Lance Armstrong has returned his Olympic bronze cycling medal, the latest fallout from his confession to using performance-enhancing drugs.

Armstrong won the medal at the 2000 Sydney Olympics. The International Olympic Committee in January vacated the medal Armstrong won in the road time trial. Armstrong tweeted on Thursday that he gave it back and a US Olympic Committee spokesman released a statement confirming its return.

Armstrong's tweet included a photo of the medal and its blue ribbon along with the message: "The 2000 Bronze is back in possession of (at)usolympics and will be in Switzerland asap".'

Armstrong declined further comment.

The IOC has said it will not reallocate Armstrong's bronze medal, just as cycling's ruling body decided not to declare any winners for the Tour de France titles once held by the American. Spanish rider Abraham Olano Manzano, who finished fourth in Sydney, will not be upgraded and the bronze medal will be left vacant in Olympic records.

Armstrong denied doping for years until his confession in January in a TV interview. The confession came after a US Anti-Doping Agency report detailed widespread use of performance-enhancing drugs by Armstrong and his US Postal Service team. Armstrong also has been stripped of the seven Tour titles he won from 1999-2005.

The IOC previously stripped Tyler Hamilton, a former Armstrong teammate, of his time trial gold medal from the 2004 Athens Olympics after he acknowledged doping.

Armstrong won his medal two months after winning his second Tour de France title. His USPS teammate, Vyacheslav Ekimov of Russia, won the gold and Jan Ullrich of Germany won silver.
