I Watched Lance Armstrong Dope: Teammate

Another former teammate says he witnessed cycling champ Lance Armstrong use banned substances. Tyler Hamilton, who raced alongside Armstrong in the Tour de France for three seasons, told CBS' 60 Minutes that he saw his teammate inject himself with EPO, a drug that raises endurance by boosting the number of red blood cells in the body.

"I saw him inject it more than one time like we all did, like I did many, many times," says Hamilton, who retired from cycling in 2009 after failing a dope test. Armstrong firmly rejects the allegations. Hamilton "is a confessed liar in search of a book deal—and he managed to dupe 60 Minutes," a lawyer for Armstrong tells the Wall Street Journal. "Most people will see this for exactly what it is: More washed-up cyclists talking trash for cash." (More EPO stories.)
