Britain's Andy Robertson, who injured himself in the men's 60m heats earlier today: "I felt my groin go out of the blocks. Everything felt fine in warm-up. I felt just as good as I did two weeks ago, so my confidence was really high.
"I thought I could carry on but I just couldn't. When I get back I'll see the doctor and hopefully it's nothing too serious."
While we've all been tucked up in bed this morning, action was already under way in China.
Great Britain's Jeremiah Azu cruised through to the semi-final of the men's 60m with the third fastest qualifying time of 6.53 seconds.
He goes in semi-final one at around 12:00 GMT and will hope to progress to the final, which is the last event at around 13:25.

She will race in the women's 1500m at the event in Nanjing from 21-23 March along with team-mate Revee Walcott-Nolan, who took bronze at the European Athletics Indoor Championships in the Netherlands last weekend.Read more and get the full GB squad here.
