"As expected, following USADA's decision in the Tyson Gay case, the IOC today confirmed that the U.S. team has been disqualified from the 4x100-meter race that was part of the athletics competition at the London 2012 Olympic Games. We will begin efforts to have the medals returned, and support all measures to protect clean athletes."
