 assists – White followed it up with another terrific showing. He led the Celtics with 23 points on eight-of-20 shooting and a game-high 10 assists.

Meanwhile, Williams – who set a season-high with 16 rebounds on Friday – matched that figure again, including five on the offensive end, while the Grizzlies only grabbed three offensive rebounds as a team. 

Tatum ended up salvaging a respectable stat line of 20 points, seven rebounds, two steals and two blocks, but he was nowhere to be found in a close fourth quarter.

Instead, it was Al Horford providing the game-winning scoring burst, with 11 of his 16 points coming in the final five minutes to repel any late Grizzlies charge.

Ja Morant led the visitors with 25 points (nine-of-18 shooting), seven assists and six rebounds.

With the win, the Celtics improved their league-leading record to 41-16, while the Grizzlies sit second in the Western Conference at 34-22.

VanVleet and Siakam lead Raptors to victory

The combination of Fred VanVleet and Pascal Siakam provided the scoring punch in the Toronto Raptors' 119-118 home win against the Detroit Pistons, but a new addition held things together defensively.

VanVleet led all scorers with 35 points (12-of-26 shooting) and eight assists, while Siakam put together a strong performance with 28 points (10-of-19 shooting), six assists and two blocks.

On the defensive end, it was trade acquisition Jakob Poeltl showing exactly why the Raptors traded a first-round pick for him at the deadline, leading the game in both blocks (three) and steals (two) before fouling out in 25 minutes. Toronto were plus 11 with him on the court, and minus 10 while he was on the bench.

Clyde Edwards-Helaire is inactive for Super Bowl LVII, the Kansas City Chiefs running back unable to make his return from a high ankle sprain.

Edwards-Helaire was activated from injured reserve ahead of Sunday's showpiece at State Farm Stadium, having been sidelined since Week 11 because of the injury.

But the former first-round pick will not feature in Glendale, Arizona, meaning Isiah Pacheco and Jerick McKinnon will shoulder the bulk of the workload in the backfield.

Rookie Pacheco has enjoyed an outstanding season, rushing for 830 yards and five touchdowns.

He has done an excellent job of creating yards even when the opposing defense creates disruption in the backfield. Pacheco has averaged 3.68 yards per carry on runs where there was a disruption, the third most among backs with at least 100 carries.

McKinnon's impact has been primarily been as a receiver, catching nine touchdowns in the regular season.

One player who will return from an ankle injury to play in the Super Bowl is the Eagles' Australian punter Arryn Siposs, who was confirmed as active for the game having been out since December. He will reassume the punting duties from Brett Kern.

Wu Yibing triumphed in an extraordinary final against local hero John Isner at the Dallas Open to become China's first winner of a singles title at ATP tour level in the Open Era.

Isner served 44 aces but still lost, with the 37-year-old going down 6-7 (4-7) 7-6 (7-3) 7-6 (14-12) in a match that saw neither player break serve at any point, climaxing in a marathon tie-break.

Former world number eight Isner was chasing a 17th singles title, and a first at an indoor tournament, and he saw a match point slide by at 6-5 in the second set.

Wu resisted one of the best serves in tennis history and took the match all the way. The first 22 points of the third-set tie-break went with serve, before Wu hit a super backhand winner to interrupt the sequence. Incredibly, Isner won the next rally to bring it back on serve, but the match then got away from him, and a stray forehand from the American gave Wu the title.

Dallas resident Isner, famed for his 11 hours and five minutes win over Nicolas Mahut at Wimbledon in 2010, featuring a 70-68 final set, said of this loss: "That kind of stunk for me."

Wu said: "It's a very tough match today. I'm not even moving when he serves. I made history here for my country. I'm very proud of myself."

Luciano Spalletti praised Napoli's supporters for helping his side lift their levels after they cruised to a 3-0 win over Cremonese in Serie A.

Goals from Khvicha Kvaratskhelia, Victor Osimhen and Eljif Elmas saw the league leaders extend their advantage to 16 points at the summit.

After losing to their rock-bottom visitors in the Coppa Italia last month, the hosts were able to take their revenge at Stadio Diego Armando Maradona.

But it came after something of a loose start, with Spalletti praising encouragement from supporters as key to helping his team focus in the second half.

"Our city, our fans, they care about what we are doing here," he told DAZN. "[They understand] the possibility that we can do important things.

"Everyone could see, perhaps too much, that we weren't as calm as we usually are in the first half. We got a little nervous, and it was more difficult.

"Cremonese played wide and we lost energy having to defend the balls they put into our penalty area. But it was much better in the second half.

"I applauded [the crowd] because that's what they do for our team. Our players are ready to destroy themselves on the pitch for a result."

A 17th goal of the league season for Nigeria international Osimhen saw the attacker further build his lead in the goalscorer charts this term.

Spalletti spoke positively about his player afterwards, and was keen to highlight how the striker is less vocal in his protests on the pitch.

"There are some things that shouldn't interest us on the pitch, which concerns different stuff than what should draw our attention," he added.

"Tonight there was an incident where we could have had a different reaction. Instead, it all remained orderly. The match must be managed as we did."

Jurgen Klopp has reiterated he is "100 per cent committed" to Liverpool and dismissed comparisons to his previous jobs as he tries to turn around a dismal season.

The Reds have been knocked out of both domestic cups and sit 10th in the Premier League ahead of Monday's Merseyside derby against Everton at Anfield.

Klopp's men were beaten 3-0 by Wolves last time out and questions have been asked about his future, but the German does not want to go anywhere and is determined to solve the problems himself.

"I will not and I cannot go," he told reporters. "I have too much responsibility and I want to sort it... if people believe in me then we have to go through this together because then when we come out [of it], we will have great times again.

"Maybe the difficult times are a bit too long already, for me as well... but I don't think about these kind of things. I am here, 100 per cent committed."

The 55-year-old has cut a frustrated figure in recent weeks, having seen his team win just one of their last seven games (D2 L4), and he attempted to explain why he was particularly irksome following the Wolves defeat.

"How I said before, if we win, I feel like I was part of it. If we lose, I feel 100 per cent responsible and I was always in my life like this, and you can imagine how big the responsibility l am feeling at this moment is," he said.

"We will do absolutely everything to get through this and prepare the very positive future again, but I cannot change that we lost the last game the way we lost it. 

"There is one moment I am really emotional and that is immediately after the game and you face me then, but apart from that I am completely clear and can do the job I always did, I am experienced enough to know that you can get through this."

Comparisons have been made to Klopp's time at his two previous clubs, Mainz and Borussia Dortmund, with the German spending seven years at each before moving on.

Currently in his seventh full season at Liverpool, it has been theorised that Klopp is enduring a similar trajectory, but he rejected that notion, saying he did not leave Mainz for the same reasons he left Dortmund, and adding the situation at Liverpool is completely different again.

"When I left Mainz it was a career step," he said. "When I left Dortmund I was really exhausted in that moment, it was a lot and I thought we have to change something, it was time to do something else, [but] neither-nor in this moment, neither-nor. I am completely here.

"I understand that people think: 'look at that, seven years, seven years,' it's nothing to do with it. The situation is difficult for different reasons, but this is not one of them."

Pedri's first-half strike earned Barcelona a 1-0 win at Villarreal and moved the LaLiga leaders 11 points clear at the summit.

With closest challengers Real Madrid away on Club World Cup duty – which they won with victory over Al Hilal in Saturday's final – Barca took full advantage at El Madrigal.

Pedri struck with 18 minutes played after linking up with Robert Lewandowski, who had a couple of attempts saved by Villarreal goalkeeper Pepe Reina.

Villarreal had the ball in the net late on but Samuel Chukwueze's strike was ruled out as Barca opened up a double-figures lead on Madrid, who have a game in hand to play.

Reina denied Lewandowski from a one-on-one inside the first three minutes, but the Poland striker played a big part in Barca's breakthrough goal.

Pedri played a quick one-two with Lewandowski, controlled the return pass when it arrived to him in front of goal and calmly tucked the ball away from Reina.

Lewandowski was again thwarted by Reina when going for goal himself, but Villarreal gave Barca a scare as Jose Luis Morales raced through and fired into the side-netting.

Both sides continued to create the occasional opening, with Raphinha sending an effort across the face of goal and Alex Baena flashing wide from further out at the other end.

Villarreal edged the second period and thought they had levelled through Chukwueze, but Yeremy was flagged for offside as Barca kept a fifth clean sheet in six league games.

Victor Osimhen extended his lead atop the goal charts as he helped Serie A leaders Napoli to a 3-0 win against rock-bottom Cremonese.

The Nigeria international prodded home a close-range finish in the second half to add to Khvicha Kvaratskhelia's earlier effort at Stadio Diego Armando Maradona. Eljif Elmas added a late third, making sure.

For home coach Luciano Spalletti, the three points came with a side order of revenge after his side were knocked out of the Coppa Italia last month by their visitors, and they go 16 points clear for now.

But for Cremonese boss Davide Ballardini, the fight to seal top-flight survival is growing dimmer by each matchday, despite a spirited performance from his team.

Taking to the field in the Valentine's Day strip they debuted against the same opponents in their earlier cup clash, Napoli dominated matters across the first quarter.

It was little surprise when they opened the scoring in the 21st minute, with Kvaratskhelia seizing on a poor clearance to dance his way back into the box for a low finish.

Both teams fluffed further good chances, including a missed header for Osimhen, while the hosts also had a penalty appeal waved away just before the break.

Hirving Lozano went close to adding a second Napoli goal seven minutes into the second half, when he forced Marco Carnesecchi into an acrobatic save.

There was no denying Osimhen in the 65th minute, as he flicked Kim Min-jae's header over the line following a corner kick that was parried by the goalkeeper.

That gave Osimhen a 17th league goal of the season in just his 18th appearance, with his haul putting him five clear of Ademola Lookman and Lautaro Martinez in joint-second.

With a two-goal cushion, Napoli could have cruised to the finish line, but Elmas fired in with just over 10 minutes to go to ensure it would be an even more comfortable conclusion.
