Andrew Pozzi will be furious, really annoyed with that. We know he is very fragile. It's taken him years for him to get where he is, but let's hope if it is an injury it's not too serious. I'm really happy he has at least managed to get a really quick time under his belt before getting on that plane to Rio.

Andrew Pozzi - who won his heat by a street - has been forced out of the 110m hurdles final.

Not quite clear what the problem is with the Briton. Better safe than sorry ahead of Rio I guess.

The show goes on though. The barriers are out of the final.

France's Dimitri Bascou is now the favourite. He has the prime lane five draw after winning the other heat.

Olympic champion Habiba Ghribi canters clear of the rest to win ahead of United States' Stephanie Garcia and Kenya's Purity Kirui.

Britain's Lennie Waite was unable to finish after a spill and spiking. Team-mate Rosie Clarke was 12th.

Greece's Katerina Stefandi leads the pole vault clear of world champion Yarisley Silva with Britain's Holly Bradshaw back in third with a best of 4.52m.

Croatia's Sandra Perkovic - European and Olympic champion - leads the discus with Britain's Lally Jade.

Take a look below at Katarina Johnson-Thomspon's winning leap of 6.64m. 

We are up and running in the women's steeplechase.

Kenya's Purity Kirui might be the pick. Britain's duo Lennie Waite and Rosie Clarke will be battling to stay in touch.

Jessica Ennis-Hill's coach Toni Minichiello: "I'm a little bit frustrated. Jess was leaning back a lot and slowing down into the final steps. There's a bit of a headwind out there but it's not an excuse, she just wasn't in an optimum position on the board.

"I haven't managed to speak with her but I'm happy I'm not travelling back to Sheffield with her today because she'll be frustrated  She's been training much better than that."

Katarina Johnson-Thompson, speaking to BBC Sport: "It's just the stadium, every time I come here I do a good job in the long jump. It's exactly what I wanted before Rio. 

"It gives me confidence I can get on the board there. Jess is such a strong competitor I know she'll do better than that at the Olympics. Gold will not be an easy job for anyone. I've got to step up to the competition."

Shara Proctor, who came second: "The knee is fine, I'm healthy and feeling free, everything is good. I can't focus on other competitors, I have to focus on myself. I just need to get better each week. I hit my goal which was to come here and get a season's best, so that's a real confidence boost for me."

That really was a very competitive race. In a strong headwind it's tough for the athletes but what an incredible performance from Marie-Josee Ta Lou. It will be a tough old final. Shelly-Ann Fraser-Pryce will have to be at the top of her game.

It's a season's best for Asher-Smith and the wind was against her but we expected a little bit more. It's a high-quality field but she might not have executed her race as well as planned.

There are things she can pick apart but that's a good run, and she can now give her all in the final.

Marie-Josee Ta Lou of the Ivory Coast gets out quickly, keeps driving and comes through in a time of 10.96. That is a 0.06 improvement on her personal best.

Dina Asher-Smith is third and through in a season's best 11.07 behind Michelle-Lee Ahye in 11.03.

Dina Asher-Smith, the 20-year-old British record holder - wins the decibel count as the names are read out for the second heat.

Trindad and Tobago's Michelle-Lee Ahye will be a threat to her in lane five.

Gemili came third in the 200m, won by Usain Bolt, on Friday and was part of the GB 4x100m relay team that impressed earlier today with victory in a world leading time.

Shelly-Ann Fraser-Pryce puts herself out in front of the field and just uses that stride to keep out there. It was important for Desiree to qualify. To return with the form she has done is fantastic. I'm hoping she can raise her game in the final.

Jamaica's diminutive speed queen Shelly-Ann Fraser-Pryce keeps the rest behind her with a win in 11.03 seconds.

Britain's Desiree Henry is into the final, coming third in 11.08 seconds.

A hugely impressive showing from Katarina Johnson-Thompson as she takes the sandpit spoils with a jump of 6.84m, just eight centimetres off her personal best.

Shara Proctor was second with 6.80m. Jessica Ennis-Hill has to settle for seventh with an underwhelming 6.19m.

Two heats.

First up is world and Olympic champion Shelly-Ann Fraser-Pryce.

Britons Desiree Henry and Louise Bloor will be trying to keep pace and secure on of three automatic qualifying spots.

We are expecting Mo to land on the track at 16:36 BST.

I'd love to see Kerron Clement keep that acceleration phase going longer. I think he's still a long way off from what he's capable of doing - he is world record holder for the 400m indoors remember. Let's hope that at Rio he can step up another gear and really prove he's world number one.
