Track and field

* Sprinter Tyson Gay accepted a 1-year suspension yesterday after testing positive for a banned substance nearly a year ago, and returned the silver medal he won in the men's 400-meter relay at the 2012 London Olympics.

USADA announced that Gay's 1-year ban began June 23, the day his sample was collected at the U.S. championships.

As part of the penalty, Gay, the American recordholder in the 100, also accepted loss of results dating to July 15, 2012, the date when he first used a product that contained a banned substance. He was a member of the relay team at the London Games that finished second to a Jamaican team led by Usain Bolt. The Americans set a national record with a time of 37.04 seconds. He has given his medal back to the U.S. Olympic Committee.

USADA said in a statement that, upon receiving notification of his positive tests, Gay, 31, voluntarily withdrew from all competition prior to the 2013 world championships and has not competed since.

He could've been given a penalty twice as long, but received consideration after assisting USADA in the investigation into his positive test. USADA said he tested positive for the presence of an exogenous androgenic anabolic steroid.
