Cycling champion Lance Armstrong has confirmed he is facing new doping allegations that could strip him of his seven Tour de France titles.
The US Anti-Doping Agency (USADA) has brought formal doping charges against Armstrong, whose comeback from life-threatening cancer made him one of the most well-known sportsmen in the world.
In a
15-page letter addressed to Armstrong and others including his former team director Johan Bruyneel and sports doctor Michele Ferrari, USADA claims it collected blood samples from Armstrong in 2009 and 2010 that indicated the use of doping.
"With respect to Lance Armstrong, numerous riders, team personnel and others will testify based on personal knowledge acquired either through observing Armstrong dope or through Armstrong's admissions of doping to them that Lance Armstrong used EPO, blood transfusions, testosterone and cortisone during the period from before 1998 through 2005, and that he had previously used EPO, testosterone, and hGH through 1996," the letter reads.
