The United States Anti-Doping Association (USADA) banned star sprinter Tyson Gay for one year and urged him to return his 2012 Olympic silver medal to the US Olympic Committee.
The 31-year-old, who's a member of the US Olympic men's 4x100m relay runner-up squad at London, tested positive for a banned anabolic steroid in two random out-of-competition tests and one event doping test in urine samples taken last year, said USADA Friday, reports Xinhua.
Gay's one-year period of suspension began June 23 of last year, the day his sample was collected at the US Outdoor Track and Field Championships, meaning that he can return to competition next month.
