Olympic hurdler Duane Ross has received a two-year suspension from the US Anti-Doping Agency for using performance enhancing drugs.
The USADA announced the ban on Friday, along with the disqualification of all Ross' results in competition since November 2, 2001.
Ross was the runner-up in 110 meter hurdles at the 2004 Olympic Trials. He competed at the Athens Games.
Ross was one of several athletes to testify in federal court in 2008 against athletics coach Trevor Graham, who was convicted of lying to investigators in the BALCO steroid case. USADA says the sanctions against Ross resulted from recently received information from the BALCO.
