Former Olympic sprinter Tyson Gay's failed drug tests were for a banned steroid, meaning he faces a two-year suspension from the sport, reports BBC Sports' David Bond.
Gay, the U.S. record holder in the 100 meters, admitted to a positive test last month. He reportedly failed an out-of-competition test in May and a test at the U.S. World Championship Trials in June.
"I don't have a sabotage story," Gay said at the time. "I don't have any lies. I don't have anything to say to make this seem like it was a mistake or it was on USADA's hands, someone playing games. I don't have any of those stories. I basically put my trust in someone and I was let down."
The BBC obtained parts of a letter sent to Gay by the US Anti-Doping Agency about the failed test at the trials. Because officials reference a carbon isotope test, the BBC reports the positive test was likely for testosterone or one of its precursors, such as DHEA or androstenedione.

Gay pulled out of the World Championships. There is speculation that he is cooperating with officials in hopes of reducing his suspension.
