Andy Murray had to hold back the emotion as he celebrated a winning return to the ATP Tour at Queen's.

Murray had hip surgery in 2019 and had not won a grass-court game since 2018, with last year's season having been cancelled due to the coronavirus pandemic.

Having struggled with a groin injury, the 34-year-old Scot last played in March, yet showed flashes of his old self in his 6-3 6-2 victory over Benoit Paire, having taking up a wildcard into the pre-Wimbledon tournament.

It was an emotional moment for Murray, who said: "Look, I love playing tennis."

The five-time champion was fighting back the tears as he continued: "Obviously, competing is why you put in all the hard work.

"The last few years, I've not got to do that as much as I would have liked so, yeah it's just great that I'm out here and able to compete again.

"The body is old, but I did quite well today in terms of my movement.

"It's my first match on grass in three years and I've only played three or four practice sets in the build-up to this, so I didn't know exactly how I was going to play or feel – but I think for a first match it was good."

Murray will face top seed and world number nine Matteo Berrettini, who defeated Stefano Travaglia 7-6 (7-5) 7-6 (7-4).

British number one Dan Evans beat Alexei Popyrin, while fourth seed Alex de Minaur also progressed to round two, having come from behind against Laslo Djere. Second seed Denis Shapovalov overcame Aleksandar Vukic.

Tuesday's results mean, for the first time since 2005, four British players have won at Queen's, with Cameron Norrie and Jack Draper having gone through on Monday.

Meanwhile, after losing to Stefanos Tsitsipas in the French Open quarter-finals, world number two Daniil Medvedev crashed out of the Halle Open in the first round.

Jan-Lennard Struff was his conqueror, claiming a 7-6 (8-6) 6-3 triumph, which the German labelled as "the biggest win of my career."

There was better luck for third seed Alexander Zverev, though he did need three sets to see off Dominik Koepfer 6-4 3-6 6-3, just four days after facing Tsitsipas in the Roland Garros semi-finals.

Ugo Humbert awaits Zverev, while Felix Auger-Aliassime beat Hubert Hurkacz to tee up a tie with Roger Federer. World number seven Andrey Rublev got the better of Karen Khachanov.

The Philadelphia 76ers and the Atlanta Hawks are locked together at 2-2 in the NBA playoffs as their battle to reach the Eastern Conference Finals continues on Wednesday.

After losing the opener at home, the 76ers appeared to assume control by taking the next two games to forge ahead.

However, with Joel Embiid enduring a second half to forget, the Hawks hit back on Monday, a 103-100 triumph leaving the situation delicately poised as the series switches back to Philadelphia for Game 5.

For a franchise linked with the catchphrase "trust the process", the key for the 76ers – who are the top seeds in the East – is believing in each other, according to head coach Doc Rivers.

Asked for the reason behind his team's loss in Atlanta, he said: "We stopped passing. I thought we started the game that way, then got back into ball movement, then went to hero basketball.

"Basically, everybody wanted to be the hero, rather than trusting the team and trusting each other.

"If you do that, you usually lose, especially when the other team outworks you the whole game, and that's what they did."

Embiid – a player who arrived via the draft amid a patient rebuild that prioritised long-term planning over immediate results – endured a difficult outing in Atalanta, going 4-for-20 as he missed all 12 of his shots in the second half. That run included an unsuccessful lay-up in the closing seconds that would have put his team ahead.

Bothered by a knee injury suffered in the opening round against the Washington Wizards, Embiid saw his offensive production drop dramatically.

A temporary blip or a greater cause for concern? Only time will tell, but the 76ers will not want to fall behind knowing they have to travel to Atlanta for Game 6.

PIVOTAL PERFORMERS

Tobias Harris – Philadelphia 76ers

Harris is averaging 23.2 points per game in the playoffs, easily a career high. He is shooting at 40 per cent from deep too, becoming a consistent contributor for his team on offense. However, with Embiid not at full power, the 28-year-old may have to ease the strain on his ailing team-mate by taking on an even greater workload.

Trae Young – Atlanta Hawks

Young created NBA history in Game 4, becoming the youngest player to have 18 or more assists in a postseason game. He also scored 25 points, with his fifth double-double of the playoffs demonstrating his importance to this Hawks outfit. No individual had managed both 25 points and 18 assists in a playoff outing since Tim Hardaway back in May 1991.

KEY BATTLE – Embiid against his ailing knee

"I'm just trying to do the best I can," Embiid said when talking to the media after Game 4. The center – runner-up to fellow big Nikola Jokic in the MVP race – is having to deal with a partially torn meniscus at just the wrong time in the season.

He sat out Game 5 against the Wizards as the 76ers sealed a semi-final spot, but with this series so delicately balanced there is little time to take a break.

The Hawks, who have won only three of 24 best-of-seven series in which they found themselves 2-1 down – will sense the chance to strike on the road as they aim to reach the Conference Finals for the first time since 2015.

HEAD TO HEAD

This is the third playoff series between the teams, with the 76ers progressing in both 1980 and 1982. They also won two of the three meeting in the regular season, though the Hawks have already prevailed once in this series in Philadelphia.

T.J. Watt refused to discuss the subject of his contract negotiations with the Pittsburgh Steelers on Tuesday as he enters the final year of his rookie deal.

The star edge rusher is set to be a free agent in 2022 and, regardless of whether he remains in Pittsburgh beyond 2021, is primed to receive a lucrative contract following a stellar start to his career.

A first-round pick in 2017, Watt has 49.5 sacks to his name since entering the league, with that tally third behind three-time Defensive Player of the Year Aaron Donald (57.5) and Chandler Jones (50).

Still only 26, Watt can likely expect a deal in the region of the five-year, $135million extension signed by Los Angeles Chargers defensive end Joey Bosa in July last year.

But, as the Steelers continued their preparations for the 2021 campaign with their mandatory minicamp, Watt decided against discussing his talks with Pittsburgh.

"With respect to the process, I'm not going to be talking about any contract stuff today, " Watt told reporters.

Watt missed out on the Defensive Player of the Year award despite a 2020 season that saw him lead the league in sacks with 15. Donald was second with 13.5, though his pressure rate (28.2%) was superior to that of Watt (25.8).

However, Watt is not thinking about being snubbed for that prize.

"I don't think it's driving me. [The] big thing for me is realizing all the plays I didn't make last year," he added. 

"Yeah, there's a lot of good from last year, but there's still a lot to improve on."

The Brooklyn Nets could yet be boosted by the return of James Harden on Tuesday after he was upgraded to doubtful.

Harden had initially been ruled out of Game 5 against the Milwaukee Bucks in the Eastern Conference semifinals.

The former Houston Rockets star has been managing a hamstring injury since the start of April.

Harden, who had been making an MVP run prior to the initial setback, returned in the closing stages of the regular season.

He then averaged 27.8 points per game in the first-round series against the Boston Celtics but bowed out 43 seconds into Game 1 at home to the Bucks.

The potential for Harden to feature in Game 5 lifts the Nets, who have also now lost Kyrie Irving to an ankle issue.

Having gone 2-0 up against Milwaukee without Harden, Brooklyn lost both games on the road to level the series.

Kevin Durant has led the team with 29.8 points per game in the series but was limited to nine-of-25 shooting in Game 4.

Only five men have achieved golfing immortality by winning each of the four majors and completing the coveted Grand Slam.

Jack Nicklaus, Tiger Woods, Ben Hogan, Gary Player and Gene Sarazen stand alone among the pantheon of greats to have topped the leaderboard at The Open, the U.S. Open, the US PGA Championship and the Masters.

Arnold Palmer, Tom Watson and Walter Hagen are among the sport's legends to have accomplished three legs of the Slam – an impressive feat in itself.

Indeed, three active players are just one away and each is eyeing a different title. Rory McIlroy is missing a Masters, Jordan Spieth a PGA Championship and Phil Mickelson a U.S. Open.

For Mickelson, it is certainly not for want of trying – on six occasions he has finished second or tied second for a prize he so greatly craves.

It appeared as though his chances were waning as Father Time had seemingly caught up with a true great. But then, Mickelson upset all the odds to win a sixth career major and second PGA Championship at Kiawah Island last month at the age of 50, making him the oldest player to win a major tournament.

With renewed hope at finally claiming the missing piece of the puzzle, we assess the chances of Mickelson, Spieth and McIlroy in the race to complete the Grand Slam.

PHIL MICKELSON

In terms of a straight race, you could argue that 'Lefty' is in pole position merely because his opportunity is next up.

Moreover, Mickelson has history at Torrey Pines – hosting the U.S. Open for the second time having last done so in 2008 – a venue where he is a three-time winner, albeit the last of those was in 2001.

But that in itself is testament to Mickelson's astonishing longevity, and he made a mockery of suggestions his major-contending days were over at Kiawah Island.

Still, to mix it at that sort of level in the 50s (Mickelson turns 51 on Wednesday) on a regular basis is tough. Indeed, the unexpected triumph was his only top-10 finish on the PGA Tour this season, while he ranks down at 167th for scoring average.

While he does impressively still average over 300 yards off the tee (302.8), in terms of fairway accuracy Mickelson is down at 199th (51.16 per cent), and a putting average of 1.791 would need to be improved to contend.

All in all, you would be a fool to say Mickelson cannot complete the Slam but, speaking pragmatically, even accounting for his PGA Championship heroics, it will take a monumental effort to go back-to-back in the majors this weekend.

RORY MCILROY

A player of outrageous talent whose career in terms of majors has perhaps not quite hit the heights many tipped him to reach.

McIlroy has four to his name thus far, the last of which arrived at the 2014 US PGA Championship. At that stage, it appeared a question of how many he would win. 

It has been a decidedly mixed bag since at the majors, and there is no doubt winning a green jacket is a prize McIlroy would crave above all others in his career.

There have been plenty of close calls at Augusta, where he has six top-10 finishes, and that does not include the 2011 tournament where McIlroy led heading into the final round before enduring an excruciating Sunday that saw him finish way down in 15th.

Once upon a time it would have sounded unthinkable McIlroy would never win a Masters. It's not as clear cut now perhaps, but there are many opportunities left for a player still only 32 years of age.

McIlroy has endured inconsistent form this season, but was a recent winner at the Wells Fargo in a sign that things are slowly starting to click back into place.

His scoring average of 70.363 is the 31st best on the PGA Tour this season, while he ranks tied 14th for top-10 finishes (five).

Only Bryson DeChambeau averages longer off the tee than McIlroy's 318.6 yards but he is way down in 173rd for driving accuracy, while a putting average of 1.740 is something he will be keen to improve.

JORDAN SPIETH

One of the most pleasing aspects of recent months has been the resurgence of Spieth, who had slipped as low as 92nd in the world rankings having missed the cut at the Farmers Insurance Open earlier this year.

But eight top-10 finishes – including a win at the Valero Texas Open – has catapulted him back up to 23rd and many fancied him to complete the Slam at the PGA Championship.

Despite fleeting flashes of promise, Spieth could only finish down in 30th but crucially – much like McIlroy – time is on his side. Indeed, due to the early career success that has seen him become a three-time major victor, it is easy to forget he is only 27.

Prior to Mickelson's triumph last month, the smart money would have been on either McIlroy and Spieth to do the Slam first and perhaps it still is.

Indeed, Spieth probably remains a solid bet to deny Mickelson's own hopes this weekend. He is 21st for scoring average (70.178) and second only to Jon Rahm (10) for top-10 finishes with eight.

Not known as a particularly big hitter off the tee, Spieth is down at tied 83rd for driving distance (298.0) and 184th for driving accuracy but only nine players have a lower putting average than his 1.716.

VERDICT:

In terms of immediate chances then, yes, of course Mickelson has the edge. But logic suggests that it will need a monumental effort for him to repeat what he did at Kiawah Island at Torrey Pines. McIlroy and Spieth can, theoretically at least, continue to compete at the top for the best part of the next two decades. If they do, both have ample opportunity to secure the Grand Slam. As for who does it first…well given the Masters is closer than the PGA then let's go with McIlroy. Check again next April!

Kawhi Leonard's huge dunk in the Los Angeles Clippers' series-levelling win over the Utah Jazz sent ripples through the NBA, stopping Joel Embiid in his tracks.

Embiid was undertaking post-game media duties after the Philadelphia 76ers were beaten by the Atlanta Hawks, when his attention was diverted by seeing Leonard in full flow.

"Oh my god. See that dunk, see that Kawhi dunk?" said Embiid.

Unlike Embiid, Leonard finished on the winning side in Monday’s playoff games, his 31 points helping the Clippers post a 118-104 victory over the Utah Jazz in Game 4 of their Western Conference semi-final.

Leonard's masterpiece came near the end of the second quarter.

"I don't get to see the reaction of what's on the web or social media or whatever, but Zu [Ivica Zubac] showed me a clip of Embiid talking, and yeah that's the only thing I got from it. During the game in the heat of the moment I know it's a big play, but you've got to have the next-play mentality because right after I think Joe Ingles came down and hit a three pretty wide open in that corner, so we've still got room for improvement," Leonard said.

Leonard sat out the closing minutes after appearing to hurt his knee, but when asked about the blow after the game he said the knee was "good", eager to move on to the next question.

When asked about the team's prospects of reaching the Western Conference Finals for the first time, Leonard almost scoffed at that being his ambition.

He said: "I don't care about the Western Conference Finals. I'm trying to win a championship.

"Obviously that's the next step but I'm not even looking at that."

Paul George also scored 31 points as the Clippers edged out the Jazz at Staples Center, teeing up Game 5 in Utah on Wednesday.

Having been 2-0 down in this series, the Clippers have set aside criticism of their slow start to look sharp again.

Leonard indicated he was impervious to external discussion surrounding the team's performance.

"I don't even know we took criticism," he said. "I don't know what's going on in the outside world."

Donovan Mitchell said Kawhi Leonard "destroyed" the Utah Jazz in Game 4's 118-104 defeat to the Los Angeles Clippers, but he is bullish the top seeds can get back to winning ways.

Leonard scored 31 points with seven rebounds and three assists for the Clippers, well supported by Paul George with 31 points and nine rebounds as they levelled up the series at 2-2.

Mitchell put up 37 points for the Jazz but it was not enough, after his side trailed by 24 points at half-time following the Clippers' first-half blitz.

"He destroyed us, he had a hell of a game," Mitchell said about Leonard, who finished the game on the bench after a knock to his knee from a collision with Joe Ingles.

Leonard refused to be drawn on the potential injury, declining to address it in-depth in his post-game video conference and saying on court: "Nah, I'll be good."

Mitchell said that the Clippers were on a "different level" but was buoyed by his side's second-half display.

"They had three guys with 20 points or more, they got going," Mitchell said. "We can't let a team like that get going because they're lethal."

He added: "They just were at a different level. We couldn’t buy a bucket.

"Sometimes that's the case but we've got to continue to guard. I think we found a few things that will give us an advantage. We started being aggressive and that's how we cut it to 10-12.

"If we can continue to play like we did in the second half… come out in Game 5 and be ready, I think we'll be in good shape but we've also got to guard too."

On Wednesday the series returns to Salt Lake City where the Jazz won the opening two games, before the Clippers won the next two in Los Angeles.

"We've got to take care of home court," Mitchell said. "They came out and punched us in the face two times. We've got to be ready for it."

The Boston Red Sox reversed their form against the free-scoring Toronto Blue Jays with a walk-off win as Rafael Devers drove in Alex Verdugo in the ninth inning on Monday.

The Blue Jays had already piled on 14 home runs in the three games of the series against the Red Sox before Monday's meeting but the Red Sox bucked that trend with Nathan Eovaldi on the hill.

Eovaldi kept big-hitting sluggers Vladimir Guerrero Jr and Marcus Semien quiet early on, with Enrique Hernandez scoring for the Red Sox in the third inning.

Boston held that lead until the top of the ninth inning, when Guerrero unleashed a 451-feet home run, his 22nd of the season. It was the first time in 22-year-old Guerrero's career he has scored home runs in four consecutive games.

At the bottom of the ninth inning, Devers stepped up and hit a long ball off the wall, allowing Verdugo to score for the walk-off win. It was Devers' third career walk-off hit.

The result lifts the Blue Jays to 33-31 behind the Red Sox on 40-27 in the American League East.

Meadows and Randy lift Rays

The Tampa Bay Rays, first in the American League East, won 5-2 over the Chicago White Sox, leaders in the American League Central.

Austin Meadows continued his excellent 2021 slugging form with his 15th home run of the season.

The early double was the first runs allowed in the first innings this season by White Sox pitcher Lance Lynn, who had the second-best majors ERA this season coming in, at 1.23.

Rays pitcher Tyler Glasnow tossed down 53 pitches with four strikeouts before exiting early with elbow inflammation troubling him.

But the Rays got the job done without him, as the resurgent Randy Arozarena homered in the eighth inning, for his ninth of the season.

The San Francisco Giants made it six consecutive wins over the Arizona Diamondbacks with a 5-2 win.

Brandon Crawford hit a two-run shot at the bottom of the fifth inning to open up a 3-1 lead, his 15th home run of the season.

Will Smith and Chris Taylor hit home runs as reigning World Series champions, the Los Angeles Dodgers, won 3-1 over the Philadelphia Phillies.

Travel woes for the Padres

The San Diego Padres were one of the teams to watch earlier this season but they have been having some scoring issues on the road. Star man Fernando Tatis Jr represented that, going 0/4 including two strikeouts in their 3-2 loss to the Colorado Rockies. San Diego have lost seven of their past eight road games.

Red hot Schwarber

Washington Nationals left-hander Kyle Schwarber is in hot form and he continued that run with his fourth home run in three days as the Nats won 3-2 over the Pittsburgh Pirates. The 28-year-old now has 13 home runs for the seaosn.

Monday's results

Washington Nationals 3-2 Pittsburgh Pirates
New York Mets 5-2 Chicago Cubs
Boston Red Sox 2-1 Toronto Blue Jays
Cleveland Indians 4-3 Baltimore Orioles
Tampa Bay Rays 5-2 Chicago White Sox
Cincinnati Reds 10-2 Milwaukee Brewers
Detroit Tigers 10-3 Kansas City Royals
St Louis Cardinals 4-2 Miami Marlins
Colorado Rockies 3-2 San Diego Padres
Oakland Athletics 8-5 Los Angeles Angels
San Francisco Giants 5-2 Arizona Diamondbacks
Los Angeles Dodgers 3-1 Philadelphia Phillies
Seattle Mariners 4-3 Minnesota Twins

Cubs at Mets

The National League East leaders, the New York Mets (33-25), continue their entertaining series against the National League Central leaders, the Chicago Cubs (38-28).

Joel Embiid said he was bothered by his knee problem after struggling on the floor as the Philadelphia 76ers squandered a lead in their 103-100 loss against the Atlanta Hawks.

Embiid appeared to be hampered by the meniscus strain he sustained in the Eastern Conference first-round win over the Washington Wizards, missing a close-range layup 8.8 seconds from the end with the 76ers trailing the Hawks 101-100 on Monday.

NBA MVP runner-up Embiid went 0-for-12 shooting the second half, having spent some time in the locker room, as the Hawks – overturning an 18-point lead – rallied past the top-seeded 76ers to level the Eastern Conference semi-final matchup.

Embiid, who finished with 17 points and a playoff career-high 21 rebounds, told reporters post-game: "Great look. Great look. I just didn't have the lift.

"Thought I got fouled, too. But usually I would go up, especially for a bucket like that, try to dunk it.

"Try to get fouled and get an and-one. But ... not being able to jump for obvious reasons. ... It's tough."

Philadelphia's Embiid sustained a small meniscus tear in Game 4 of the first-round series against the Wizards, returning for the semi-final opener with the fifth-seeded Hawks.

"I guess it's already known," Embiid – the first Sixers player to have 20 or more rebounds in a postseason game since Hall of Famer Dikembe Mutombo in 2001 – said. "Don't need to explain ... I'm just trying to do the best I can.

"I thought in the beginning of the game, when I went back to the locker room, I just felt like I didn't have it tonight," added Embiid, who became the eighth 76ers player ever with at least 20 career double-doubles in the playoffs.

Paul George and Kawhi Leonard led the way as the Los Angeles Clippers topped the Utah Jazz 118-104 in Game 4 to level the Western Conference semi-final series.

George and Leonard posted 31 points each to lead the fourth-seeded Clippers past the Jazz in Los Angeles on Monday.

Entering the contest, George and Leonard were the only pair of Clippers team-mates to score 30-plus points in the same playoff game more than once (Game 3 and Game 5 of the first round in 2020).

George and Leonard combined again to see off the top-ranked Jazz – a win fuelled by a 30-13 blowout in the opening quarter at Staples Center.

Marcus Morris Sr. was the only other Clippers player with double-digit points as the Phoenix Suns await the winner of this series in the Western Conference Finals.

The Jazz – who had their six-game winning streak snapped in Game 3, a run which tied the second longest in franchise history – were led by Donovan Mitchell's game-high 37 points on the road.

Game 5 of the series will be held in Utah on Wednesday, with the Jazz seeking to reclaim the lead.

Trae Young was the inspiration behind the Atlanta Hawks' series-tying 103-100 victory over the Philadelphia 76ers in the Eastern Conference.

After a cold start, Young finished with 25 points to lead the Hawks' rally as Atlanta upstaged the top-seeded 76ers in Game 4 at home.

The 76ers blew an 18-point lead and the series advantage, with the matchup now deadlock at 2-2 following Young's performance.

Young became the first player to record at least 25 points and 18 assists in a playoff game since Tim Hardaway in 1991, while the all-Star is the youngest player in NBA history to have 18-plus assists in a postseason contest – surpassing Spud Webb (1986).

He also became the first Hawks player with 15-plus points and 15-plus assists in a playoff game since Doc Rivers – now head coach of the 76ers – tallied 16 points and 18 assists in 1988.

John Collins (14 points and 12 rebounds) and Clint Capela (12 points and 13 rebounds) added double-doubles, while Bogdan Bogdanovic contributed 22 points.

Joel Embiid – who looked far from his best after going 0-for-12 shooting in the second half – missed an open lay-up in the dying stages, before Seth Curry's unsuccessful buzzer-beating three-point attempt to force overtime.

Embiid, appearing to be hampered by his ongoing meniscus issue, had a playoff career-high 21 rebounds to go with 17 points.

The series heads back to Wells Fargo Center in Philadelphia for Game 5 midweek.

Bucks at Nets

The Brooklyn Nets will be without Kyrie Irving and James Harden for Tuesday's visit of the Milwaukee Bucks in Game 5 of the Eastern Conference semi-finals, which is level at 2-2.

Philadelphia 76ers head coach Doc Rivers slammed his side for playing "hero basketball" as the Eastern Conference top seeds surrendered their lead against the Atlanta Hawks in the semi-finals.

The 76ers squandered a 13-point advantage in Atlanta, where the Hawks rallied to a 103-100 victory in Game 4 in the NBA playoffs on Monday.

Atlanta levelled the second-round matchup at 2-2 after 76ers All-Star and MVP finalist Joel Embiid missed an open lay-up in the dying stages, before Seth Curry's unsuccessful buzzer-beating three-point attempt to force overtime.

The 76ers saw their lead whittled away as the Hawks overpowered the visitors, irritating Rivers post-game.

"We stopped passing. I thought we started the game off that way," Rivers told reporters. "Then we got back into the ball movement and went back to hero basketball. Basically everybody wanted to be the hero instead of trusting the team, trusting each other.

"When you do that you usually lose especially when the other team outworks you the whole f****** game and that's what they did today."

Embiid, who has been battling knee issues during the playoffs, finished with 17 points and a playoff career-high 21 rebounds, yet appeared hampered.

Philadelphia's Embiid sustained a small meniscus tear in Game 4 of the first-round series against the Washington Wizards, returning for the semi-final opener with the fifth-seeded Hawks.

Rivers was unable to provide an update on Embiid's injury status.

"I don't know. He went in the back [to the locker room]," Rivers said. "I know something was bothering him but I'm not sure what it was."

Rivers refused to criticise Embiid for his late miss at 101-100, nor his side's final play for Curry's tough shot on the buzzer.

"To me the game should never have come to that point," Rivers said. "We missed so many opportunities. My eyes told me we blew a golden opportunity tonight."

On the final play, Rivers added: "It's seven seconds, you've got to go the length of the floor.

"That's what we drew up but anybody could have been open. We got a decent shot, Seth had a decent look, thought he'd made it."

Rivers felt the Hawks were the "more physical and tougher team".

The two sides meet again in Game 5 in Philadelphia on Wednesday.

Brooklyn Nets stars Kyrie Irving and James Harden will both miss Game 5 of the Eastern Conference semi-finals against the Milwaukee Bucks due to injury.

Irving sprained his right ankle in the Nets' 107-96 loss in Game 4 on Sunday and underwent an MRI which confirmed he would not be available for Tuesday's clash, with the NBA playoff series in tied at 2-2.

Nets guard Irving joins former MVP Harden on the sidelines, with the latter still absence because of a hamstring he re-injured in Game 1.

Brooklyn head coach Steve Nash said the length of Irving's absence remains unknown.

"I have to wait and see how it progresses, I think," Nash said.

"And then the experts would have to wait and see how it progresses and give you a clearer picture on what the window would be for his return."

Nash added that Harden was "working out right now" but was unclear on his return to play timeframe.

The second-seeded Nets – eyeing their maiden championship – have battled injuries throughout the 2020-21 campaign, with Harden missing 21 games late in the regular season due to his troublesome hamstring.

"It's tough to lose great players but we've lost guys all season," Nash said. "If there's any silver linings, it's that we've continued to win games regardless of who's been available.

"We've been able to adapt on the fly which is difficult to do sometimes. That's something we have some experience with. We should have some comfort and belief."

The absence of two-thirds of the 'Big Three' puts a heavy burden on Kevin Durant, although Nash insisted it was not just about him.

"This does not fall on Kevin, this falls on the Nets," Nash said. "We've got to find a way together to play great basketball on both ends of the floor. We've proven we can do it.

"We try to stick to our principles and fundamentals, which is connectivity, competitive spirit, embracing the opportunity and playing together as a team."

There will be capacity crowds for the Wimbledon finals next month and around 45,000 people are set to be allowed into Wembley for the Euro 2020 semi-finals and final.

Prime Minister Boris Johnson on Monday announced a four-week delay in lifting coronavirus lockdown restrictions in England to July 19 due to rising cases of the Delta variant.

However, Wimbledon and the European Championship are being treated as test events, so there is set to be a full house of 15,000 on Centre Court for the championship matches on the weekend of July 10-11.

The grass-court grand slam will be the first outdoor sporting event to have a capacity crowd since the start of the pandemic.

When the tournament, which was not staged last year due to the COVID-19 crisis, starts on June 28 it will be at 50 per cent capacity.

A statement from the All England Club said: "We are pleased to have worked closely with the government, public health bodies, and our local authority in Merton, to confirm that, as part of this next phase of pilot events, The Championships 2021 will begin on Monday 28 June with 50 per cent capacity across the Grounds, building to full capacity crowds of 15,000 on Centre Court for the finals weekend.

"This will enable us to fulfil our aspiration of staging the best Wimbledon possible within the current circumstances, with the health and safety of all those who make Wimbledon happen - our guests, competitors, members, staff, media, officials, local residents, and partners - remaining our highest priority."

Crowds for England's first two Euro 2020 group games at Wembley have been capped at 22,500, but that figure is expected to be doubled so the stadium is half full for the semi-finals and final.

The semi-finals will be staged on July 6 and 7, with the final held on July 11.

Culture Secretary Oliver Dowden said: "We want to gather further evidence on how we can open up all big events safely, and for good.

"The expansion of trials of the NHS app and lateral flow testing will mean that bigger crowds will be able to attend a limited number of major sporting and cultural events early this summer as part of our events research programme.

"In the next few weeks, this means more fans enjoying the Euros and Wimbledon, and some of our biggest cultural and sports events."
