Former British number one Kyle Edmund is likely to miss several more months of the season after having surgery on his left knee.

It was performed by Dr Roland Biedert, who has operated on Roger Federer, Stan Wawrinka and Juan Martin del Potro.

Edmund's problems began in October 2018, when a scan revealed fluid behind the left knee.

The 26-year-old had reached the Australian Open semi-finals that January, and just won the European Open to climb to a career-high ranking of 14.

But despite winning a second ATP title in New York in February last year, Edmund's progress since has been consistently thwarted.

He currently stands at 69 in the world and has not played since losing in the first round of qualifying in Vienna last October.

Edmund had been resisting surgery, due to the obvious risks for a professional athlete, but the nagging pain in his knee has increased since the start of the year and prevented him from practising.

A long period of rehabilitation is now underway, and an appearance at Wimbledon seems a forlorn hope.

Harlequins climbed back into the Premiership play-off places with an eight-try demolition of Worcester.

Flanker Will Evans scored two tries either side of half-time, with winger Tyrone Green and replacement Luke Northmore also going over for Quins.

Worcester scored twice late on to earn a four-try bonus point of their own.

The tries from wing Alex Hearle and replacement prop Richard Palframan and first-half scores from hooker Niall Annett and lock Joe Batley at least gave Worcester something to show from their afternoon.

But they were well beaten and slumped to a 13th defeat of the season to stay seven points adrift at the bottom of the table.

Harlequins were fresh for the game having selected a much-changed side to the one that lost to Ulster in the Challenge Cup - a defeat which afforded them a week off.

They took advantage by returning with a rampant display to keep their bid for a semi-final firmly on course.

The pick of their tries was perhaps Evans' first, as he was sent away down the right wing and dived to the corner, touching down just before Worcester scrum-half Francois Hougaard could tackle him into touch.

Harlequins: Brown; Green, Marchant, Esterhuizen, Murley; Smith, Care; Marler, Baldwin, Louw, Symons, Lamb, Lawday, Evans, Dombrandt (capt).

Replacements: Gray, Els, Collier, Tizard, Kenningham, Landajo, Herron, Northmore.

Worcester: Shillcock; Humphreys, Lawrence, Venter, Hearle; Searle, Hougaard; Waller, Annett, Schonert , Batley, G Kitchener, Hill (capt), Kvesic, Van Velze.

Replacements: Miller, Thomas, Palframan, Bresler, Dodd, Simpson, Beck, Doel.

Premiership leaders Bristol took control after a tricky start to gain a bonus-point win at Newcastle and regain their 12-point lead at the top.

But Jake Heenan ran through, Max Malins dummied his way to score and Luke Morahan twisted in as Bristol replied.

The visitors went clear with tries from Ben Earl and Malins before Kyle Cooper's consolation score for Falcons.

Pat Lam's Bears are now unbeaten in their past eight Premiership matches, winning six in a row, while 10th-placed Newcastle are on a run of five successive defeats.

Bristol made nine changes from their European Champions Cup defeat by Bordeaux-Begles and were scrappy in the opening 20 minutes, Earl's no-look pass in his own 22 cut out by Young for a try after the hosts had Brocklebank yellow-carded for a shoulder charge into the back of Callum Sheedy.

Fly-half Sheedy was forced off after the incident but Bristol soon found their stride, Earl cutting inside, accelerating and playing a reverse pass for Heenan to score before Malins, on his first start of 2021, wrong-footed two defenders to go over.

Newcastle's Young then missed a tackle on Morahan to allow the table-toppers to hold a 19-10 half-time lead.

England back-row Earl took a lovely line on an inside angle for Bristol's fourth try and though Niyi Adeolokun was denied a score after a knock-on, Malins sprinted through for his second after a Falcons chip over the defensive line took an unfortunate bounce.

Bristol host second-placed Exeter at Ashton Gate on Friday.

Newcastle: Penny; Vuna, Wacokecoke, Lucock, Stevenson; Flood, Young; Brocklebank, McGuigan, Mulipola, Peterson, Robinson, Welch, Wilson (capt), Chick.

Replacements: Blamire, Cooper, Ah You, Fuser, Van der Walt, Schreuder, Connon, Graham.

Bristol: Malins; Morahan, O'Conor, S Piutau (co-capt), Adeolokun; Sheedy, Uren; Y Thomas, Capon, Afoa, Joyce, Vui, Harding, Earl, Heenan (co-capt).

Replacements: Kloska, Woolmore, Lahiff, Holmes, D Thomas, Kessell, Lloyd, Leiua.

Auto racing at the Bloomsburg Fair, the largest fair in Pennsylvania, dates back to the roaring ’20s. Many notable drivers, especially those who raced midgets, have competed there, including household names such as Mario Andretti.

Racing at the fair came to an end when a car landed on a vendor’s stand in the mid-’80s. No one was injured, but the fair’s board of directors decided racing was too much of a liability to continue. Some of the ARDC midget drivers who competed there also felt that half-mile tracks like the one at the fairgrounds generated too much speed for a midget.

Hometown hero John Heydenreich, a four-time winner of races at the Bloomsburg Fair track, won the last race on its half-mile cinder oval in 1987. That event was promoted by another hometown hero and driver, Randy Mausteller.

A new era will dawn this spring, however, as a new three-eighths-mile dirt oval known as Bloomsburg Fairgrounds Raceway will open at the fairgrounds on May 29 with a USAC Eastern sprints and ARDC midgets doubleheader. It will be the first race at the track in 34 years. Heydenreich plans to compete there this year in selected events and he and many other drivers and fans are more than a little excited about racing returning to Bloomsburg.

There are eight events on the track’s schedule. Brian Wawroski, a member of the fair’s board of directors, said the intention is to run 12-15 special events each.

The promoter will be five-time National Sprint Car Hall of Fame Promoter of the Year Steve O’Neal, who is taking on these special events in addition to his work at Port Royal Speedway.

“Port Royal and Bloomsburg want to work together,” Wawroski said. “We’re not wanting to compete with Port Royal, and by having Steve on board as the promoter, he won’t allow that to happen. We’re doing special events only, too. We don’t want to make it a weekly event.”

The new clay track is being built inside the old half-mile cinder track, which will still be used for horse racing during the fair. There will be about 10 percent banking in the turns and slight banking on the straightaways of the new track.

The existing grandstand that seats 5,500 will be kept. All of those seats have backs. The red seats, which account for about a third of the seating, are individual seats and the remainder are bleacher seats. Additional bleachers will be brought in and a dirt viewing mound for the pit area is also being contemplated. Musco lighting is being installed.

Construction cost is an estimated $1 million, which is being undertaken by the fair and its sponsors.

The revitalization of racing at the fair was spurred on by discussions last summer.

“The Armory Group and USAC were in town for our Monster Truck Jamboree last July,” Wawroski explained. “The Armory Group builds an infield track at the fair for the jamboree. We were all talking about how nice it would be to have racing again at the fair and we all agreed we wanted it to be top-notch. So we started talking about it seriously, and things progressed.”

The Armory Group is doing the construction and USAC’s Levi Jones is a consultant on the project.

“He helped design the track and sent us in the right direction,” Wawroski said. “We added banking to turns three and four, and when that’s done, he’ll come in and test it. He has in mind a track that will be able to host several different divisions of racing, such as late models and modifieds, and not just midgets and sprint cars. Our first race will be a USAC event. Having USAC come in is a huge thing for the Bloomsburg Fair Raceway and for the community.”

The USAC AMSOIL National Sprint Car Series will visit the track June 20 and the USAC midgets have an Aug. 6 event there.

The URC sprints have two dates, as does the ULMS late model series. The Short Track Super Series modifieds visit July 14 and the Pa. Sprint Series 305 sprints share the card with them on July 25. Details have yet to be announced for the card on Oct. 2, which will be a highlight of the 166th annual fair that runs Sept. 24 through Oct. 2.

Buffalo Sabres forward Kyle Okposo will miss the rest of the season after undergoing surgery to repair a broken bone in his cheek, the team announced Saturday.

Okposo was injured when he was hit in the face by a puck during Thursday's win over the Washington Capitals.

The 32-year-old finishes the season with two goals and 11 assists in 35 games.

The Sabres have been struck by a rash of injuries lately, including goaltender Linus Ullmark being week-to-week with a lower-body injury and captain Jack Eichel being ruled out for the season with a herniated disk.

Glamorgan 285 and 258 for 5 (Carlson 129*, Robinson 4-59) lead Sussex 481 (van Zyl 113, Garton 97, Haines 87, Robinson 67*, Thomason 67) by 62 runs

Kiran Carlson scored his second hundred of the match as Glamorgan brought themselves back into the contest against Sussex in the LV=Insurance County Championship.

Sussex finished their first innings on 481 all out, 196 runs ahead of Glamorgan. As in the first innings of this match, Glamorgan's top order struggled but Carlson came to the rescue once again.

Ollie Robinson was a class apart, claiming 4 for 59, but the other Sussex bowlers struggled to match his penetration.

Carlson's 129 means that Glamorgan go into the last day leading by 62 runs with five second-innings wickets in hand.

It took just three balls to wrap up the Sussex first innings with Robinson dismissed for 67 and no runs added to the overnight score.

With Glamorgan having a large hill to climb to bring themselves back into this match they wanted a strong start from their top order. Robinson prevented that from happening, claiming three lbw dismissals before lunch. With Henry Crocombe chipping in with an lbw of his own Glamorgan found themselves four wickets down for 95, still 101 behind.

It was then that Carlson stepped up. He had finished undefeated on 127 in the first innings, and he cruised to another century, this one coming from just 115 balls. While Carlson was finding things easy the same could not be said for the rest of the Glamorgan top order with Chris Cooke lucky to survive when he was dropped on three off the bowling of Jack Carson.

Cooke departed for 12 when he feathered an edge to Ben Brown off the impressive Robinson to leave Glamorgan 150 for 5. It was then that Carlson found some support from Calum Taylor as they took Glamorgan into the lead.

With Carlson and Taylor looking untroubled by seam Sussex turned to the spin of Carson and Delray Rawlins to see them to the new ball and they were creating chances. Carson was unlucky not to claim the wicket of Taylor when another chance went down at first slip.

Robinson looked dangerous with the new ball but Carlson and Taylor stood firm, taking their partnership past the 100 mark to reach the close with Glamorgan on 258 for 5 heading into the final day.

While the top-order trio of Babar Azam, Mohammad Rizwan and Fakhar Zaman shone brightly during Pakistan's 3-1 T20I series win in South Africa, the performances of the middle and lower order weren't quite as convincing. The final match of the tour was a case in point: Pakistan slipped from 92 for 1 to 129 for 7 before Mohammad Nawaz steered them home in a chase of 145.

One middle-order batter who came under the spotlight in particular was Haider Ali, who made scores of 14, 12 and 3 in his three visits to the crease during the T20Is. Pakistan's batting coach Younis Khan has termed the 20-year-old Haider a "future star", and has backed him to succeed, given enough chances to settle into his role in the side.

"Haider is a future star and very much capable," Younis said in a virtual conference. "His natural game is attacking, and I still remember he smacked a six off his very second ball on debut. I understand he has played a lot of games since then, and missed a few opportunities to grow, but we have to give him time [to grow into his role]. He was opening in the previous series, and then, when he was playing in the PSL for his franchise, he put up some amazing performances lower down the order. Here too we tried to use him in that [middle-order] role.

"I struggled for four years when I came into international cricket. I was lucky that my performances didn't get highlighted. But at the same time when you come into international cricket there is a big responsibility on the player himself. You represent a 220 million population and it's up to you in the end, regardless of anything. You have to prepare yourself for this big opportunity and you have to give everything to make it count. We have a responsibility as a coach but the players are growing into their roles, and they will make mistakes, otherwise you can't learn."

Haider made his T20I debut during the tour of England last year, scoring a half-century on debut batting at No. 3. After batting in that position in his first five T20Is, he has moved up and down the order, opening on three occasions and batting at No. 5 during the tour of South Africa.

All that shuffling has coincided with a lean patch. After starting his career with two fifties in his first three innings, he's only crossed 20 once in his last nine innings, causing his overall average to drop to 20.91. Asif, meanwhile, has struggled to replicate the hitting ability he's shown in domestic T20s in international cricket. While he averages 25.06 and boasts a strike rate of 146.98 in all T20 games, his corresponding T20I numbers are a modest 17.14 and 124.72 respectively.

Reflecting on the overall performance of the middle order, Younis said the batters are still learning their roles, and will learn from their mistakes in time.

"It's a young team, players are settling, and they aren't clear about their [batting positions] yet, but they will be going forward," Younis said. "We have the Zimbabwe series now, and it's a good chance for the youngsters to go out and play the role that is being worked out for them, and in which we want to see them grow, because we have some very tough cricket coming up, with the T20 World Cup in India. The top order is vital, but the lower order is equally important, which is where we are lagging behind, and we have to address this to get to the top."

At the same time, Younis urged the batters to take ownership of their own performances in order to raise their game.

"We are playing constant cricket day and night and we can't really push players all the time. They should themselves understand. There is not much time to do technique work, [we focus] mainly on the tactical aspect. I speak with players and always tell them not to come back without finishing their job, but then in the last T20 for example we saw Fakhar and Babar left it unfinished and suddenly the situation turned out that we couldn't even score a run a ball.

"Players need to understand their game and take ownership of their performance. It's not club-level cricket where us coaches can discipline a player using a stick. We do have a role but the players need to themselves realise how they can bring success to their game."

Younis joined the Pakistan set-up in England last year and has taken on the role full-time since the 2020-21 tour of New Zealand. Over the last one year, Pakistan have picked a number of players without too much experience in domestic cricket, often turning to youngsters who have shown flashes of brilliance in the T20 format, particularly in the PSL.

Younis believes a player must have a certain amount of experience in domestic cricket before being picked for Pakistan, in order to be ready for all the situations that international cricket may throw their way.

"If you are picking anyone for Test cricket then he should have sufficient first-class experience behind him," Younis said. "If it's for T20 or one day he should have played adequate List A games. But then these days, whether it's the media, or the commentators, or YouTube channels, they build pressure on teams, coaches, and selectors to pick certain players. They say, 'pick this player,' because they think he is ready, but then he has played only two T20 matches. So this pressure is created by the media prompting selectors to pick players.

"We speak about young blood a lot, and yes, T20 and one-day cricket are about young blood. But it's also important to pick players who are mature, who have the fitness and the commitment, and who have enough cricket under their belt. It's important to pick the best players who have the experience, and who won't score five runs an over when you need 10 an over, and won't aim for 15 runs an over when you need five an over."

When asked how much time a player should be given before the selectors make a final decision, he said: "I am a batting coach and very much part of the support staff, but the final decision about the selection of any player isn't mine. It's not my decision on how many opportunities a player should be given - for all this, we have chief selectors, head coach and captain, and it's their prerogative. But in my personal opinion if any player plays two to three series, he will perform if he has the caliber. So I can only give my recommendation but the final decision lies with the captain and head coach. We are trying to figure out a right combination with players who are suitable for different situations and who can perform."

Presumptive No. 1 overall pick Trevor Lawrence said in a series of tweets Saturday that quotes made by him that have led some to question his motivation are being "misread."

"I am internally motivated - I love football as much or more than anyone. It is a HUGE priority in my life, obviously. I am driven to be the best I can be, and to maximize my potential. And to WIN," Lawrence explained in the first of three tweets.

He added as part of a second tweet, "I don't need football to make me feel worthy as a person," but that he truly loves everything that comes with the game.

The sentiment that football is not everything to Lawrence echoes comments he made in a Sports Illustrated article published earlier this week. In that piece, the Clemson quarterback said, "It's not like I need [football] for my life to be O.K. I want to do it because I want to be the best I can be. I want to maximize my potential. Who wouldn't want to? You kind of waste it if you don't."

"It's hard to explain that because I want people to know that I'm passionate about what I do and it's really important to me, but ... I don't have this huge chip on my shoulder, that everyone's out to get me and I'm trying to prove everybody wrong," he told Sports Illustrated. "I just don't have that. I can't manufacture that. I don't want to."

Those comments led some to criticize the man most expect to be the Jacksonville Jaguars' franchise quarterback.

Lawrence seemed to answer those detractors.

"I have a lot of confidence in my work ethic, I love to grind and to chase my goals. You can ask anyone who has been in my life," Lawrence tweeted. "That being said, I am secure in who I am, and what I believe."

The quarterback closed out his rebuttal by disclosing his outlook on life and also with a joke.

"I am a firm believer in the fact that there is a plan for my life and I'm called to be the best I can be at whatever I am doing," he tweeted. "Thanks for coming to my TedTalk lol."

KANSAS CITY, Mo. -- The Kansas City Royals traded outfielder Nick Heath, who had been designated for assignment earlier in the week, to the Arizona Diamondbacks for minor league pitcher Eduardo Herrera on Saturday.

The 27-year-old Heath, a speedster with a spotty bat, has been on the fringe of making the Royals' major league club the past several years. He finally made his debut last year, appearing in 15 games in the shortened season for Kansas City.

With a glut of outfielders, though, the Royals decided to trade Heath for some additional bullpen depth.

The 21-year-old Herrera signed with Arizona as an international free agent in 2016. He began his career as a catcher and infielder but converted to pitching two years ago with promising results. He has yet to move beyond Class A.
