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.
