Lance Armstrong has been stripped of his 2000 Olympic cycling time trial bronze medal, an International Olympic Committee (IOC) official told Reuters on Thursday.
American Armstrong was stripped of his seven Tour de France titles and banned for life by the International Cycling Union (UCI) in October after riders testified that he took drugs.
The testimony came in a United States Anti-Doping Agency (USADA) report in which the 41-year-old's former U.S. Postal team was accused of running "the most sophisticated, professionalized and successful doping program that sport has ever seen".
Armstrong has always denied wrongdoing but is due to appear on U.S. television later on Thursday and reports say he will confess.
The 2000 bronze was the only Olympic medal Armstrong ever claimed despite dominating cycling by winning the Tour from 1999 to 2005.
He retired for a second time in 2011.
