Tyson Gay returns medal after dope ban

Colorado Springs: US sprint star Tyson Gay has received a one-year doping ban from the US Anti-Doping Association and returned his 2012 London Olympics silver medal to the US Olympic Committee.

Usada announced on Friday that the 31-year-old American track star 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 by both USADA and the world governing body IAAF.

Gay accepted a one-year period of ineligibility that began on June 23 of last year, the day his sample was collected at the US Outdoor Track and Field Championships.
