The one-year postponement of the Copa America gave Argentina vital time as they sought to avoid squandering probably the most precious asset ever granted to any international team in football history.

A yawning gap remains in Lionel Messi's glittering collection of honours. At club level, the Barcelona superstar has won it all, won it again and won it some more just for good measure. For Argentina, he is yet to lift a major honour.

Rather than an international tournament, Messi spent the last close-season negotiating his next move – which ultimately meant staying in Catalonia. His contract is up again in 2021, but the legendary forward must also negotiate the rearranged Copa this time.

Realistically, this tournament and the 2022 World Cup in Qatar represent his final shots at glory for La Albiceleste, with the nagging sense his best chance to emulate the likes of Pele and Diego Maradona with a defining triumph at the highest level might already have passed him by.

THE GOLDEN GENERATION

Over recent years, Messi has frequently appeared wearied as a man carrying the weight of his team on his shoulders for club and country.

Of course, this was not always the case. At Barcelona he was the shimmering jewel in Pep Guardiola's slick and sublime masterpiece before starring as part of Luis Enrique's turbo-charged MSN forward line.

Argentina's more forlorn efforts of late make it easy to forget what a defining generation of talent Messi once spearheaded.

Any heavyweight football nation collecting back-to-back Olympic gold medals, as Argentina did in 2004 and 2008, would reasonably expect the senior honours to follow – with or without arguably the greatest of all time at their disposal.

Names from those podiums in Athens and Beijing trip off the tongue. Javier Mascherano, Carlos Tevez, Javier Saviola, Pablo Zabaleta, Fernando Gago, Ever Banega, Ezequiel Lavezzi, Angel Di Maria and Sergio Aguero are all Olympic champions.

At the 2010 World Cup, the fairytale combination of Messi and the Messiah – the late Maradona inimitably entertaining but evidently ill-cast as head coach – fell to Germany in the quarter-finals.

Die Mannschaft also beat them in 2014 – this time as Mario Gotze scored the only goal in the final during extra time. Alejandro Sabella's steadying hand brought them to the brink of sporting immortality and Messi was named player of the tournament, despite some underwhelming showings by his own standards.

NEAR MISSES, RETIREMENT AND SHAMBLES

Gerardo Martino managed not to win a major trophy when he led Barcelona in 2013-14 and, unfortunately for Messi, history repeated during his tenure with the national team.

Gonzalo Higuain missed a glorious chance in the World Cup final and he and Banega erred from the spot as Chile won the 2015 Copa America in a penalty shoot-out.

Against the same opponents at the Copa America Centenario 12 months later, Messi himself failed amid further heartache from 12 yards.

As emotions ran high in the aftermath, the number 10 announced his retirement from international football, with rumours other stars would follow suit due to disaffection with the Argentine Football Association.

By the time Messi returned for a 3-0 World Cup qualifying defeat to Brazil that November, Edgardo Bauza's tenure as head coach was already on the rocks.

Jorge Sampaoli replaced him and Argentina needed an utterly majestic hat-trick from their talisman away to Ecuador to snatch a place at Russia 2018.

Perhaps they shouldn't have bothered.

Having brought Argentina to their knees while in charge of Chile, Sampaoli inadvertently did the same again during a shambling turn ended by eventual champions France in the last 16. There was a near revolt after a group-stage thrashing from Croatia and the coach left with his reputation in tatters.

LIONEL, LIONEL AND LAUTARO

Star names such as Martino and Sampaoli not working out probably help the cause of the unheralded Lionel Scaloni, who emerged from the rubble of Russia to take temporary and then full charge.

The 2019 Copa America got off to a similarly inauspicious start, but they scrambled out of the group and were arguably a little unlucky to lose 2-0 to hosts and eventual winners Brazil in the semis.

A feisty third-place match against Chile was won 2-1 thanks to goals form Aguero and Paulo Dybala, despite Messi bizarrely getting sent for being repeatedly butted by Gary Medel.

An indignant post-match interview brought a four-game ban, although a more vocal Messi leading through words as well as deeds was a pleasing development. In his absence, 4-0 and 6-1 wins over Mexico and Ecuador suggested brighter times ahead with a younger core.

Goals in the early stages of World Cup qualifying this season have been slightly more sparse – six in four games – but Argentina have still taken 10 points to remain unbeaten, second to Brazil in the standings.

Lautaro Martinez has been involved in half of those qualifying goals (two goals, one assist) and has now firmly established himself as the number one option at centre-forward, where Argentina's surplus of riches makes their lack of reward so embarrassing.

Going slightly further back, since Scaloni first took charge, the Inter star has 11 goals in 20 games – averaging one every 120.3 minutes and outstripping his expected goals (xG) figure of 7.8. Messi has six goals at 193.7 minutes per goal from an xG of 8.0 over the same period.

European club form coming back home to the national team has not always been a given during the Messi years, as evidenced by that slightly more ordinary return, so it is encouraging to see Martinez scoring at a faster rate under Scaloni than he has to date during his 100-game Serie A career (37 goals at one every 172.4 minutes).

THE NEW GENERATION

Aguero – a regular until Martinez came to the fore – may still have a role to play in trying to right a journey of heartache he has charted alongside Messi in blue and white. But Scaloni has come to rely on new faces as he quietly shapes a team in his own image. Moulding the ramshackle embarrassment of three years ago into a compact and hard-working unit necessitated high-profile casualties.

A pair of substitute appearances in November were Di Maria's first international outings since being dropped during the Copa. Paulo Dybala is fit again but seemingly now no longer even a bench option in the coach's eyes.

Argentina's all-action midfield creator is now Udinese's Rodrigo de Paul, whose 122 completed dribbles led Serie A this season, while his 18 goal involvements (nine goals, nine assists) ranked joint-third among midfielders.

Di Maria's Paris Saint-Germain colleague Leandro Paredes has started alongside De Paul in each qualifier to date, and Giovani Lo Celso has two assists in just 159 minutes of international action this season.

Disappointingly, winger Nicolas Gonzalez has been dogged by thigh injuries since scoring twice in November. With a goal every 155.8 minutes in the Bundesliga this term, he had been one of those set to profit from the Copa's new date.

Selection has also been consistent in defence this season, but German Pezzella's ill-timed injury absence meant Lucas Martinez Quarta was the Fiorentina defender allowed to settle in the heart of the back line.

Pezzella – a stand-in captain for the national team not so long ago – remains the main man in Florence, playing 32 league games to Martinez's 21, yet his younger colleague averages more tackles (1.9), interceptions (2.4) and blocks (0.6) per 90 minutes.

It looks like a case of either/or next to Nicolas Otamendi and his frequent reversions to slapstick, although Atalanta duo Cristian Romero and Jose Luis Palomino are also both now in the mix.

Elsewhere, despite the new call-ups – Emiliano Buendia is another debut option but has been plying his trade in the Championship – Scaloni's reliance on a steady XI might hint at a lack of depth. When the Copa was delayed by 12 months, one of world football's heavyweights might have hoped for more than the development of Inter's second-best striker and a wealth of defensive options in the meantime.

Instead, the narrative remains frustratingly familiar: Argentina need Messi to fire.

Inter midfielder Arturo Vidal is isolating in hospital after testing positive for COVID-19.

The 34-year-old returned a positive test while with the Chile national team and looks set to miss the upcoming World Cup qualifiers against Argentina and Bolivia as a result.

La Roja sit sixth in the CONMEBOL qualification standings, two points behind fourth-placed Paraguay in the final automatic spot.

Vidal's participation in the Copa America, which kicks off on June 11, will not be in doubt should he recover as expected.

The Football Federation of Chile revealed the midfielder's diagnosis came after he was struck by a bout of tonsillitis.

A statement on the national team's official website said: "The medical staff of the Chilean national team point out that at the request of Arturo Vidal, it is announced that he was diagnosed in the daily preventive examination with positive COVID."

Posted on Monday evening, the statement added: "Arturo has been hospitalised and isolated from the group for more than 72 hours in a preventive measure indicated by the medical team, due to the presence of previously reported severe pleural tonsillitis, corroborated by specialists in infectious and respiratory diseases and with negative PCR controls.

"It is noted that all the rest of the delegation is with negative PCR today in accordance with health protocols."

In a post on his Instagram page, Vidal shared his belief that he had caught COVID-19 from a friend who had carried the virus without showing symptoms.

Chile will continue carrying out regular tests in order to ensure that one infection does not result in an outbreak.

Vidal joined his national team off the back of a successful season in which he helped Inter win the Serie A title under Antonio Conte.

Egan Bernal hopes to complete a Grand Tour clean sweep at the Vuelta a Espana after winning the Giro d'Italia.

The INEOS Grenadiers rider sealed a first Giro title in Milan on Sunday, winning by a margin of a minute and 29 seconds.

Bernal will not go in search of a second Tour de France crown this year, but is eyeing a maiden Vuelta success in a race that will start on August 14.

The Colombian told Semana TV: "Yes, the Vuelta. Right now, I don't want to think about one month training and being away from home, but I like to race, and I like to prepare, to do things well, so I know I will have the motivation to go to the Vuelta and do it well.

"We're looking at the Vuelta. I can't just sit at home and do nothing."

Bernal said he has matured since winning the Tour two years ago.

"I've lived a lot of things, not just in sport but at the personal level as well," he added.

"Things are changing, and I am more mature. I won the Tour at 22, and that's not easy. I obviously had a lot to learn, and I still do. I've changed a lot since I was 22, and the Egan at 22 is very different than the Egan of today.

"I don't think I could have won this Giro if I had faced the same situation at 22. I'm only 24 now, so I am not that old, but a lot of things have happened since then, and it helped me to win this Giro. I was surrounded by good people with a lot of experience."

Bayern Munich star Robert Lewandowski has hit out at the demands placed on footballers in the modern era, insisting the schedule players face in the coming years poses a "big problem".

The Pole has made 46 appearances for club and country over the course of a 2020-21 campaign condensed by the coronavirus pandemic, and is set to add to that at Euro 2020.

The coming years are unlikely to be any easier, with a mid-season World Cup in Qatar coming up in 2022 and Champions League reforms set to add an extra four group games from 2024.

And Lewandowski is concerned that players are at risk of burnout as the demands on their bodies continue to build.

"So many people forget we're humans, we're not machines, we cannot play every day at the highest level of performance," he told The Times.

"For football and for young players, that will be the big problem, to stay at the top for many years, because now and maybe the next two years, that will be extreme: so many big games."

Lewandowski top scored with 15 goals as Bayern won the Champions League for the first time in seven years in 2019-20.

But he thinks the addition of extra fixtures to Europe's premier cup competition could ultimately ruin the spectacle for supporters.

"Even for the fans, I think so many games will be more boring because if you wait for the games longer, there's more expectation, that feeling that you've been waiting for this," he added.

"The quality of games will go down. It's not possible to stay with this quality on the top with so many games."

Lewandowski's own form showed no sign of fading amid the 2020-21 schedule as he broke Gerd Muller's long-standing Bundesliga record for goals scored in a single season with his 41st top-flight strike of the campaign in Bayern's win over Augsburg.

Manchester United forward Mason Greenwood has withdrawn from England's provisional squad for Euro 2020 due to injury.

United on Tuesday revealed that Greenwood would not be in Gareth Southgate's party for the upcoming tournament due to an underlying problem that also kept him out of the Under-21 European Championship in March.

The announcement came on the day that Southgate will cut his squad from 33 to 26 players.

United stated on their official website: "Manchester United striker Mason Greenwood has withdrawn from the provisional England Euro 2020 squad, in order to recover fully from an underlying injury that also kept him out of the Under-21 European Championship in March.

"Mason's club appearances were managed carefully to maintain his availability through the intensive 2020/21 Premier League and Europa League schedules.

"But a further spell of tournament football would not be beneficial and Mason will remain at Manchester United to recuperate and prepare for pre-season training."

Memphis Grizzlies coach Taylor Jenkins insisted only the finest of margins separate his team from the NBA's best after a 120-113 loss to the Utah Jazz in Game 4 of their playoff series.

Donovan Mitchell had 30 points and eight assists to lead the top-seeded Jazz to the brink of the conference semi-finals.

The Jazz survived another spirited effort by the eighth seeds to take a 3-1 series lead and can advance with a win in Game 5 on Wednesday. 

But Jenkins believes the Grizzlies are still in with a shot.

"We are right there," Jenkins said. "We are literally going toe-to-toe with the best team in the NBA.

"We are doing a lot of things great. We gotta find ways to do more. 

"This season isn't over."

Ja Morant scored 23 points and had 12 assists but made just one of seven three-pointers for Memphis, who were 10 of 35 from distance as a team. 

Jenkins acknowledged that, while the Grizzlies fell short in some areas, they were close to perfection.

"You are never going to play a perfect game," he said. "We have to play a perfect game against this team, and we are so close.

"Two games in a row it comes down to the last couple of minutes. I would not say I am frustrated. I am so encouraged.

"All we gotta do is go and win one game on the road. We have won there before.

"Our mentality all season long is to continue to fight, be the most competitive team, the most together team.

"I have the utmost faith in this group that when we go out and get on a plane tomorrow, we will be ready for Game 5."

A hectic, congested year of football culminates in the delayed European Championship, which starts on June 11 when Turkey take on Italy in Rome.

Euro 2020, hosted in 11 cities spread across the continent, was meant to be a celebration of the 60th anniversary of UEFA's international tournament. Instead, the coronavirus pandemic derailed the plans, forcing the postponement of the event until 2021.

Though the qualified teams had been readying themselves to play last year, and the pandemic has forced a much-altered football calendar in 2020-21, some countries may have benefitted from the delay.

For others, it may be a case of what might have been. Here, using Opta data, Stats Perform looks at how the main favourites to go all the way have been boosted by the postponement. 

Belgium

Romelu Lukaku – Belgium's record scorer – has built on a brilliant debut season with Inter, going on to help the Nerazzurri claim the Scudetto, with the 28-year-old netting 24 times in Serie A (a tally bettered only by Cristiano Ronaldo), at an average of one goal per 120 minutes, and providing 11 assists in the process.

Another player who has gone from strength to strength in 2020-21 has been Youri Tielemans, who lashed in an exceptional strike to win Leicester City's first FA Cup. The midfielder racked up 4,438 minutes of playing time, the sixth-highest total in Europe's top five leagues, so Roberto Martinez – whose future is uncertain – may have to manage him carefully.

England

Gareth Southgate named a 33-man provisional squad, and while the England boss does have doubts over the fitness of some key stars, he cannot complain at the wealth of talent at his disposal, with several players having come to the fore in the last year.

John Stones is back to his best, and right-backs Kyle Walker and Kieran Trippier have won titles in England and Spain respectively. Ahead of them, Jude Bellingham – who could become the youngest Three Lions player to appear at the Euros – had an outstanding season with Borussia Dortmund, though it is in attack where Southgate really is spoilt for choice.

Harry Kane won the Premier League golden boot and topped the assist charts, while back-up Dominic Calvert-Lewin registered a top-flight goal every 179.63 minutes. Behind them, Phil Foden and Mason Mount are talismanic figures Champions League finalists City and Chelsea, while Jack Grealish created 81 chances – the third highest in the division – for Aston Villa, despite missing 12 games through injury. 

France

England's options somewhat pale in comparison to the depth Didier Deschamps has to play with. Eduardo Camavinga looked set to be one of the youngsters to break onto the scene for Les Bleus, but the Rennes teenager has not even made the squad for the rearranged tournament, while Anthony Martial is another big name to miss out.

Kylian Mbappe reached last season's Champions League final and has gone on to score 42 goals in 47 appearances across all competitions this term, averaging a strike every 89 minutes, while Antoine Griezmann is looking sharp.

As if it was not enough, Deschamps has also recalled Karim Benzema, who scored 30 goals in all competitions for Real Madrid to earn his first call up in over five years. In midfield, N'Golo Kante has been spectacular for Champions League winners Chelsea, with only six Premier League midfielders who have attempted over 75 tackles recording a higher success rate than his 53.16.

Germany

Joachim Low has decided to call it quits after the tournament, with Hansi Flick incoming. But surely that will only spur Germany on as they look to end Low's tenure on a high, and he has recalled 2014 World Cup winners Thomas Muller and Mats Hummels to help the cause.

With Timo Werner having struggled to convert chances into goals for Chelsea – scoring 12 times in 52 appearances and registering a shot conversion rate of just 7.59 in the Premier League – Muller, who created the most chances (93) and provided the most assists (18) in the Bundesliga – will share the burden, while Jamal Musiala, Bayern Munich's youngest Champions League goalscorer, is surely one of the youngsters to watch.

Italy

After failing to qualify for the 2018 World Cup, Italy were in need of a rebuild, and Roberto Mancini has provided the steady hand required.

Mancini is unbeaten in all 26 games of his Italy tenure, as he closes in on the all-time record of 30 set by Vittorio Pozzo in the 1930, and the Azzurri look well placed to challenge. One question mark could be over goalkeeper Gianluigi Donnarumma, who seems destined for a move to Juventus.

Netherlands

Perhaps no team has undergone more change in the past year than the Netherlands. Ronald Koeman looked set to have a strong side heading into Euro 2020, albeit injuries would have shorn him of Memphis Depay and Donyell Malen.

As luck would have it, both of those attackers will be fit for the Oranje, and come in off the back of strong seasons with Lyon and PSV respectively. But it will not be Koeman who is in charge – he is of course now at the helm at Barcelona, though whether his tenure continues for much longer remains to be seen – with Frank de Boer his replacement.

Portugal

More records tumbled in 2020-21 for Ronaldo, though there is no doubt the 36-year-old's powers are waning slightly with age.

Portugal are, of course, the holders, having seen off France in 2016, but Fernando Santos' squad is arguably much stronger than it was five years ago, with Andre Silva – who finished behind only Robert Lewandowski in the Bundesliga scoring charts this season – providing a focal point up top, while Bruno Fernandes, Diogo Jota and Joao Felix have continued their trajectories of improvement in the last year.

But it is Ruben Dias' form over the last season that may benefit Portugal the most. The centre-back has been imperious for Man City, playing a crucial role in a defence that has conceded just 42 goals in all competitions.

Spain

With Sergio Ramos not judged to be fit, Luis Enrique has picked a relatively inexperienced – at least at international level – defence, with only 24 players named in his squad.

Pau Torres is certainly a player who has improved over the past 12 months. He has just helped Villarreal to a Europa League triumph, with the centre-back, who is sure to be interesting some of Europe's biggest clubs, being the defender with the most games played in the competition without being dribbled past (nine). Spain have also been buoyed by Aymeric Laporte's switch of allegiance from France.

Thiago Alcantara has not always hit his best form at Liverpool, though Spain's midfield is boosted by two title winners in Atletico Madrid duo Koke and Marcos Llorente, who was involved in 23 goals in 2020-21.

Up top, Gerard Moreno netted 30 goals in all competitions for Villarreal – among LaLiga players, only Lionel Messi played a part in more goals.

The Washington Wizards have shown their confidence in Rui Hachimura from the very beginning, and he rewarded them Monday with one of the best games of his career. 

Hachimura scored 20 points on eight of 12 shooting from the field and grabbed 13 rebounds to play a key role in the Wizards' 122-114 victory over the Philadelphia 76ers in Game 4 of their playoff series. 

Though the 23-year-old forward from Japan has started every game he has played for Washington in his two NBA seasons, his performance Monday had his team-mates and head coach Scott Brooks raving. 

"He's growing up right in front of our eyes. Sometimes I want these guys to be 27 right now and four seasons of playoff experience, but you get it by going through it," Brooks told reporters. 

"He was a big, big part of us on both ends of the floor. He's a multi-defender, he can guard many different types of player, and we need his rebounds. We can't just rely on our point guard getting rebounds. 

"He was good on guarding, he was good on making shots. He had a big three and had a big defensive possession not too far from one another."

Hachimura had a pair of key baskets late in the game, capped by a three-pointer off a pass from Bradley Beal that gave Washington a six-point lead over the top-seeded 76ers with 45.8 seconds to play. 

"It was a great pass by Brad. ... He trusted me and he passed to me, so I had to shoot with confidence," Hachimura said. "That was a big three for sure, especially at this moment.

"I was just trying to be aggressive on both ends, defensively and offensively. As a team I think we played together tonight, and that's why we got a win."

Getting contributions from players beyond the star back-court of Beal and Russell Westbrook is critical to the Wizards' chances, and Hachimura was the player who stepped up for Washington's first win in the series. 

After logging 27 and 26 minutes the previous two games, he played 41 Monday, making himself indispensable on both ends of the court. 

"For me, we always just want him to be aggressive and accept his challenges on the defensive end," Beal said. "That's when he has a good game, when he's locked in on defence, he's guarding somebody, he's making it tough on them, he's guarding Ben [Simmons], making it tough on him.

"Then he rebounded the ball really well tonight, too. I think him just being engaged in all facets of the game kind of propelled him on the offensive end and boosted his confidence. Once he seen one [shot] go in, he was making them all night." 

The key going forward is for Hachimura to play this way more consistently, but his coach liked what he saw in Game 4. 

"We're all trying to figure things out, with Rui and with everybody," Brooks said. "This has been a season of figuring it out on the fly at times, but when Rui gets that gear, that's what we need.

"He's had it, it's been choppy at times through some of his unfortunate injuries and safety protocol. He seems to ramp up and then something unfortunate takes place. But he's in a good place."

There is no margin for error in the top-heavy National League (NL) West, and the Los Angeles Dodgers kept the pace Monday with an impressive 9-4 win over the St Louis Cardinals. 

Trevor Bauer surrendered three home runs in a game for the first time since July 13, 2019, but the defending World Series champions got enough timely hitting to prevail. 

Chris Taylor led the way with three hits for Los Angeles, including the second of back-to-back home runs along with Gavin Lux to give the Dodgers a 2-0 lead in the second inning. 

But the real highlight for Taylor came in the sixth, when he capped a remarkable 14-pitch at-bat against Genesis Cabrera with a three-run double that gave Los Angeles a 6-3 lead. 

The Dodgers gained a game on the San Diego Padres with the win and sit two back of the rival San Francisco Giants for the division lead. 

Rays finish May on fire

The Tampa Bay Rays may be sad to see May come to an end, as their 3-1 victory against the New York Yankees gave them a 35-20 record to finish the month after a 13-14 start to the season. According to Stats Perform, they are the first MLB team to be under .500 at the beginning of a month and at least 15 games over at the end since the Boston Braves did it in August of 1933.

Making his first start for the Chicago Cubs, Kohl Stewart shut down the powerful Padres line-up for five innings, allowing three hits and one unearned run, as the Cubs rolled to a 7-2 win that moved them past the Cardinals and into first place in the division. 

The Houston Astros closed in on the Oakland Athletics in the American League (AL) West with an 11-2 pounding of the Boston Red Sox, the hitters backing a strong outing by Jose Uquidy. 

Orioles come up empty again

The Baltimore Orioles took the Minnesota Twins to extra innings but fell once again, 3-2 in the 10th, for their 14th defeat in succession. On the plus side, the Orioles have a long way to go before matching their club-record losing streak of 21 in a row to open the 1988 season. 

While the Arizona Diamondbacks managed to break their lengthy losing streak Sunday, a 6-2 defeat to the New York Mets on Monday gave them a 5-24 record in May as the month came to a close.

Two-way heroics for deGrom

Jacob deGrom was his usual dominant self on the mound against the woeful Diamondbacks, allowing two hits and striking out eight in six scoreless innings to lower his ERA to 0.71, but the Mets star also demonstrated his abilities at the plate with a run-scoring single. According to Stats Perform, deGrom is the only pitcher since ERA became an official stat in 1913 to have a sub-1.00 ERA and a batting average of at least .450 over any span of eight starts with a minimum of 10 plate appearances. 

Monday's results

Tampa Bay Rays 3-1 New York Yankees
Minnesota Twins 3-2 Baltimore Orioles
Cincinnati Reds 11-1 Philadelphia Phillies
Milwaukee Brewers 3-2 Detroit Tigers
Chicago Cubs 7-2 San Diego Padres
Chicago White Sox 8-6 Cleveland Indians
Cleveland Indians 3-1 Chicago White Sox
San Francisco Giants 6-1 Los Angeles Angels

Seattle Mariners 6-5 Oakland Athletics
Atlanta Braves 5-3 Washington Nationals
Kansas City Royals 7-3 Pittsburgh Pirates
Los Angeles Dodgers 9-4 St Louis Cardinals
New York Mets 6-2 Arizona Diamondbacks

Rays at Yankees

Domingo German will get the ball for the New York Yankees (29-25) as they attempt to end a four-game losing streak against Tyler Glasnow and the seemingly unstoppable Tampa Bay Rays (35-20), who have won 16 of their last 17 games.

Another day brought another worrying incident involving fans at NBA playoff games. 

A man ran onto the court with about four minutes remaining in the third quarter of the Washington Wizards' 122-114 win against the Philadelphia 76ers in D.C. on Monday.

The man jumped and attempted to touch the backboard while players from both teams came down court from the opposite end before a security officer at Capital One Arena tackled him as referees stopped play. 

Monumental Sports and Entertainment, the company that owns the Wizards and the arena, said the fan would be banned from future events and the organisation would pursue charges against him with D.C. police. 

"Monumental Sports & Entertainment has a zero tolerance policy when fans violate our code of conduct at Capital One Arena," the company said. 

The incident came a day after a fan in Boston threw a water bottle at Brooklyn Nets star Kyrie Irving, leading the veteran to deplore players being treated as if they are "in a human zoo."

That followed episodes in which Wizards guard Russell Westbrook was showered in popcorn during a defeat away to Philadelphia in Game 2, while a New York Knicks fan spat on Atlanta Hawks star Trae Young in Game 1.

"Fans got to grow up at some point," Nets star Kevin Durant said Sunday. "I know that being in the house for a year and a half with the pandemic got a lot of people on edge, got a lot of people stressed out, but when you come to these games, you have to realise these men are human.

"We are not animals; we are not in the circus. You coming to the game is not all about you as a fan. So, have some respect for the game. Have some respect for the human beings, and have some respect for yourself. 

Joel Embiid left Game 4 of the Philadelphia 76ers-Washington Wizards NBA playoff series early due to a right knee injury. 

The Philadelphia star landed awkwardly after driving to the basket for a shot attempt with just under five minutes to play in the first quarter Monday.

Embiid remained in the game until 36.5 seconds remained in the period, then walked up the tunnel to the locker room. 

He did not return to the court, and the team announced at the start of the second half that he would miss the rest of the game with right knee soreness. 

Philadelphia led by as many as 11 before Embiid's injury, but their fortunes began to fade when he went out and the Wizards took their first lead of the game just before half-time. 

While Philadelphia has a comfortable 3-0 series edge, they will not want to be without Embiid for an extended period. 

Their star made 14 of 18 shots from the field in scoring 36 points in Game 3. 

He had eight points and six rebounds before departing Monday.

After fighting through a knee injury to start Sunday's game, Los Angeles Lakers star Anthony Davis is in question for Game 5 against the Phoenix Suns. 

Davis injured his groin just before halftime of Game 4 and missed the second half of the Lakers' 100-92 loss that levelled the series at 2-2. 

Head coach Frank Vogel told reporters Monday that scans confirmed Davis suffered a strained groin. 

Davis as questionable for Tuesday's game in Phoenix, but Vogel said the eight-time All-Star will do everything he can to ensure he is on the court. 

"I mean, these guys, they're great competitors," Vogel said. 

"They're always going to say, 'I'm ignoring this. I'm going to be in there.' So, we'll just see.

"That's what his mindset is, like any competitor, but we'll see what the groin feels like tomorrow and we'll make a smart decision. But he's in good spirits."

Davis previously hurt his knee in Game 3, though he continued to play, and vowed to reporters that there was "no chance" he would miss the next game. 

The severity of his latest injury is unclear, but little-used forward Markieff Morris tweeted the word "opportunity" Monday, indicating he sees a chance for some court time after playing only 12 minutes in the first four games. 

Vogel declined to say what his plans might be should Davis not be able to play Tuesday. 

On the positive side, Vogel said he was "hopeful" guard Kentavious Caldwell-Pope will return to the lineup after missing Game 4 with a knee injury. 

Naomi Osaka's shock withdrawal from the French Open generated an outpouring of support across the tennis world and beyond. 

The four-time grand slam winner pulled out of Roland Garros on Monday, a day after tournament organisers said her continued refusal to attend mandatory press conferences could result in her being thrown out of the event.

Osaka said in a statement posted to social media that she has had bouts of depression since winning the US Open in 2018 and never intended for her stance to become a distraction. 

Monday's action in Paris had mostly been completed when the news broke, but Serena Williams shared her thoughts following an evening match. 

Williams acknowledged feeling anxious dealing with the press at times early in her career, but said she believed the experience made her stronger. 

Top of mind, however, was concern for Osaka. 

"The only thing I feel is that I feel for Naomi. I feel like I wish I could give her a hug because I know what it's like," Williams said.

"We have different personalities, and people are different. Not everyone is the same. Everyone is different and everyone handles things differently.

"You just have to let her handle it the way she wants to, in the best way she thinks she can, and that's the only thing I can say. I think she's doing the best that she can."

Osaka's fellow players and others took to social media with encouraging messages for the 23-year-old. 

Venus Williams wrote on Instagram: "So proud of you. Take care of yourself and see you back winning soon!"

Young American star Coco Gauff responded to Osaka's tweet by writing "stay strong ... I admire your vulnerability." 

A pair of tennis legends also weighed in on Twitter. 

"I am so sad about Naomi Osaka. I truly hope she will be ok," Martina Navratilova wrote.

"As athletes we are taught to take care of our body, and perhaps the mental and emotional aspect gets short shrift.

"This is about more than doing or not doing a press conference. Good luck Naomi - we are all pulling for you!"

Billie Jean King added: "It’s incredibly brave that Naomi Osaka has revealed her truth about her struggle with depression. Right now, the important thing is that we give her the space and time she needs. We wish her well."

Mardy Fish, the former ATP player who reached number seven in the world, wrote to Osaka: "Mental health is nothing to criticise. Nothing to joke about. Pls [sic] take your mental health seriously. Without my support system, I truly believe I would not be here today. Here for you."

That public show of support extended beyond tennis, as prominent NFL and NBA players praised Osaka for her courage. 

"We are with you," said Seattle Seahawks quarterback Russell Wilson.

NBA star Stephen Curry wrote: "You shouldn't ever have to make a decison like this - but so damn impressive taking the high road when the powers that be don't protect their own. Major respect."
