The entire U.S. men's sprint relay team was stripped of its silver medal from the 2012 London Olympics on Wednesday as a result of Tyson Gay's doping case, two officials with knowledge of the decision told The Associated Press.

The officials spoke on condition of anonymity because the decision has not yet been announced.

The International Olympic Committee notified the U.S. Olympic Committee by letter that the 4x100 relay team has been disqualified and all the medals withdrawn, the officials said. The letter asks the USOC to collect the medals and return them to the IOC.

Gay returned his own medal last year after accepting a one-year doping suspension and the loss of results going back to July 2012, but the status of the U.S. second-place finish in London and the medals of Gay's relay teammates had remained in limbo until now.

Under international rules, an entire team can be disqualified and stripped of medals because of doping by one member.

Gay was a member of the American team that finished second in London behind a Jamaican team anchored by Usain Bolt. The Americans set a national record in the final with a time of 37.04 seconds.

The other U.S. team members losing medals are Trell Kimmons, Justin Gatlin, Ryan Bailey, Jeffery Demps and Darvis Patton. Kimmons, Gatlin and Bailey ran in the final with Gay.

Gay tested positive for steroids at the U.S. championships in 2013. He received a reduced suspension -- rather than a two-year ban -- because he cooperated with the U.S. Anti-Doping Agency's investigation that led to an eight-year ban for his former coach, Jon Drummond.

Gay's results were annulled going back to July 15, 2012, the date when he first used a product containing a banned substance.

If the London medals are reallocated, the silver will go to Trinidad and Tobago, which finished third in 38.12 seconds. The bronze would go to the French team which placed fourth in 38.16 seconds.
