DENVER (AP) — Antonio Pettigrew gave up his Olympic gold medal Tuesday, two weeks after the sprinter admitted in court that he cheated to win at Sydney in 2000.

During last month's trial involving former track coach Trevor Graham, Pettigrew came clean about using banned substances EPO and human growth hormone from 1997 to 2003. Graham, his one-time coach, was found guilty of lying to federal investigators about his relationship to a steroids dealer.

Pettigrew's decision to give up the gold for the 1,600-meter relay was expected, and it came only a day after one of his teammates, Michael Johnson, also said he was giving back his relay medal in response to what Pettigrew had admitted.
