The Arizona Cardinals have removed a controversial "independent study" clause from Kyler Murray's new contract after the quarterback gave an impassioned response to questions about his preparation and work ethic.

NFL.com reported the addendum to the five-year, $230.5million extension earlier this week.

The clause stipulated that the two-time Pro Bowler must watch a minimum of four hours of game film on his own every week during the season over the life of the deal, and the Cardinals could void the contract if Murray did not meet the terms of the agreement.

"After seeing the distraction it created, we removed the addendum from the contract," the Cardinals have now said in a statement. "It was clearly perceived in ways that were never intended.

"Our confidence in Kyler Murray is as high as it's ever been and nothing demonstrates our belief in his ability to lead this team more than the commitment reflected in this contract."

The public revelation of the clause prompted the usually reserved Murray to call an unscheduled press conference on Thursday in which the 2019 number one overall pick lashed out against suggestions he was not properly preparing for his duties.

"I refuse to let my work ethic, my preparation be in question," Murray stated. "I've put in incomprehensible amount of time and blood, sweat and tears and work into what I do.

"To those of you out there who believe that I'd be standing here today in front of you all without having a work ethic and without preparing – I'm honoured that you think that, but it doesn't exist. It's not possible.

"To think that I can accomplish everything that I've accomplished in my career and not be a student of the game and not have that passion, not take this seriously is almost... it's disrespectful and it's almost a joke."

Murray agreed to the extension, which will make him the NFL's second-highest-paid player in terms of average annual salary behind only two-time reigning league MVP Aaron Rodgers, last week. The contract contains $160m in guarantees and will run from 2024 through 2028. 

The 2018 Heisman Trophy winner is coming off his best season in which he finished second in the NFL in completion percentage (69.2) and posted a career-high 100.6 passer rating while helping the Cardinals reach the playoffs for the first time since 2015.

Murray's play dropped off during the second half of the year, however, and he also struggled with a no-touchdown, two-interception performance in the Cardinals' 34-11 loss to the Los Angeles Rams in the opening round of the playoffs. 

Arizona began last season 7-0 but lost five of the 24-year-old's next seven starts, with Murray producing an 86.5 passer rating during that stretch after recording a 116.8 rating over the first seven games.

NBA Hall of Famer Charles Barkley will not be signing a contract with LIV Golf.

The legendary 59-year-old met LIV Golf CEO Greg Norman last week to discuss the prospect of becoming an announcer at events on the controversial breakaway tour.

Barkley on Thursday played in the pro-am at the Trump National Golf Club Bedminster in New Jersey, where the third LIV competition started on Friday.

The 11-time NBA All-Star said he had not been made an offer to work on the Saudi-backed LIV Golf series, but stated: "I'm in a win-win situation. If they offer me something good, that's great. If they don't, I've got a great job at TNT."

Barkley on Friday revealed that he will be remaining loyal to TNT.

He told the New York Post: "I want to thank Greg Norman and LIV for their interest in me. I wish those guys great success and nothing but the best.

"But, in my best interest, and being fair to Turner - because Turner and basketball have given me every single thing in my life - it is best for me to move on and I'm staying with Turner for the rest of my TV career."

Andy Farrell has signed a new deal to remain Ireland head coach until at least August 2025.

Farrell has been talked up as a potential successor to England boss Eddie Jones, but the 47-year-old on Friday put pen to paper on a two-year extension to his Ireland contract.

The Englishman masterminded a historic first Test series win for Ireland over the All Blacks in New Zealand this month, with a 2-1 triumph putting them top of the world rankings.

Farrell replaced Joe Schmidt after the 2019 Rugby World Cup in Japan and will be in charge when Ireland attempt to lift the Webb Ellis Cup for the first time in France next year. 

He said: "I am happy to extend my contract with Irish Rugby for a further two years. As a group we have made it clear that we are building towards the 2023 Rugby World Cup, and we have taken some decent strides in that regard in recent months.

"Ahead of the tour to New Zealand myself and David [Nucifora, Irish Rugby Football Union performance director] looked at the opportunities and challenges facing the national squad after the tournament in France.

"I am excited about continuing to work with the group and with the next generation of Irish international players."

Nucifora said: "Andy is one of the outstanding coaches in world rugby and his work in leading the transition within the national team since the 2019 Rugby World Cup has been exceptional.

"Ireland are currently the number one ranked team in the world, an incredibly tough five match tour of New Zealand was a success on several levels and a Triple Crown was secured in the 2022 Six Nations Championship.

"A coach of Andy's calibre is always going to be in high demand, and we are delighted that he has agreed to extend his contract with the IRFU. 

"This new deal, agreed prior to the Tour of New Zealand, allows us to plan beyond the 2023 Rugby World Cup with the certainty that one of the top coaching talents in the game is spearheading the national programme."

Reigning US Open champion Emma Raducanu believes she needs to cut herself some slack as she aims to improve her consistency on the court.

Having made her breakthrough at last year's Wimbledon championships, Raducanu went on to claim a stunning success at the US Open.

The Briton defeated fellow teenager Leylah Fernandez in straight sets, becoming the first singles qualifier in the Open Era to win a grand slam title.

Yet with the North American swing fast approaching, Raducanu has not yet come close to replicating that form in 2022.

Indeed, since winning the US Open, she has reached just two WTA Tour-level quarter-finals, while she has failed to progress past the second round in any of the three majors.

While acknowledging she needs to add more consistency to her game, the 19-year-old remains relaxed, insisting she is learning to take a step back and enjoy her situation.

"My goal would be towards consistency," she told the Evening Standard. "But equally, I'm going to try and cut myself some slack.

"I'm young and I have achieved something great. I think I should step back and enjoy it.

"I'd say I am too much of a perfectionist. That drives me crazy sometimes. I obviously think it's a great trait, because I don't think I would have had the results I did without that drive and that wanting to be better.

"But it can be really self-destructive at the same time, because you're never happy and you'll always complain or find something wrong."

The Canadian-born star cites her upbringing, and the high standards set by her parents, as crucial to her success.

She added: "They've always had high standards, and told me when things weren't very good, whereas other people might have wanted to encourage me. My parents always told me how it is, and I always had this sense of wanting to prove them wrong.

"Even in primary school, we had a sprint race on sports day and for seven years straight, I won it. I'm undefeated! I really like to win. I love the fight.

"When things get tough, keep getting yourself back up. Keep persevering. Each time you do, it teaches you a lesson and you accumulate experience. Then you can grow a big bank of knowledge that you can tap into."

Raducanu is ranked 10th in the world by the WTA, and this week joined up with Dmitry Tursunov, who will coach her on a trial basis for next week's Citi Open. She split with former mentor Torben Beltz in April.

Luke Donald has taken a dig at Henrik Stenson by declaring he will keep his word and "see it through" if he is named Europe's Ryder Cup captain.

Stenson was last week stripped of the honour of leading Europe against the United States in Rome next year after electing to join LIV Golf.

Donald is reportedly set to replace the Swede, and the Englishman is under the impression he has "a very good chance" of taking the role after holding talks.

"There’s nothing official to report," Donald told Golfweek. "I have been in talks with Guy [Kinnings, Ryder Cup director] at the European Tour. And that's all I know right now.

"I know I have a very good chance, Thomas Bjorn and a couple other guys are under consideration."

Donald, who never finished on a losing side in the four Ryder Cups he played in, says there is no chance he would take up a deal with LIV Golf after agreeing to captain Europe.

"If I got this captaincy, I would live up to my word and see it through," he said. "Let me put it that way. I wouldn't be doing a Henrik."

The 44-year-old Donald is disappointed Stenson defected to join the Saudi-backed LIV Golf series but would "love" to step in for Ryder Cup duty, with the 2016 Open champion out of the picture.

Donald said: "I've certainly had some of my best moments on the golf course in the Ryder Cups. What an amazing honour it is to represent Europe in the Ryder Cup, and I would love to be a captain.

"That would be a huge honour as well. I was surprised that he would put his name forward if his plan was to go to LIV, which, you know, the rumours, and I hate to talk about rumours, but rumours are that he'd been in contact with the rival tours, whatever they were, and he was very interested.

"And I think everyone knew that, the European Tour knew that. They obviously took his word that he wasn't going to do it. We all have to sign a clause or contract saying that we won't have anything to do with (LIV).

"I'm disappointed I guess that he would put his name forward and then go to LIV. I understand certain guys going to LIV, in certain situations in their careers and stuff, that makes sense. But obviously something big to give up."

Donald revealed he has been offered a chance to be part of LIV Golf, but only for a television role.

He said: "Turned that down pretty quickly. A little bit of a slight on my game. I know I haven't played that great, but thanks but no thanks."

Dak Prescott has just one playoff victory in his first six NFL seasons, but he has every intention of making this a memorable year for himself and the Dallas Cowboys. 

"It will be the golden birthday," said Prescott, who turns 29 on Friday. "I plan for this to be the golden year."

Both Prescott and Cowboys coach Mike McCarthy received plenty of criticism after a disappointing 23-17 wild-card loss to the San Francisco 49ers last season. That game ended when Prescott ran downfield with six seconds left on the clock and was unable to spike the ball for one last play.  

That defeat left Prescott with a 1-3 career postseason record and kept Dallas without a Super Bowl title since 1995. 

Prescott has been unable to do what Hall-of-Famers Roger Staubach and Troy Aikman did – lead the Cowboys to a Super Bowl title.  

"I mean obviously knowing the quarterbacks that played specifically for this team, and knowing their legacy, and the ones that we hold at the highest standard are the ones that have Super Bowl rings." Prescott said.

"It starts there for me, trying to fill the shoes of those guys that have come before me and do something for this organisation that hasn’t been done in a long time."

While playoff success has eluded Prescott, he did throw a franchise-record 37 touchdown passes last season and threw for 4,449 yards – the fourth-highest single-season total of any Cowboys quarterback. 

"When you don’t win games, it goes on our shoulders sometimes and that’s okay,' Prescott said. "I’m a guy that will take it whenever.

"Take the good with the bad and just continue to help my team, help all 53 who will participate in the game, but as coach says, it takes more than that.

"It takes the whole unit, the whole organisation. I don’t really worry about where the criticism or blame or any of that goes."

The Cowboys open their season against the Tampa Bay Buccaneers on September 11. 

The Philadelphia Phillies rode a strong starting pitching performance from Zack Wheeler to an 8-4 road victory against the Pittsburgh Pirates on Thursday.

All nine Phillies batters finished with at least one hit – racking up 15 total hits as a team – and it got started in the first inning as Darick Hall made it a 2-0 game with his two-run triple. Nick Castellanos then drove in Hall with a base hit to make it 3-0 in the opening frame.

Wheeler never gave the Pirates a chance to fight back into the contest, holding the home side scoreless until late in the seventh inning. He finished with two earned runs from three hits and three walks, striking out eight.

After Alec Bohm's base hit to make it 4-0 in the second inning, there was a lull in the action until Kyle Schwarber made his presence known in the sixth frame.

With two runners on base, Schwarber connected on his 32nd home run of the season, trailing only Aaron Judge of the New York Yankees.

The Pirates rallied hard in the last inning, scoring five runs from four hits off Jeurys Familia, but there was not much to cheer about up until that point, except for an exciting showing from rookie Cal Mitchell.

Mitchell delivered the only runs for his side in the first eight innings with his towering 414-foot, two-run homer to center-field off Wheeler. He finished three-for-four at the plate, also adding a pair of singles.

Judge does it again for the Yankees

Aaron Judge won the New York Yankees another game off his bat as he blasted the game-winning, walk-off home run to defeat the Kansas City Royals 1-0 at home.

Both sides pitched beautifully, with Royals starter Brady Singer giving up just one hit while striking out 10 in seven innings, while Yankees starter Jameson Taillon struck out eight batters in six scoreless frames.

The home run was Judge's league-leading 39th of the season – seven more than any other player.

Angels blow another Ohtani gem

The Los Angeles Angels wasted another terrific starting pitching performance from two-way All-Star Shohei Ohtani, going down 2-0 at home to the Texas Rangers.

Ohtani struck out 11 batters in six innings, giving up two runs from eight hits in his 10th quality start (meaning at least six innings pitched and three or fewer earned runs) of the season. He now has 145 strikeouts for the season – the sixth most in the majors, and the five players ahead of him have all started at least two more contests.

Only Atlanta Braves rookie Spencer Strider (13.4) has a higher strikeouts-per-nine-innings stat than Ohtani's 13.1.

The top seeds were all victorious in Thursday's action at the Atlanta Open, with John Isner prevailing 7-6 (10-8) 4-6 7-6 (7-3) in an all-American showdown against Ben Shelton to close the day's play.

Isner, 37, relied as he usually does on his trusty serve to get the job done in tiebreakers, winning the match despite not breaking Shelton's serve a single time.

The second seed won 85 per cent (60-of-71) of his successful first serves, while Shelton was similarly stout, converting 83 per cent (50-of-60).

Isner will meet fellow American Jenson Brooksby in the quarter-finals after he came back from an early break to defeat Mackenzie McDonald 6-3 6-4.

The biggest differentiating factor between the two players was Brooksby's effectiveness off his second serve, winning 61 per cent (14-of-23) of those opportunities compared to just 22 per cent (four-of-18) from McDonald.

Fourth seed Alex de Minaur defeated fellow Australian James Duckworth 6-4 6-4 in a competitive match, but De Minaur simply created more chances for himself, with five break point opportunities while Duckworth had two.

De Minaur will play France's Adrian Mannarino after he defeated American Andres Martin 7-5 6-3.

Mannarino's main advantage was with his return game, securing four breaks of serve while dropping his own serve only once.

The Seattle Seahawks have locked up standout wide receiver DK Metcalf with a three-year, $72million contract extension. 

Metcalf’s deal includes a $30m signing bonus – the highest ever for a wide receiver – with $58.2m guaranteed. His yearly salary of $24m ties him with Buffalo’s Stefon Diggs for the sixth-highest total among receivers.  

Metcalf has 216 receptions for 3,170 yards and 29 touchdowns in 49 career games since Seattle selected him with the 64th overall pick in 2019 out of Mississippi. He had 75 catches for 967 yards with a career-high 12 TDs last season. 

The new deal keeps Metcalf with the Seahawks through the 2025 season, with his rookie contract set to expire after this season. He doesn’t turn 25 until December and will be 28 years old when his new deal ends.  

He sat out practice at training camp this week after he missed all three days of mandatory veteran mini-camp in June with an unexcused absence.  

Metcalf and the other Seattle receivers will have a new starting quarterback this season after Russell Wilson was traded to Denver in March. Geno Smith and Drew Lock currently are competing for the starting job.  

Just days after winning the 3M Open, Tony Finau has put together a terrific eight-under 64 to earn the position of joint-leader at the Rocket Mortgage Classic after the first round of play.

Finau came from five shots back on Sunday to lift this past weekend's trophy, and he kept that momentum going with a bogey-free round, birdieing three holes on the front-nine and five down the back.

He finished with the most strokes gained on approach shots (4.20 strokes gained), and was third in strokes gained off the tee (1.65).

Speaking to the media after stepping off the 18th green, Finau acknowledged his rich run of form, and the fact that it was the first round of his career where he had hit all 18 greens in regulation.

"I was riding the high off last week," he said. "I didn’t know that fact before today, that I haven’t hit all 18 greens, so to be able to do that here today is pretty cool."

The only other player at eight under is Canada's Taylor Pendrith, who had nine birdies, and then bogeyed the 18th hole to give up the outright lead.

That pairing is two strokes clear of the chasing field, with England's Matt Wallace and the American group of Michael Thompson, Webb Simpson, Cameron Champ and Lee Hodges all posting 66s.

There is strong international representation in the logjam tied for eighth at five under, including South Korea's Kim Si-woo, Thailand's Kiradech Aphibarnrat, England's Callum Tarren and Sweden's Henrik Norlander.

Australia's Cam Davis is one further back at four under, his compatriots Adam Scott and Jason Day are at three-under, while England's Danny Willett and strong major performer Will Zalatoris are flirting with the cut-line at two under.

Tom Brady's position at the Tampa Bay Buccaneers is an advantage for recruitment, so says general manager Jason Licht.

The veteran quarterback will go around once more this term with the Bucs, after initially announcing his retirement before reversing his decision 40 days later.

And Brady is now helping Licht shape the roster for the upcoming 2022 NFL season, as new head coach Todd Bowles looks to take them to a second Super Bowl in three years following last season's divisional playoff exit.

Speaking ahead of the Bucs' preseason bow against the Miami Dolphins, Licht explained how having Brady on board makes their recruitment business easier, pointing to their acquisition of wide receiver Julio Jones as an example of their similar mindsets.

"I think any GM with an established veteran quarterback has an advantage, but when you have Tom Brady as the greatest, it's even more of an advantage," Licht said in a news conference.

"The entire locker room has the utmost respect for him. If I'm thinking about a player or we are as a staff, I'll give him a call and see if he can help us out and he's always willing to do it.

"We’re usually on the same page with that. We didn't have to kick too many weeds to find out about Julio Jones. We've known about him a while, and Kyle Rudolph was the best tight end that was available.

"But, we're usually on the same page. We have a lot of communication, so does Todd [Bowles] and Tom [Brady] and myself. We talk a lot about players."

Jones is one of the Bucs' key offseason recruits, with the 33-year-old signing on Wednesday after his release from the Tennessee Titans earlier this year, and Brady helped swing the deal.

"It's a scenario we had talked about for a while," Licht added. "I talked periodically to his agent and I know that Tom and Julio had talked.

"It just kind of came to fruition here these last couple of days. We're really excited to have him [and] I know he's super excited to be here. What a mature guy, tough guy, competitive guy, he's just excited to have the chance to win a championship."

Bowles is starting to put the pieces together as he prepares for his first season at the helm following Bruce Arians' departure, though the latter's presence as a consultant has remained invaluable to the team.

"It's great to have him," Licht said of Arians. "He and I obviously have a great relationship. I lean on him for a lot of things. I know Todd does as well and all of our coaches. He's just great to have around."

Carlos Alcaraz got his Croatia Open title defence off to a strong start with a straight-sets victory over Norbert Gombos on Thursday.

The Spaniard, who this week became the second-youngest player to break into the top five of the ATP rankings this century, behind only compatriot Rafael Nadal, saw off Gombos 6-2 6-3 in Umag.

Alcaraz, handed a first-round bye, will now face Facundo Bagnis in the last eight after the Argentinian beat Corentin Moutet 6-3 6-1.

Despite the straightforward nature of his victory over Gombos, the top seed was regularly tested on his own serve.

"It was a really tough match," said Alcaraz, whose triumph in Umag last year marked his first ATP Tour-level title.

"It wasn't as easy as the result seems. Norbert played a really good game and the first round of every tournament is never easy. 

"I had to get used to the conditions. It was tough for me, but at the end I found a way to play better and get the win."

Franco Agamenone also advanced to his first ATP Tour quarter-final with a 3-6 6-1 7-5 comeback over Sebastian Baez, while Marco Cecchinato upset Lorenzo Musetti 6-4 6-3.

At the Austrian Open, Dominic Thiem was eliminated in the quarter-finals of his home tournament by Yannick Hanfmann, the former world number three going down 6-4 3-6 6-4 in a rain-affected contest.

Roberto Bautista Agut prevailed 4-6 7-5 7-5 against Jiri Lehecka in a match lasting nearly three hours. A meeting with fellow Spaniard Albert Ramos-Vinolas, who defeated Pedro Martinez 6-4 6-2, is his reward.
