Peter Fredericsson (Sweden) 38.02

Malin Baryard-Johnsson (Sweden) 40.76

Daisuke Fukishama (Japan) 43.76

The Netherlands' Emma Oosterwegel wins the second 200m heat in the heptathlon, clocking a PB of 24.25 seconds.

Nafi Thiam places fifth.

Six riders. Three medals. Nervous times...

GB's Ben Maher, on Explosion W, is fourth up.

She didn't want to speak which is certainly understandable, but she wanted to finish (that race).

I think we all thought it was amazing to see her run such an amazing in the hurdles but there was a limping situation after the high jump and there was always going to be a lot of stress on the Achilles.

At the end of the first round of the hammer, Nick Miller is in fifth position.

Poland's Wojciech Nowicki leads with a massive throw of 81.18m.

Dame Jessica Ennis-Hill
London 2012 Olympic heptathlon champion on BBC TV

She had the best year of her life in 2019 and coming into an Olympic year she was in the best form she could be.

2020 ended up in injury, and for the years that she's had in the sport, she's had such blows.

And now Katarina Johnson-Thompson has been disqualified from the 200m for leaving her lane.

Athletics commentator on BBC TV

It's horrible because it was always a possibilty and we weren't going to know until she started competing.

She had to go for it, but I think we saw it first in the high jump and then this 200m, flat out, and it is so sad.

Andrew Cotter
Athletics commentator on BBC TV

It all comes crashing down as her Achilles has been her undoing.

She is composing herself and she desperately wants to finish here, but that is a sad, sad end.

Katarina Johnson-Thompson looks in some pain.

They bring a wheelchair on for her but she refuses, instead indicating that she wants to finish the race.

She hops her way to the finish line.

Belgium's Noor Vidts wins the heat in 23.70.

KJT flies out of the blocks but NOOOO.

She pulls up. Looks like it's that Achilles injury again.

KJT is in lane four in this first 200m heat.

Belgium's Noor Vidts, who currently holds bronze medal position, is also in this one.

Coming up shortly is the next event of the heptathlon - the 200m. Katarina Johnson-Thompson is in the first heat.

She currently sits fifth, after three of the seven events.

KJT is on 2,886 points, 139 points behind defending champion Nafi Thiam, who leads on 3,025.

Ben Maher makes it through alongside five other riders to fight for medals.

That jump-off will be at about 12:40 BST.

HERE WE GO...

Ben Maher up on Explosion W

Nick Miller is second to throw in this final.

It's a great opening effort from the Brit. He throws 77.88m.

Okay, are you sitting comfortably?...

First, it's Ireland's Darragh Kenny (Cartello) and then Great Britain's last man standing - Ben Maher, aboard Explosion W - bidding to make the jump-off.

Kenny does not make it.

How's the nerves?

The men's hammer final is about to get under way, featuring Team GB's Nick Miller.

Miller - the 2018 Commonwealth Games champion - is ranked 12th in the world and will be looking to better his 80.26m PB to be in with a shot of the medals.

Poland's Pawel Fajdek is the only hammer throw to win four consecutive world titles, with three of his four winning distances over 80m. He has already thrown over 81m five times this year, and his world leading throw of 82.98m is his fourth best of all-time.

Ireland's Bertram Allen, riding Pacino Amiro, is the latest to miss the jump-off after errors as the three Swedes lead the way.

There's four more to jump in this first round, with Ben Maher last up for Great Britain.
