Simone Biles said she had put her "mental health first" after missing out on adding a fifth Olympic gold medal to her collection following an early withdrawal from the women’s team final.

The 24-year-old gymnastics icon revealed she was “dealing with things internally” after a disappointing performance on the vault.

Biles posted the lowest score of the first rotation on Tuesday as she landed awkwardly after failing to execute an Amanar, while only completing a Yurchenko 1.5 twist.

After she subsequently withdrew, Team USA had to settle for a silver medal behind the Russian Olympic Committee while Great Britain completed the podium.

Biles admitted that she was "fighting demons", explaining: "I just don't trust myself as much as I used to. I don't know if it's age. I'm a little bit more nervous when I do gymnastics. I feel like I'm also not having as much fun."

She added: "I say, 'put mental health first'. Because if you don't, you won't enjoy sport and won't succeed as much as you want to.

"So it's okay sometimes to sit out the big competitions to focus on yourself, because it shows how strong a competitor and person that you really are, rather than just battling through it."

OSAKA STUNNED

The big names continue to tumble in the women’s singles tennis event, with second seed Naomi Osaka defeated in straight sets.

The home favourite, who lit the Olympic cauldron on Friday, was denied a place in the quarter-finals after being ousted 6-1 6-4 by world number 42 Marketa Vondrousova.

This event marked Osaka’s first competitive tennis in two months since her early withdrawal from the French Open at the end of May, citing mental health issues.

The world number two is the latest of the big names to fall at the Tokyo Games, with top seed Ash Barty and third seed Aryna Sabalenka also suffering early exits.

"Of course, it's one of the biggest wins of my career," Vondrousova said. "Naomi is a great player, so I knew it would be a tough match. 

“I'm very happy with my play. I played amazingly in the first set, and then the second set was really tough. I'm just happy to be through."

ARGENTINA RECOVER TO SEE OFF SPRINGBOKS

Argentina recovered from a dreadful start to beat South Africa and book their place in the rugby seven semi-finals.

Trailing 7-0 after just under two minutes, the Pumas were then reduced to six men when Gaston Revol - who was reduced to tears - was shown a straight red card.

Nevertheless, they demonstrated tremendous resilience and character before eventually running out 19-14 winners.

Argentina will play Fiji in the last four after the reigning Olympic champions swept Australia aside 19-0.

Great Britain stormed back from 21-0 down to beat the USA, scoring four tries to secure a dramatic 26-21 victory.

Team GB will play New Zealand, who eased to a 21-10 success over Canada.

Massimiliano Allegri revealed he turned down Real Madrid in favour of a second spell with Juventus.

Allegri was appointed as Bianconeri boss in May after Andrea Pirio was relieved of his duties following a poor season, ending with the club only fourth in Serie A.

The experienced Allegri led the Turin giants to five consecutive Serie A titles, four Coppa Italia triumphs and two Champions League finals during his previous tenure.

Allegri, 53, on Tuesday revealed he could have taken over at Madrid before Carlo Ancelotti was appointed as head coach.

"I have to thank Real Madrid and the president for the opportunity he gave me [to coach Real Madrid]. Then I thought about it and chose Juventus," Allegri said during his presentation news conference.

"It was a gesture of love for a club that gave me a lot and who I enjoy coaching."

Inter's 2020-21 Scudetto triumph ended Juventus' nine-year spell of dominance in Italian football and Juve president Andrea Agnelli is hoping Allegri can reassert the Bianconeri's authority.

"It’s useless to present him and repeat what he’s won once again. Perhaps, the streak of Serie A titles he’s won is something impossible to equal," Agnelli added at Allegri's unveiling.

"We analysed what Juventus could have been with the return of Allegri, we agreed that it could have been a risky choice for both of us because of his glorious past and the expectations that he would bring.

"What Juventus can give is the right environment to reach these results. Every victory has been achieved thanks to hard work. As Max has said many times, winning is not for everybody.

"A new season begins, our target is to be competitive for every trophy in March, then we’ll see. Max is the coach of Juventus for the next four years because he has the credibility to write an exciting new chapter."

The Juve president took a dig at former head coach Maurizio Sarri, who had claimed the 2019-20 Scudetto he won in Turin was taken for granted.

"Here at Juventus, we work hard every day to achieve victories," Agnelli continued.

"We can’t take victories for granted, whoever thinks that the trophies we’ve won over the last few years have been less appreciated is wrong because, behind every trophy and every season, there is a great commitment, sacrifice and desire to win."

Agnelli also confirmed Giorgio Chiellini, who captained Italy to their first European Championship triumph since 1968 at Euro 2020, will sign a contract extension with the club.

Federico Delbonis and Laslo Djere crashed out of the Generali Open in the first round on Tuesday.

Fifth seed Delbonis and sixth seed Djere were the highest-ranked players in action on day two, but both fell to surprise defeats.

Delbonis, a recent semi-finalist at the Hamburg European Open, was convincingly beaten 6-2 6-4 by Arthur Rinderknech.

Frenchman Rinderknech fired down 10 aces and was only broken once in the contest.

Djere, meanwhile, put up more of a fight but ultimately succumbed to Daniel Altmaier, who won 4-6 6-3 6-3 in a battle lasting two hours and 10 minutes.

World number 50 Djere had also made the semi-finals in Hamburg and followed that up with another run to the last four at the Swiss Open Gstaad.

But his run of form came to an end as German Altmaier – who himself enjoyed a semi-final run in Croatia last week – booked a last-16 tie meeting with Marco Cecchinato after breaking Djere on six occasions.

Cecchinato had beaten Radu Albot in straight sets to reach the next round while qualifier Jozef Kovalik saw off Jaume Munar with a 6-4 6-4 victory.

The top four seeds, including number one Casper Ruud, will begin their campaigns at the ATP 250 event in Kitzbuhel on Wednesday.

The second Twenty20 International of the series between Sri Lanka and India has been put back a day after Krunal Pandya tested positive for coronavirus.

Pandya was in the India team that won the first match by 38 runs in Colombo on Sunday, but the all-rounder returned a positive test ahead of the second game scheduled to take place on Tuesday.

The Board of Control for Cricket in India (BCCI) revealed eight members of the touring party were identified as close contacts with Pandya, so they have been forced into isolation.

Sri Lanka and India will instead contest the second game on Wednesday, with the third and final game of the series taking place on Thursday.

The BCCI revealed RT-PCR tests were undertaken to discover if there has been any further outbreak in the squad.

Simone Biles outlined the importance of athletes' mental health as she talked through her decision to sit out the women's team all-around final on Tuesday.

The gymnastics superstar's first final of the Tokyo Olympics attracted plenty of attention at the Ariake Gymnastics Centre, beginning a bid for a record-breaking six golds at one Games.

But the United States could only secure silver after Biles bowed out following her first routine.

Biles – the sport's premier performer – posted the lowest score of the first rotation (13.766) on the vault and immediately left the floor with a trainer.

Her absence from the remainder of the competition was confirmed by USA Gymnastics due to what the organisation said was a "medical issue".

But Biles opened up on the reasons for departure following the event, which was won by the Russian Olympic Committee.

Asked if she was injured, Biles said: "No, just my pride is hurt a little bit."

The 24-year-old added she was "fighting demons" and explained: "I just don't trust myself as much as I used to. I don't know if it's age. I'm a little bit more nervous when I do gymnastics. I feel like I'm also not having as much fun."

At a Team USA news conference, Biles offered a more positive message, following in the footsteps of Japan icon Naomi Osaka, who withdrew from a series of high-profile tennis events to preserve her welfare before representing her country in the Olympics on home soil.

"I say, 'put mental health first'," Biles said, asked if Osaka's stance was inspirational.

"Because if you don't, you won't enjoy sport and won't succeed as much as you want to.

"So it's okay sometimes to sit out the big competitions to focus on yourself, because it shows how strong a competitor and person that you really are, rather than just battling through it."

Biles would accept no credit for her team's medal, saying: "I didn't do my job, they came out and they stepped up.

"They did what they needed to do and more, last minute. This medal is all them and the coaches and it has nothing to do with me. They did it without me."

Giannis Antetokounmpo bucked the trend of exclusively high draft picks winning NBA MVP before Nikola Jokic took it to an entirely different level this past season.

As the 41st overall selection in 2014, Jokic became by far the lowest draft pick ever to win the award, surpassing Antetokoumpo and Steve Nash, who were both chosen 15th overall. Prior to Jokic and Antetokoumpo, the previous 10 MVPs were won by players picked between first overall (LeBron James, Derrick Rose) and seventh (Stephen Curry).

Jokic's MVP serves to further illustrate that big-time NBA talent can be found lower in the draft, and while most second round and undrafted players may not win any MVPs, they can still become regulars that make major contributions in the right situations.

This year's draft class has an elite first tier with the likes of Cade Cunningham, Evan Mobley and Jalen Suggs, yet it also boasts some solid depth, with potential gems lurking into the second round or later.

Here's a look at five players that could outperform pre-draft expectations:

KESSLER EDWARDS - Pepperdine

One look at Edwards' statistics during his three seasons at Pepperdine and improvement and versatility jump off the page. After averaging 10 points and 5.6 rebounds in his 2018-19 freshman season, Edwards went up to 13.8 with 7.5 boards the following year, followed by a breakout campaign with 17.2 points, 6.8 rebounds and a career-best 49.1 field-goal percentage in 2020-21. That also included an 87.6 free-throw percentage that ranked among the best in the nation.

He earned first-team all-WCC honours and was named CBI Tournament MVP after Pepperdine defeated Coastal Carolina for the title. Edwards was one of six Division I players this past season to average at least 17 points and 6.5 rebounds while also making 45 three-pointers.

Edwards proved to be consistent from deep with a 38.7 percentage (148-for-378) during his time with the Waves, and any 6ft 8" player that can score, rebound and connect from long range will draw the interest of NBA teams. Add in Edwards' length and high-level defence and a first-round pick would seem to be a guarantee, but he's expected to drop into the second round or possibly go undrafted, mainly because he didn't play at a Power Six school and the long-held belief is that facing lesser competition in college is a detriment at the next level.

One of the knocks on Edwards is a funky hitch in his shot that makes him look as if he's almost shot-putting the ball toward the basket. Maybe a team could alter his shooting style at some point but that should not prevent him from being drafted.

Even if his offensive game fails to develop - and that seems unlikely - Edwards shouldn't have a problem guarding multiple positions in the NBA. He is quick enough to stick with smaller guards and forwards and is lanky enough to cope with bigger post players as well.

 A minimal contributor off the bench would likely be where Edwards finds himself early in his NBA career, but he has enough upside as an on-ball defender with a developing perimeter game to potentially excel as a starter or regular rotation player in time.

JEREMIAH ROBINSON-EARL - Villanova

Robinson-Earl only spent two seasons at Villanova but received plenty of accolades in his brief tenure with the Wildcats. He was named Big East Freshman of the Year in 2019-20 and captured co-Big East Player of the Year honours this past season, leading the team with 15.7 points and 8.5 rebounds.

Jay Wright's program has produced a considerable amount of pro talent lately in Josh Hart, Saddiq Bey, Eric Paschall, Mikal Bridges and Donte DiVincenzo, with Robinson-Earl having an excellent opportunity to continue the Wildcats' success in the NBA.

While he does not project as a future All-Star due to average athletic ability, Robinson-Earl can do a lot of different things well and is a smart player with intangibles that NBA teams love to have on their roster. There may be other players with higher upsides that get drafted in the second round, but Robinson-Earl can score, rebound, guard multiple positions and plays with a relentless motor.

A more refined offensive game and the ability to shoot from long range more consistently would make Robinson-Earl a more appealing prospect, but he does have a soft touch and a smooth release from mid-range. He is comfortable playing low in the post, does not shy away from the physical side of the game and has great court vision with a knack for making the right play.

Much in the way that Draymond Green - a second-round pick himself - is utilised by the Warriors, Robinson-Earl could eventually fill a similar role for a team that has stars occupying other positions on the court.

JOE WIESKAMP - Iowa

Every year there are a few players that get a huge boost from the draft combine and chief among that group this season is Wieskamp. Before an impressive showing in Chicago, the Iowa sharpshooter was facing the possibility of going undrafted despite a stellar college career.

He averaged 14.8 points and 6.6 rebounds this past season and led all players in three-point accuracy, making 49.5 percent (51-for-103) of his attempts in Big Ten play in earning all-conference second team honours. Wieskamp was the only Division I player in the nation to total at least 400 points, 200 rebounds 70 three-pointers and 25 steals. He also made five three-pointers in six games in 2020-21, second most of any player from a major conference.

More than ever, teams are putting a premium on perimeter shooting and Wieskamp is among the best available in that department, as evidenced by his 41.2 percentage (184-for-447) from deep during his time at Iowa. At 6ft 7", he can use his size to take advantage of smaller defenders that get switched onto him and his mechanics are near flawless with a high release.

One knock on Wieskamp is his relative inability to create his own shot but as a good athlete with surprising jumping ability, he should be able to overcome that with experience at the next level.

Wieskamp has the skills and ability to provide instant offense off the bench and is the perfect floor spacer for today's game. His pure shooting stroke, combined with rebounding and defensive ability should make him a valuable contributor in the NBA for years to come.

JOSH CHRISTOPHER - Arizona State

Christopher is the classic story of a player whose stock drops due to an injury. Limited to just 15 games in his only season for Arizona State in 2020-21, the 6-foot 5, 215-pound guard is a high-risk, high-reward pick that has NBA athleticism with the ability to excel at both ends of the court.

A likely first-round selection before injuries and COVID protocols ended his season in February, Christopher's value took a hit, and he could fall into the middle part of the second round. That range is often the perfect time to take a gamble on an athletic player with skills that match well in the NBA, even if other parts of his game need work.

Christopher had a few exceptional games in his one college season, including a 28-point, 11-for-17 performance against then-No. 3 Villanova on November 26 in the championship game of the Empire Classic. That 28-point display was tied for the most points allowed by the Wildcats all season. Christopher ended up averaging 14.3 points, 4.7 rebounds and 1.5 steals, and while he only shot 30.5 percent (18-for-59) from 3-point range, he did connect on 12-of-27 over his final seven games.

Guards with size that can get to the basket are always in demand and that's what Christopher does best. He is quick with excellent jumping ability and doesn't have a problem finishing through contact. Whether in transition or a half-court offense, Christopher is always a threat to soar to the hoop and create space for himself and his teammates. His defence may not be NBA-ready just yet, but his quickness and athleticism should in time make him a very good on-ball defender.

It's difficult to be a starting guard in today's pro game unless the 3-point shot is a big part of your arsenal and Christopher would need to work on that aspect of his game from the start. His mid-range shot is solid, but NBA defenders are far more difficult to overcome than those in college. He will also need to improve his shot selection and decision-making but that comes with experience and maturity.

AARON HENRY - Michigan State

Henry is arguably the best defender available in this class with his 6-foot 10 wingspan, instincts and versatility. His ability at that end of the court alone could make him a valuable piece, but he has the necessary skills to contribute on the offensive end as well.

Henry was named to the All-Big Ten third team after averaging 15.4 points, 5.6 rebounds, 3.6 assists, 1.3 steals and 1.3 blocks as a junior. He was the first Michigan State player to lead a team in points, rebounds and assists since assists were first recorded in 1975.

As the focal point, Henry basically dragged the Spartans into their 23rd straight NCAA Tournament with limited help from his team-mates this past season. Henry is excellent in the mid-range and his 3-point shot is better than he gets credit for. After shooting 9-for-43 (20 percent) from long range in the first 14 game of the 2020-21 season, Henry knocked down 39.5 percent (15-for-38) over the last 14 games.

While he is unlikely to wow anyone with his physical skills and is not yet a polished offensive player, Henry is more than capable of holding his own against NBA competition. His ball-handling, passing and shot creation are very good and his mid-range output compares favorably to current NBA players Khris Middleton and Jamal Murray when they were coming out of college.

A smart and unselfish player, Henry is an excellent value pick in the second round and projects as a rotation player in the NBA.

Red Bull have requested a review with the FIA over the 10-second penalty given to Lewis Hamilton following his collision with Max Verstappen at the British Grand Prix.

Hamilton made contact with title rival Verstappen on the first lap at Copse Corner in this month's race, which the Mercedes driver went on to win despite the penalty.

Verstappen was taken to hospital for checks after a 51G impact with the tyre barrier at Silverstone and Red Bull argued the punishment handed to Hamilton was not severe enough.

Red Bull boss Christian Horner accused the Briton of "dirty driving" at the time and suggested a challenge would be lodged.

Formula One's governing body the FIA confirmed on Tuesday the team had submitted a petition for a review of the incident, with Red Bull and Mercedes officials being summoned to attend a video conference on Thursday.

A review is permitted if "a significant and relevant new element is discovered which was unavailable to the parties seeking the review at the time of the decision concerned."

Speaking last week, Horner said Verstappen's crash with Hamilton cost Red Bull around $1.8million, an outlay that will have "massive ramifications" for the team.

Hamilton heads into next weekend's Hungarian Grand Prix eight points behind Verstappen after triumphing on home soil for a record-extending eighth time.

South Africa have handed Jasper Wiese his first Test start and made three changes to their team to face the British and Irish Lions.

The second Test takes place in Cape Town on Saturday after the Lions came from behind to win the opener 22-17.

Hosts South Africa have brought in Wiese at number eight, while there are two changes to the front row as prop Steven Kitshoff steps in to win his 50th cap alongside the returning Frans Malherbe.

Kitshoff comes in for the injured Ox Nche and Trevor Nyakane drops to the bench to make space for Malherbe.

Leicester Tigers star Wiese was not even on the bench for first Test but he will come straight into the XV to replace Kwagga Smith.

Wiese has only previously made one substitute appearance at senior international level, which came in a warm-up match against Georgia this month.

Flanker Siya Kolisi will again captain the Springboks, whose coach Jacques Nienaber knows the stakes could not be higher.

"This is a massive game for us; it is do or die in order to stay in the race to win the series," Nienaber said as he discussed his team.

"We selected a team that offers continuity in selection, but also that we thought would be the best suited to achieve the objectives we have set for this match.

"Ox did well in the scrums last week and has been ruled out due to injury, but fortunately we have a world-class player in Steven who can step into the starting team. 

"The fact that this will mark his 50th Test will make this occasion even more important for him.

"We disappointed ourselves last week, and we all know how important it is to bounce back with a strong performance and show our fighting spirit and pride as a team and nation."

Six of the eight Springboks replacements are forwards, with Herschel Jantjies and Damian Willemse the only backs on the bench.

Earlier on Tuesday, the Lions also announced three changes to their starting XV.

Warren Gatland picked Mako Vunipola, with Conor Murray and Chris Harris also coming into the team to face the world champions.

In the 13 series in British and Irish Lions history when the tourists have won the first Test, they have gone on to win 10, draw one and lose just twice.

It has happened in five such series against South Africa, leading to four wins and one draw.

Following their first Test win, the Lions are unbeaten in their last three Tests, their best run since a six-game spell spanning the 1971 and 1974 tours.

South Africa: Willie le Roux, Cheslin Kolbe, Lukhanyo Am, Damian de Allende, Makazole Mapimpi, Handre Pollard, Faf de Klerk; Steven Kitshoff, Bongi Mbonambi, Frans Malherbe, Eben Etzebeth, Franco Mostert, Siya Kolisi (captain), Pieter-Steph du Toit, Jasper Wiese.

Replacements: Malcolm Marx, Trevor Nyakane, Vincent Koch, Lood de Jager, Marco van Staden, Kwagga Smith, Herschel Jantjies, Damian Willemse.

Juventus head coach Massimiliano Allegri says he expects Cristiano Ronaldo to demonstrate even greater responsibility this season.

Allegri returned to the club for a second spell in May, having previously guided the Bianconeri to five successive Scudettos and two Champions League finals between 2014 and 2019.

The 53-year-old will be looking to help Juve regain the Serie A title after they surrendered their crown to Inter last season.

Question marks remain as to whether or not his attack will be led in the new campaign by Ronaldo, with speculation linking him with a move away from Turin.

The Portuguese talisman top-scored in Serie A last term with 29 goals, taking his tally with the club to 101 since arriving from Real Madrid in 2018.

Ronaldo, who returned to pre-season training on Monday following an extended break due to his Euro 2020 exertions, has one year remaining on his contract at the Allianz Stadium.

Nevertheless, the 36-year-old remains firmly in the plans of Allegri, though the head coach warned that his game time may be reduced to accommodate team rotation during another hectic campaign.

“Ronaldo is a great player and a smart guy,” he said. “I spoke to him yesterday, as I did with the others.

“I told him that this is an important season and that I am happy to meet him again.

“Now, he has more responsibility because three years ago, we had a more experienced team, while now there are younger players.

“I expect a lot from him as an experienced player. He is in good condition and he is fit.

“There are different moments in a season, playing one game every three days. I’ll need to rotate the team, involving all the players and it also applies to him.”

The United States will face the Netherlands in the quarter-finals of the women's football tournament at Tokyo 2020 after being held 0-0 by Australia to finish second in Group G.

USA bounced back from a shock 3-0 loss to Sweden in their opening game with a 6-1 win against New Zealand, but they dropped further points in the round-robin stage on Tuesday.

Previously unbeaten in 44 games before that Sweden loss, USA failed to break down Australia's defence – Alex Morgan's disallowed goal for offside the closest they came to doing so.

Mary Fowler hit the crossbar for Australia and in the end a point apiece was a fair outcome, with the Matildas also advancing to play Great Britain in the last eight.

It is the first time in history record four-time winners USWNT have finished with fewer than six points in the group stage of a major global tournament.

RAMPANT DUTCH AWAIT USA

Sweden were already assured of a place in the last eight ahead of their clash with New Zealand and saw the job through with a 2-0 win at Miyagi Stadium to finish ahead of USA.

Anna Anvegard and Madelen Janogy were on target for Sweden before half-time and they saw out a straightforward win that condemned New Zealand to a group-stage exit.

It means USA will now take on the Netherlands in the next round in what is a repeat of the 2019 Women's World Cup final. The Netherlands lost that match, but they enter this latest showdown in superb form after thrashing China 8-2 in Yokohama.

Lineth Beerensteyn, Lieke Martens and Vivianne Miedema all scored twice in the one-sided affair, while Shanice van de Sanden and Victoria Pelova were also on target.

The Netherlands' tally of 21 goals from three games is already the most scored by a team in a single women's football Olympics event, surpassing the USA's 16 from London 2012.

HOSTS JAPAN SCRAPE THROUGH

Japan did all that they could in the final round of group games by beating Chile 1-0 through a Mina Tanaka goal 13 minutes from time.

That win took the tournament hosts to four points from three games, enough to send them through as one of the best third-placed sides, along with Australia.

Already through to the quarter-finals, Great Britain snatched top spot with a late 1-1 draw against second-placed Canada in Tuesday's other Group E match.

Caroline Weir's long-range free-kick with 84 minutes played took a heavy deflection and cancelled out Adriana Leon's opener.

Brazil also booked their spot in the knockout stages thanks to Andressa's first-half free-kick in their 1-0 win against the tournament's lowest-ranked side in Zambia, who lost Lushomo Mweemba to an early red card. 

The Selecao meet Canada in the quarters, while Australia await Great Britain.
