Lance Armstrong has been stripped of his seven Tour de France titles and given a lifetime ban by the United States Anti-Doping Agency.
The US cyclist opted not to contest USADA drugs charges, saying he is tired of fighting the allegations. He strongly denies doping.
The International Cycling Union, the world governing body, is yet to say if it intends to follow USADA's lead.
It previously backed Armstrong's bid to challenge USADA powers over the sport.
USADA said Armstrong's decision not to fight the charges against him triggered the lifetime ban and led to his results dating back to 1st August 1998 being erased.
He won the Tour de France in 1999, 2000, 2001, 2002, 2003, 2004 and 2005.
