LONDON: American hurdler Duane Ross has been disqualified retroactively from the 2004 Athens Olympics for doping.
The IOC stripped Ross of his Athens results following the U.S. Anti-Doping Agency's decision to suspend him for two years for using banned drugs.
Ross finished fifth in his semifinal heat of the 100-meter hurdles in Athens and did not qualify for the final.
The International Olympic Committee says it was notified by USADA that Ross had been disqualified of all his results since Nov. 2, 2001, for doping.
Ross was one of several athletes to testify in U.S. federal court in 2008 against track coach Trevor Graham, who was convicted of lying to investigators in the BALCO steroid case.
