American track star LaShawn Merritt tested positive for a banned substance used in an over- the-counter male enhancement product, an embarrassing episode for an Olympic gold medalist who provided one of the best feel-good stories in Beijing.
Merritt, who overcame his rival Jeremy Wariner to win the 400-meter gold at the Olympics, accepted a provisional suspension Thursday, agreeing to sit out while the U.S. Anti-Doping Agency resolves his case.
Merritt, 23, said he hopes his family, friends and sponsors will forgive him for making “a foolish, immature and egotistical mistake.”
According to a release from Merritt’s lawyer, Howard Jacobs, the sprinter used a male enhancement product containing substances that caused him to fail three successive tests between October 2009 and January 2010.
If that’s the extent of his positive tests, it would presumably not put his Olympic medals or his 2009 world championships at stake. Merritt won gold in the 400 at the 2009 worlds in Berlin and teamed with Wariner to win the 1,600-meter relay in Beijing and Berlin.
