Emma Raducanu has "no idea" if she will be fit for Wimbledon after retiring from her first-round match against Viktorija Golubic at the Nottingham Open on Tuesday. 

Second seed Raducanu conceded the match after 36 minutes having sustained an injury to her left side while down a break at 4-3 in the opening set. 

The 19-year-old is scheduled to appear at Birmingham next week before heading to Wimbledon, where she reached the fourth round last year. 

US Open champion Raducanu, who made her WTA Tour debut in Nottingham last year, is unsure if she will recover in time to feature at the All England Club. 

"I think I pulled something, I am not really sure what exactly happened," Raducanu said. 

"I have just come off court, an absolute freak injury. I don't know what I could have done more about it. That is it. 

"I have no idea [about Wimbledon]. It could have just seized up and gone into spasm and then it is really bad for a few days. I have no idea. I cannot diagnose myself. I will get it checked out." 

Raducanu was the only seed to exit the tournament, with top seed Maria Sakkari overcoming Camila Osorio 6-2 6-3 to advance to a second-round meeting with Rebecca Marino. 

Beatriz Haddad Maia came from a set down to beat Wang Qiang 5-7 6-4 6-3, while Ajla Tomljanovic and Camila Giorgi had comfortable victories against Wang Xinyu and Sonay Kartal respectively. 

Aryna Sabalenka cruised into the second round of the Rosmalen Grass Court Championships by defeating Kateryna Baindl 6-4 6-1. 

Fifth seed Liudmila Samsonova, meanwhile, succumbed to a 6-3 6-4 loss to Ann Li in an hour and 22 minutes. 

There would have been further casualties among the seeds had Tamara Zidansek, Ekaterina Alexandrova and Elise Mertens not fought from a set down to win their opening matches. 

The minimum age ice skaters must be to compete in senior events has been raised from 15 to 17 for the sake of protecting the "physical and mental health" of competitors.

The International Skating Union (ISU) announced the change on Tuesday, almost four months after the sport was in the spotlight for the wrong reasons during the Beijing Winter Olympics.

Russian Kamila Valieva, aged 15 at the time, was provisionally banned during the Games after it came to light that she had tested positive for banned heart medication trimetazidine last December.

That revelation came just before the Russian Olympic Committee were due to be awarded a gold medal for the team event in which she had competed.

Valieva was cleared to go for individual gold, but slipped from first place to miss out on a medal after making a string of mistakes in her decisive final routine.

Rather than consoling a distraught Valieva, her coach, Eteri Tutberidze, instead asked her "why did you stop fighting?" in reference to an initial error on her opening triple axel.

International Olympic Committee (IOC) president Thomas Bach says it was "chilling" to see the way Valieva was treated by her coach.

The ISU has now revealed competitors skaters must be 16 to enter senior events from the 2023-24 season and 17 as of the following season.

Despite some growing pains in his second NFL season, Jalen Hurts helped the Philadelphia Eagles reach the playoffs in his first year as a full-time starter in 2021.

The team is hoping he will take a big step forward entering his third pro season, and so far, coach Nick Sirianni has been impressed with his progress.

"I'm noticing a big difference," he told ESPN's Sal Paolantonio. "What I see is a crisper ball. The accuracy I've been very pleased with. You can just see him taking strides every single day with his accuracy because of the fundamentals he has with his feet and his upper body."

Hurts' focus since Philadelphia’s 2021 season ended with a 31-15 loss to the Tampa Bay Buccaneers in the Wild Card Round has been on his footwork and his throwing mechanics with an emphasis on his timing.

A major advantage for the 23-year-old quarterback this offseason is that he is working with the same offensive system from 2021 – the first time since high school he has used the same playbook in successive seasons.

"That's been very pivotal going into the offseason ... just being decisive out there on the field, knowing pretty much where I'm going to go with the ball based off the look that they give me," Hurts said. "There's a natural maturation there, as I've always talked about."

Hurts led all quarterbacks in rushing yards with 784 and rushing touchdowns with 10 in 2021, but was not one of the more dangerous passing QBs.

He ranked 15th in yards per attempt (7.28), 22nd in passer rating (87.2), 26th in completion percentage (61.3) and was tied with three other QBs for 23rd in TD passes (16). In the golden age of passing, he had just two 300-yard passing games while Philadelphia averaged 200.2 passing yards per game – eighth lowest in the NFL and fewest by a playoff team.

"We want that to come up," Sirianni said in reference to the passing ranking.

The offseason addition of A.J. Brown should help with the Eagles’ passing attack. Brown led the Tennessee Titans last season with 63 catches for 869 yards and five receiving touchdowns and will team with DeVonta Smith, who led Philadelphia with 64 receptions for 916 yards and five TD receptions as a rookie in 2021.

"It's my job to just go out there and play point guard," Hurts said. "Distribute the ball, get the playmakers the ball, and my plays will come."

Tiger Woods will not play at the U.S. Open this month but plans to be at St Andrews for The Open in July.

The 15-time major champion withdrew from the US PGA Championship last month after shooting a nine-over 79 in his third round.

Woods was playing in only his second tournament since suffering serious leg injuries in a car crash in February 2021.

The 46-year-old had made a sensational comeback at The Masters in April, defying the odds to make the cut at Augusta before finishing 47th.

Woods stated ahead of the US PGA Championship at Southern Hills that he felt "a lot stronger" than he did after making an unlikely Masters comeback, but struggled on moving day in the second major of the year.

The legendary American on Tuesday confirmed he will not feature in the U.S. Open, which starts at The Country Club in Brookline, Massachusetts on June 16.

However, he is aiming to tee off in the JP McManus Pro-Am at Adare Manor in County Limerick on July 4-5 and play in the last major of the year in Scotland, which gets under way on July 14.

He tweeted: "I previously informed the USGA that I will not be competing in the @usopengolf as my body needs more time to get stronger for major championship golf.

"I do hope and plan to be ready to play in Ireland at @JPProAm and at @TheOpen next month. I'm excited to get back out there soon!"

Woods outlined his plans amid a storm in the golfing world, with his compatriots Dustin Johnson and Phil Mickelson having resigned from the PGA Tour to play in the Saudi-backed LIV Golf Invitational Series.

Greg Norman, the CEO of LIV Golf, this week told the Washington Post that Woods had turned down a "mind-blowingly enormous" offer to play in the controversial breakaway series.

The new era of Duke basketball continues with the formation of a new front office position to help players enhance their marketing skills in the new college sports world created by NIL (name, image and likeness).

First-year Blue Devils coach Jon Scheyer announced on Tuesday that Rachel Baker is the program's first general manager – a position she will use to assist players in capitalising on strategic partnerships. 

"The state of college basketball is growing and changing at an exponential rate," Scheyer said. "Rachel is a one-of-a-kind talent with unique experience that will provide our players and their families with an unparalleled resource and partner as we navigate new frontiers of college basketball together.

"Through her work in the NBA and at Nike, she brings nearly a decade of expertise in the business of basketball to our staff, as well as her gifts in relationship and community building, leadership development, and experiential marketing. We can't wait to see all she brings to our program in this newly created position." 

A former lacrosse player at La Salle and the daughter of a collegiate basketball coach, Baker spent eight years at Nike and one year in the NBA league office before joining Duke. At Nike, she led their Elite Youth Basketball League, developing partnerships and managing strategic initiatives. During her year with the NBA, Baker directed the marketing and rebranding of the WNBA. 

"I could not be more excited to join Jon Scheyer and the entire Duke Basketball family," said Baker. "We're in the middle of such a transformative moment – not only for Duke, but for the college basketball landscape – and the chance to be part of it is the opportunity of a lifetime.

"Duke Basketball has remained rooted in honoring our storied history while writing the future of the game. I am humbled and honored to join this tradition and can't wait to get started." 

Baker is the latest major change for the Drake program following the retirement of coach Mike Krzyzewski after he had led the team to five NCAA Tournament championships since his hiring in 1980.  

Scheyer, the 34-year-old former Blue Devils star, had been on Coach K’s staff since 2014 and took over for the Hall of Fame coach following his planned retirement in April. 

Baker, who graduated from La Salle in 2012 and holds an executive education certificate in business of entertainment, media and sport from Harvard University, is the daughter of Rod Baker, who coached Tufts from 1983-88 and Cal-Irvine from 1991-97. 

Deebo Samuel is expected to attend the San Francisco 49ers' mandatory minicamp amid a contract saga that has overshadowed their offseason.

Samuel requested a trade from the 49ers back in April and was reportedly refusing to engage with San Francisco in discussions over a long-term extension.

The All-Pro wide receiver was said to be dissatisfied with his role in the 49er offense, which relied on him heavily as both a receiver and a running back in 2021 as San Francisco reached the NFC Championship Game.

However, the Niners stood firm in refusing to trade Samuel, reportedly rejecting offers for the 2019 second-round pick during the first round of the 2022 NFL Draft.

Kyle Shanahan said during a media conference that none of the offers were "even remotely close" to what the Niners would consider the right price for Samuel.

Samuel did not attend the Niners' organised team activities, which are voluntary, but multiple reports said Samuel will avoid any fines for skipping minicamp, which begins on Tuesday, by returning to San Francisco's facility.

He and Shanahan were each in attendance, although sat in different areas of the arena, at Chase Center in San Francisco on Sunday for the Golden State Warriors' NBA Finals clash with the Boston Celtics.

And Samuel's decision to attend minicamp could be seen as a positive step in contract negotiations, with the Niners understandably keen to hold on to him beyond the 2022 season, which marks the final year of his rookie deal.

In addition to making 77 catches for 1,405 yards and six touchdowns – averaging a league-leading 18.2 yards per reception – in 2021, Samuel also carried the ball 59 times for 365 yards and eight touchdowns, breaking Eric Metcalf's record (six) for most rushing touchdowns by a wide receiver in a single season, set in 1989.

Samuel labelled himself a 'wide back' when asked to define his position, and he registered 27 rushing attempts in the playoffs, scoring a rushing touchdown against the Dallas Cowboys and converting a key third down on the ground in the fourth quarter of the win over the Green Bay Packers, before the Niners' Super Bowl hopes were ended by the Los Angeles Rams.

The Niners made moves to potentially placate Samuel's apparent frustration with his role in the draft, selecting running back Tyrion Davis-Price and a wide receiver with the speed to do damage out of the backfield, Danny Gray, in the third round.

General manager John Lynch last week said Samuel would be a part of the Niners this season, and the odds of him being proven right now look to have improved.

Talor Gooch has claimed criticism of LIV Golf stars for sportswashing is not fair, explaining: "I'm not that smart... golf is hard enough."

Gooch has been named as one of 12 team captains for the new Saudi-backed LIV Golf Invitational Series.

The two-time PGA Tour winner will captain Torque GC, with bigger names like Phil Mickelson – leading Hy Flyers GC – and Dustin Johnson – of 4 Aces GC – among his opponents.

All of those to abandon the PGA Tour for the new project have come in for scrutiny given the source of the huge financial backing the breakaway league has.

LIV Golf is being funded by Saudi Arabia's Public Investment Fund (PIF), linking the series to a country with a hugely concerning human rights record.

As with other PIF acquisitions, such as Premier League club Newcastle United, LIV Golf has been highlighted as an example of sportswashing for the Saudi regime.

But this suggestion was put to Gooch on Tuesday, as he faced the media at the event's launch.

"I don't think that's fair," he said. "Also, I'm a golfer. I'm not that smart. I try to hit a golf ball into a small hole. Golf is hard enough.

"I try to worry about golf, and I'm excited about this week."

Gooch has earned $9million over his entire PGA Tour career; a single win at one of these events would fetch almost half of that at $4m. Even the player in last place at each regular season tournament will receive $120,000.

Emma Raducanu lasted only seven games of her first-round match at the Nottingham Open, where she made her WTA Tour debut a year ago.

US Open champion Raducanu was back in Nottingham as she prepares for a second Wimbledon campaign.

The 19-year-old made a name for herself with a run to the fourth round at her home grand slam in 2021, before she sensationally triumphed at Flushing Meadows.

Having seemingly established herself as the next superstar of women's tennis, Raducanu has since not found life quite so straightforward.

"It has been a really tricky 12 months, to be honest," Raducanu told the BBC on Tuesday before her match against Viktorija Golubic. "It hasn't always been easy."

And this was anything but easy for the second seed, who required treatment on an apparent side injury as soon as after the third game.

Raducanu and Golubic had traded breaks before that medical timeout, and the Briton then quickly broke again.

But she continued to encounter problems and dropped serve twice – either side of further medical treatment – before finally retiring 4-3 down.

Raducanu is scheduled to play the Birmingham Classic next week but will first now have to consider her fitness just 20 days out from the start of Wimbledon.

All-time greats often aren't truly appreciated until after they have called time on their career. 

Following speculation he could hang up the cleats in the wake of the Los Angeles Rams' Super Bowl LVI triumph, Aaron Donald has ensured the NFL world will have more time to marvel at his remarkable talents.

It was revealed on Monday that the Rams had restructured Donald's contract to guarantee him $95m over the next three seasons. 

No years were added to Donald's deal, but the added guaranteed money will make the seven-time All-Pro defensive tackle the highest-paid non-quarterback in NFL history.

Eye-watering money, but the Rams won't have felt the need to look even twice at a contract that arguably represents the NFL's most expensive bargain.
 

Donald's outsized impact

Simply put, no non-quarterback has done more to impact the game than Donald since he entered the league.

Drafted 13th overall in 2014, Donald has amassed 98 sacks in his pro career, the most of any player in that time, with Chandler Jones his nearest challenger on 90.

Looking at tackles for loss, none of his contemporaries come close to matching Donald's production. He has racked up 150 tackles behind the line of scrimmage since 2014, 36 more than the second-placed player on that list, Cameron Jordan.

It is a similarly absurd gap between Donald and Jordan in terms of overall quarterback pressures.

Donald has racked up an astonishing 735 pressures since entering the NFL. Jordan (544) is the only other defender even above 500.

The title of most disruptive defender in the league is one Donald has monopolised, and he has done so despite the substantial energy opposing offenses have put into slowing him down.
 

Dominating double teams

Last season, no pass rusher was the subject of more double teams than Donald, who earned the attention of two pass protectors 182 times. 

Next on the list was DeForest Buckner (164) and the margin would likely have been greater if not for Donald's versatility, which allowed him to play 11 per cent of his snaps on the edge where double teams are less prevalent. Buckner played only 3.21 per cent of his snaps on the edge.

Despite the rate at which he was doubled, Donald still recorded a stunt-adjusted pass rush win rate of 63.83 per cent. Only one other pass rusher with at least 100 one on one pass-rush snaps, Myles Garrett (53.56), posted a win rate above 50 per cent.

Doubled 95 times as a run defender, no player (min. 100 one on one run defense snaps) had a better double-team adjusted run disruption rate than Donald's 58.29 per cent. Lowering the threshold to 50 one on ones, Donald was still fourth in 2021.

The numbers don't always tell the entire story, but in Donald's unique case they are enough to encapsulate his value. He is a true unicorn who can impact the game at any point regardless of situation.

"It's not great news; it's phenomenal, outstanding, any nice adjective that you can place around it," Rams head coach Sean McVay told SiriusXM of Donald's restructure.

"It's a big deal, and he's earned it. And he truly is one of one, in my opinion. This means so much to me, to our organisation."

And Donald saved his best for the moments that meant most to the Rams last season.
 

Shining on the brightest stage

From the Wild Card Round rout of the Arizona Cardinals through to the nerve-jangling win over the San Francisco 49ers in the NFC Championship Game and the Super Bowl defeat of the Cincinnati Bengals, there was a clear theme that defined the Rams' surge to the Lombardi Trophy, one of their defensive front overwhelming opponents to tilt matters in Los Angeles' favour.

It was Donald who unsurprisingly led the charge, ably supported by Von Miller, whom the Rams will face when they raise their Super Bowl banner against the Buffalo Bills in Week 1 of the 2022 season, and Leonard Floyd.

Donald ended the postseason with 29 pressures while Miller recorded 27 and Floyd 22.

The depth of pass-rushing talent at the Rams' disposal prevented Niners quarterback Jimmy Garoppolo and Bengals star signal-caller Joe Burrow from knocking off the Rams in contests that went down to the wire.

It was fitting that the final say went to Donald, who ended the Bengals' hopes of sending the Super Bowl to overtime with a game-tying field goal by knifing past left guard Quinton Spain with his devastating hand speed and using his flexibility to flatten his angle to Burrow, flinging him to the turf as the quarterback's hurried desperation fourth-down heave fell incomplete.

A jubilant Donald pointed to his ring finger in celebration. He now has that Super Bowl ring secured, along with a contract that properly reflects his importance to the reigning champions.

Donald isn't the straw that stirs the drink for the Rams, he is the chief ingredient in a cocktail of premium talent that has propelled the Rams to the NFL mountain top.

Sure, the trade for Matthew Stafford provided the critical final seasoning for Los Angeles, but the mix doesn't work without Donald's ability to blow up the best-laid plans of their opponents.

Those foes had hoped talk of Donald's retirement would remove the headache of game-planning to try to stop him.

However, the Rams have put such hopes to bed and made sure offensive coordinators across the league will have sleepless nights for a few more years when preparing to face an all-time great who will continue to provide value for money for Los Angeles even at his new exorbitant price tag. 

Dustin Johnson has resigned from the PGA Tour in order to play in the Saudi-backed LIV Golf Invitational Series.

The two-time major winner is one of the biggest names to sign up for the new league, and his loss represents a significant blow to the PGA Tour, of which he had been a member since 2007.

Johnson's decision to turn his back on the PGA Tour means he will be unable to complete in the Ryder Cup.

"It's too early to speak on what the consequences will be, but as of right now, I resigned my membership from PGA Tour, I'm going to play here for now, that's the plan," he told reporters.

"But what the consequence are going to be, I obviously can't comment on how the Tour is going to handle it.

"The majors, again I can't answer for the majors, but hopefully they'll allow us to play. Obviously I'm exempt for the majors, so I plan on playing there unless I hear otherwise."

Adding on the Ryder Cup, he said: "The Ryder Cup is unbelievable and has meant a lot to me, but ultimately I decided this was best for me and my family.

"All things are subject to change, and hopefully at some point it will change and I will get a chance to do that again."

"One of one" Aaron Donald has earned his record-breaking contract with the Los Angeles Rams, says coach Sean McVay.

A restructuring of Donald's deal in LA will see him guaranteed $95million over the next three years, making him the highest-paid non-quarterback in NFL history.

However, for the defending Super Bowl champion Rams, it is a price worth paying.

Donald is a three-time Defensive Player of the Year and played a vital role in the Super Bowl LVI win over the Cincinnati Bengals last year.

Given the uncertainty that followed that victory, with Donald hinting at a possible retirement, McVay is simply delighted to be getting his best defender back.

"It's not great news; it's phenomenal, outstanding, any nice adjective that you can place around it," McVay told SiriusXM.

"It's a big deal, and he's earned it. And he truly is one of one, in my opinion.

"This means so much to me, to our organisation.

"I think the respect that he's garnered around this league from guys that have done it at such a high level, what he's accomplished through his eight years is unparalleled.

"And so [we] wanted to be able to find a solution to get him taken care of and have him continue to lead the way for our team, for our defense.

"We had a feeling it was trending in the right direction when he was at our wedding on Saturday night. A lot of good things have happened the last couple days for me."

As well as earning an unprecedented salary, Donald now has the freedom to retire in 2024 without any financial consequences.

First, though, the 31-year-old is "locked back in to go get us another ring", as he said in a video released by the team.

And that pursuit would be aided by the Rams also bringing back Odell Beckham – another attendee at the McVays' wedding, even if Sean claimed he "crashed" the event.

"He was a baller," McVay said of a receiver who signed for the Rams last November but was out of contract after tearing his ACL against the Bengals.

"We want to try to be able to get him back. I would love to work with him every single day."

The Boston Bruins have taken the "extremely difficult decision" to fire coach Bruce Cassidy despite reaching the playoffs in each of his six seasons.

Cassidy was appointed as coach in February 2017 – initially on an interim basis – having served as assistant since the start of the 2016-17 season. He had previously led the AHL Providence Bruins.

The Bruins made the former Washington Capitals coach their permanent hire in April of that year, and Boston made the playoffs.

The team had been missing from the postseason in the previous two seasons but would go on to be regulars with Cassidy behind the bench.

He took the Bruins all the way to Game 7 of the Stanley Cup Finals in 2019, only to lose to the St. Louis Blues.

Despite the Bruins continuing to make the playoffs, that was as close as Cassidy would come to adding a seventh championship, this year losing in the first round to the Carolina Hurricanes.

Cassidy leaves Boston having overseen 399 regular season games, the fifth-most in team history. With a record of 245-108-46, he is tied third for most Bruins wins.

General manager Don Sweeney explained his dismissal, saying in a statement: "Today I informed Bruce Cassidy that I was making a change.

"After 14 years working with Bruce, this was an extremely difficult decision.

"I want to thank and acknowledge Bruce for all his work and success with the Bruins organisation. His record for the Bruins is impressive, and we are appreciative of Bruce both professionally and personally.

"After taking some time to fully digest everything, I felt that the direction of our team for both this season and beyond would benefit from a new voice."
