Runner Debbie Dunn Out Of Olympics Due To Doping

After testing positive for the likely presence of an anabolic steroid, would-be Olympic runner Debbie Dunn will not be competing in the 4 x 400-meter relay at the 2012 Games in London. Dunn, 34, who is from Norfolk, Virginia and finished fourth in the 400 meters at the trials, dropped out of the U.S. Olympic team, issuing a statement saying she did not want to distract from her teammates' big day.

“I have been informed by the U.S. Anti-Doping Agencythat a sample I gave at the U.S. Olympic Trials contains an elevated testosterone/epitestosterone level," Dunn told The Chicago Tribune. "While I work with USADA to resolve this matter, I am withdrawing from my relay pool position for the 2012 Olympic Games. I do not want any issue like this to distract from my teammates’ focus for the biggest meet of their lives. I wish Team USA best in London as I work toward resolving this matter."

Dunn was the 2010 indoor world champion in the 400.
