He won Olympic bronze in Rio five years ago and had been expected to contend for another medal in Tokyo.

Steve Bunce
Commentator on BBC Radio 5 Live
A straightforward fight but [Frazer Clarke] has given himself away there. He looks exhausted - and he shouldn't be. He's only done nine minutes!
Part of that has to be relief. From 2010 to 2021, it's a long time for a dream to get closer.
He's had taste of Olympic glory today and there's plenty more to cone.
Great Britain 0-1 Netherlands
Image source, Getty ImagesBritain are battling well as they try to get back on terms against the third-ranked Dutch, but can't find a leveller before the half-time break.
Adam Dixon and Zach Wallace both have shots saved by the Dutch keeper.
Remember: all is not lost for Britain if they lose this penultimate group match.
A win or draw would guarantee GB’s place in the quarter-finals with a game to spare. If Canada and South Africa both fail to win, GB would go through even with a defeat.
Women's 4x200m freestyle

Another 10 metres and Katie Ledecky would have had it. Katie probably had a little bit too much to do in the end but she was so close to touching her out! China just held on.
Women's 4x200m freestyle
What a race. China take the gold in a new world record.
Junxuan Yang, Muhan Tang, Yufei Zhang and Bingjie Li, take a bow girls.
The USA, anchored by Katie Ledecky and Australia, who were thought to be unbeatable over this distance, also broke the previous world record.
That was stunning.
Men's super-heavyweight (91kg+)
Image source, Getty ImagesGood workout for Frazer Clarke, who gets under way with a comfortable victory.
The British super-heavyweight went through his full repertoire of shots against Ukraine's Tsotne Rogava. He wins a split decision (4/1).
Never in doubt really.
Great Britain 0-1 Netherlands
Bad news for Great Britain. The Netherlands have just scored a superb goal - a demonstration of skill, vision awareness and movement - to carve open the British team.
A flick over the top of the British defence was delicately taken down before an intricate move was finished off at close range by Thierry Brinkman.
That came a few minutes after GB were unable to convert any of two penalty corners.
Men's 200m individual medley
Image source, Getty ImagesAnother swim and another win for Duncan Scott. He reaches the 200m individual medley as the second quickest over the semi-finals.
The 24-year-old broke the British record at the Olympic trials in April and is the current world number two in an event he probably doesn't even regard as his strongest.
He looked in fine fettle there.
Great Britain 0-0 Netherlands
Image source, Getty ImagesThe hooter goes on the first of the 15-minute quarters in the men's hockey match between Great Britain and the Netherlands.
No goals but suspect the British lads won't be too unhappy with that.
Britain are looking to get back to winning ways against a Dutch side ranked third in the world after a sobering 5-1 defeat by Germany on Tuesday.
A win or draw would guarantee GB’s place in the quarter-finals with a game to spare. If Canada and South Africa both fail to win, GB would go through even with a defeat.
With intense heat and humidity at the Oi Hockey Stadium, it is time for plenty of water down the neck and ice towels on the head.
Men's super-heavyweight (91kg+)
Head over to BBC Radio 5 Live or the BBC Sounds app to listen to Frazer Clarke take on Ukrainian Tsotne Rogava.

Men's 100m freestyle
Anyone remember when Michael Phelps raced a Great White shark, well sort of, it was a computer animated version.
Caeleb Dressel's first 50m was a bit like that!

Image source, Getty ImagesWhat a morning's knock by Austria's Sepp Straka.
The world number 161 leads the men's golf after sinking eight birdies - and not dropping a shot - in his opening round of 63 at the Kasumigaseki Country Club.
Straka, 28, has a two-shot lead over Belgium's Thomas Pieters, who is also back in the clubhouse, and Mexico's Carlos Ortiz.
Great Britain's Paul Casey is three under after 13 holes, although home favourite Hideki Matsuyama - the Masters champion, of course - has dropped back to two under.
Fellow Brit Tommy Fleetwood has just birdied the sixth to go one under, where he is alongside Irish pair Rory McIlroy and Shane Lowry.
Men's hockey

GB will probably still be smarting from the 5-1 thrashing they received from Germany a couple of days back.
Women's 100m freestyle
Image source, Getty ImagesAnna Hopkin, who is through to the final of the women's 100m freestyle, speaking to BBC Sport: "That was not a good finish.
"When I saw the time I thought I was out, so I was really happy to see that I was in eight. I knew it was going to be tough coming back this morning and trying to go faster, but I've got a day now to reset and come back tomorrow.
"It's just that transition from heats to semi-finals: trying to get to sleep, get a good night, come back the next morning and try and go faster. I'm just going to reset, have a look at the video and sort out that finish for tomorrow."

Women's double sculls
Image source, Getty ImagesImogen Grant, who finished fourth along with Emily Grant in the women's double sculls, speaking to BBC Sport: "In a lot of ways pretty much everything went to plan.
"We knew it was going to be exceptionally tight. We knew the other crews have exceptionally high standards. We knew we were going to execute our race plan as best as we possibly could and find another gear if we could.
"And to be honest, all those things went to plan. It just wasn't the outcome we had hoped for. As with an Olympic final, my legs felt like they were going through treacle in the last few strokes - and that's where we probably might have lost it. But ultimately that means we emptied the tank completely."
On missing out on an Olympic medal: "I'm sure it'll will sink in. At the moment, I'm just trying not to puke too much! Trying to make sure I don't pass out - all the really visceral feelings.
"Being at an Olympic Games is about more than just a medal. It's about where you have come over the last two years from out medal in 2019. Obviously we were hoping to come away with a medal here, but ultimately I'm really proud of what we have done."
Men’s super-heavyweight
Image source, Getty ImagesThe longest-serving member of the GB boxing squad finally gets his Olympic chance.
Frazer Clarke had to watch on as Anthony Joshua won gold in 2012 and Joe Joyce silver in 2016, but says he has learned from his time sparring with them. “I’m like a sponge, drinking it all in. There’s no shame in that, there’s things I can copy like how he lives the life."
The 2018 Commonwealth champion faces Ukraine’s Tsotne Rogava (04:36 BST), who is a multiple world champion in the kickboxing discipline of Muay Thai.

Image source, PA MediaYou can see at the end the relief for Caeleb Dressel. He knew it was going to be tight.
The press back home and the swimming world are going 'you're the new Michael Phelps'. There is expectation from the American press.
When we covered the international swimming league, he's all about the team and his team-mates, he plays his part.
He is the new Michael Phelps to me. But he has to back it up - which he does.
