The whole field has taken three of their six throws in the men's shot put.

Olympic champion Ryan Crouser continues to dominate, his opening throw of 22.36m is still the benchmark.

Britain's Scott Lincoln is currently 10th.

Dutch 400m athlete Lieke Klavier, speaking to BBC Sport.

On her yellow card: "I knew it, I felt my right leg shake and I thought they were going to give me a yellow card.

"I had one plan so that didn't change because of the yellow card - I am so excited and I cannot wait for tomorrow."

On her plan tomorrow: "I am not sure, I think it will be faster maybe slower [her first lap], but I am not sure what the plan will be tomorrow."

Bol is such a beautiful runner, that time of 50.66secs is so relaxed and controlled.

She puts herself in such a good position and when you are so good at your event it is a true blessing - Bol ran it so technically well.

Laviai Nielsen reached the final by just 0.04 seconds. That was the gap between her and fourth place Henriete Jaeger.

It doesn't matter if you do it by 0.04 seconds or four minutes, however. The Brit is in the final.

Morgan Lake didn't give herself the opportunity when she was so close to the bar and it's very unlucky - she has made hard work of this high jump competition.

By the narrowest margin!

Nielsen just catches Henriette Jaeger on the line to snatch third place and a spot in the final.

Femke Bol dominated that semi, coming home in first place.

Femke Bol has hit the front at halfway. Laviai Nielsen has work to do.

Here we go, the second semi in the women's 400m, starring Femke Bol and British champion Laviai Nielsen.

Can Morgan Lake make it third time lucky for the third time in this women's high jump final?

The rhythmic clapping begins. A British flag waves in front of her...

Ah, but it's not there for Lake, who bows out with a best height of 1.92m.

She stands with her hands on her hips and looks back at the bar. What might have been.

No, Morgan Lake suffers her third straight failure - one at 1.95m, then two at 1.97m - which means she is out of the final.

No medal for Britain in this event.

Nicola Olyslagers is the second woman over at 1.97m.

Can Morgan Lake join them?

Definitely worth keeping an eye on the second semi of the women's 400m.

Femke Bol continues her pursuit of a first world indoor title and has even been backed to break her own world record of 49.24 this weekend by her coach Laurent Meuwly, who said: “She is better than last year, I really think she has saved something for Glasgow.”

British champion Laviai Nielsen is also in the mix for a final place.

Lieke Klaver of the Netherlands wins the semi, with Talitha Diggs of the USA second.

Third, and also through the final, is the Irish runner Sharlene Mawdsley. The sizable group of Irish fans in the stadium liked that!

We get away fine this time.

Lieke Klaver leads the field after her reprieve.

Lieke Klaver gets a yellow card for "disturbance of the race", but she is allowed to stay in the field.

Let's try that again.

False start!

It looks as if Lieke Klaver of the Netherlands may have gone too early.

Heart in mouth time...

Here we go, time for the 400m semis, starting with the women.

Six in each semi, the top three reach tomorrow's final.

So far, only Ukraine’s Yaroslava Mahuchikh has made it over 1.97m, of the six athletes remaining.

The other five women all failed their first attempts.

Morgan Lake has decided to pass at 1.95m and carry her second attempt to the new height of 1.97m.

That's the height she jumped to finish fourth in Budapest. Can she replicate that here in Glasgow and put herself in the medal mix?

You can bet the crowd will do their very best to ensure she does.

So, that was chaotic.

We were supposed to only have 12 finalists in the men's 1500m, but we will have 14 after Adam Fogg of Britain and Ethiopia's Biniam Mehary were both awarded places after being tripped in their heats.

14 men on track! It could be mayhem.
