US sprinter Tyson Gay and Jamaica's former 100m world record holder Asafa Powell have failed drug tests.
Gay, 30, the joint-second fastest man over 100m, was notified by the US Anti-Doping Agency on Friday that his A sample from an out-of-competition test in May had returned a positive.
The management company for Powell confirmed he had tested positive for a banned substance.
