Former world 100m record holder Asafa Powell confirmed on Sunday that he had failed a drugs test.
Jamaican star Powell was the second leading sprinter on Sunday to fail a dope test following America’s former world champion Tyson Gay.
“I will confirm that a sample I gave at the National Trials in June has returned ‘adverse findings’,” said the 30-year-old Powell in a statement released on his Twitter account.
“The substance oxilofrine was found, which is considered by the authorities to be a banned stimulant.
“I want to be clear…that I have never knowingly or wilfully taken any supplements or substances that break any rules.
“I am not now nor have I ever been a cheat.”
