Gay, the second fastest man over 100m, said he was notified by the US Anti-Doping Agency (USADA) on Friday that his A sample from an out-of-competition test in May had returned a positive.

His B sample is yet to be tested.

“I don’t have a sabotage story… I basically put my trust in someone and was let down,” said Gay, 30.

“I made a mistake. I am pulling out of Monaco (this week’s Diamond League meeting) and the World Championships.”

Gay ran the fastest 100m time of 2013 to win the US World Championships trials in June.
