The cyclist Tyler Hamilton, one of Lance Armstrong’s former teammates on the United States Postal Service team, said he saw Armstrong inject himself with the banned performance-enhancing drug EPO to win the Tour de France, according to a report on CBS’s “60 Minutes” that will run Sunday.

“I saw him inject it more than one time,” Hamilton said in an interview broadcast Thursday on the CBS Evening News. “Yeah, like we all did. Like I did many, many times.”

Hamilton, the 2004 Olympic champion in the time trial, who has been sanctioned for doping twice, is the latest Armstrong teammate to say he saw Armstrong use performance-enhancing drugs, including testosterone, and blood transfusions. A year ago, Floyd Landis, who was stripped of the 2006 Tour de France title for doping, shook the world of cycling by saying he and Armstrong were part of a systematic doping scheme while racing for the Postal Service team.

Since then, Armstrong — the seven-time Tour winner, who vehemently denies ever doping and has never been sanctioned for doping — has become a target of a federal investigation of drug use in cycling. Hamilton and other former teammates testified to the grand jury in the case.
