News Lance Armstrong will not contest drug charges by the U.S. Anti-Doping Agency is another chapter in the tainted history of cycling's Tour de France winners.
USADA plan to strip Armstrong of the seven successive Tours he won between 1999 and 2005, while the American has refused to "participate in a process that is so one-sided and unfair".
Armstrong maintains he is innocent but his unwillingness to fight USADA - in the same week in which a Texas court dismissed his lawsuit against the body - means he is the fourth winner of the famed Gallic race to be tarnished.
Here are the others...
- Bjarne Riis admitted doping during the 1996 Tour de France and organisers have since stated they no longer consider him to be the winner.
Ironically Schleck's brother, Frank, was withdrawn from the 2012 Tour after he tested positive for the banned substance Xipamide, which is used for the treatment of oedema and hypertension.
On the official Tour de France website, both Riis and Contador are still listed as winners.
