What is the latest news?
Usain Bolt will run in the 4x100 metres relay heats for Jamaica on Saturday despite being a bit sore after winning bronze in the 100m final at the weekend, he told Reuters on Monday.
"We'll see, we haven't done any baton changes as yet with the guys, but I feel we are ready," said the 11-time World Championships gold medallist.

"I have talked to Julian Forte (100m semi-finalist) a little bit. I haven't really talked to the youngsters so we'll see when it comes to the baton changes, but I'm always excited to run relays and we see what the guys are prepared and ready to do."
Yohan Blake is the only other experienced member of Jamaica's sprint relay pool to have won medals at the World Championships or Olympics.
"Physically I am alright, there is a little bit of pain, but nothing a massage can't cure, I'm taking it easy," Bolt said of his condition two days after clocking a season's best equalling 9.95 seconds in the 100m final.
What are they saying?
Usain Bolt on Justin Gatlin's victory:
"I'm just showing respect. We've been battling for years and he finally got one (gold); yes it's at the end of my career but I have to show respect and where respect is due," added the Jamaican, who insisted his legacy remains intact.
"If you work hard throughout your life, I always say anything is possible and I can imagine how long he (Gatlin) has dreamt of this moment...
"I can't be a sore loser; throughout my career I've dominated. I personally don't think it (the bronze medal) has changed what I have done in any way."
What's our prediction?
Jamaica won gold in Rio last summer and it's difficult not to back Bolt to bow out on a high in London this time around.
