The “second fastest man in history” has tested positive for a banned substance and has pulled from the world championship that is scheduled for next month in Moscow.

In 2007, Gay won the 100 meters, 200 meters, and 4×100 meter race, making him only the second man in history to win all three. Just last month, Gay won the 100 meters and 200 meters and had fans anticipating his performance at the world championship.

Gay was notified by the U.S. Doping Agency last week that he had tested positive for a banned substance after completing an “out-of-competition” drug test on May 16th. Gay is scheduled to have his “B” sample, which is “a urine or blood sample used in doping tests in professional sports to confirm or invalidate the presence of banned substances in the first sample, the A-sample”, soon and could be as early as this week.

absolutely devastated by the news about Tyson Gay. Desperately hoping his B-sample comes back clean; knowing it won't.

Gay did not deny the accusations and is taking full responsibility for his actions.

“I’m going to be honest with USADA, about everything, everybody I’ve been with, every supplement I’ve ever taken, every company I’ve ever dealt with, everything”, said Gay. “They already know it is some type of accident, or some type of — I don’t want to use certain words, to make it seem like an accident, because I know exactly what went on, but I can’t discuss it right now,” he said. “My career and my name have always been better than medals or records or anything like that. I’ve always wanted a clean name with anything. Unfortunately, I have to break this news, that I have a positive ‘A’ sample.” Gay says that he is letting the USADA handle the situation and will take whatever punishment that they decide to give him.
