The United States men's 4x100 relay team from the 2012 Summer Games in London was stripped of its silver medal in the wake of Tyson Gay's doping case.
The IOC released a statement confirming the decision:
Following the sanctions received by Tyson Gay from USA Track and Field (USATF), and based upon the rules of the International Association of Athletics Federations (IAAF), the USA men’s 4 x 100m relay team, composed of Kennith Ryan Bailey, Jeffery Demps, Justin Gatlin, Tyson Gay, David Petrell Kimmons and Darvis Patton, who won silver at the 2012 London Olympic Games, has been disqualified.
Stephen Wilson of the Associated Press first reported the news and noted that Gay had already returned his medal as part of his initial punishment for the violation.
The USOC issued a statement on the disqualification:
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.
Justin Gatlin, Trell Kimmons and Ryan Bailey participated in the final heat with Gay. Jeffery Demps and Darvis Patton were also on the squad.
The United States finished second to a star-studded Jamaican group that included Usain Bolt and Yohan Blake with a time of 37.04 seconds.
Trinidad and Tobago collected the bronze medal, and France finished in fourth place. Wilson's report notes that it's unclear at this time whether the medals will be exchanged, bumping up each of those other teams one spot and giving the French runners a podium result.
Jon Williams of the Associated Press highlighted that the disqualification could mean the French will be getting a medal they deserved:
The change will not have an impact on the medal table. The United States finished with both the most gold medals and the most overall medals in London by a considerable margin.
