American rider Levi Leipheimer has been fired by the Omega Pharma-QuickStep cycling team after confessing to doping as part of the USADA investigation that brought down Lance Armstrong.

Showing character doesn't mean you are perfect.

Lance Armstrong's former manager Johan Bruyneel was forced to leave the RadioShack-Nissan team earlier today after being singled out as a central figure in the former Tour de France champion's doping program.

World Anti-Doping Agency director general David Howman said Lance Armstrong pursued what appears to be a systematic doping program for a decade "probably with the knowledge" of people who were charged with detecting drug cheats.

USA Cycling has announced it will enforce the sanctions issued by USADA and is currently reviewing the impact of the sanctions on historical results.

Former Lance Armstrong lieutenant George Hincapie admits to doping.

Lance Armstrong challenged the U.S. Anti-Doping Agency to name names and say what it had on him.

The head of cycling's governing body says the wait to receive the U.S. evidence in Lance Armstrong's doping case is a "cause for concern."
