Seven-times Tour de France winner Lance Armstrong crashed out of the Tour of California on Thursday shortly after he dismissed a former team mate's claim that he used performance-enhancing drugs.
Armstrong withdrew from the event after a crash left the American bloodied and sent to hospital for precautionary X-rays during a fifth stage that saw Australian Michael Rogers grab the overall lead.
Rogers became the fourth new leader in five days with his second-place finish to Slovakia's Peter Sagan in the 195.5-km stage from Visalia to Bakersfield.
Prior to the stage, Armstrong denied accusations by Floyd Landis that he used performance-enhancing drugs.
Landis, stripped of his 2006 Tour de France victory after failing a doping test, ended years of denial on Wednesday when he confessed to using drugs from 2002 when he joined the US Postal team and was a team mate of Armstrong.
Armstrong crashed with several other riders in the opening kilometres of Thursday's fifth stage.
He Needed eight stitches below his left eye and X-rays on his elbow were negative.
‘It was a shame to have to abandon early and not be able to help Levi (Leipheimer) to another victory,’ said Armstrong, who kept riding but later quit because of the injuries.
Rogers, a three-time World Time Trial champion, began the day trailing American Dave Zabriskie for the overall lead, but with the help of a time bonus he won a tiebreaker for outright lead because of better accumulative stage finishes.
‘Obviously, I woke up this morning and heard the news like everyone else did,’ said Rogers of Landis's revelations. ‘I came here to win this race and that's what I concentrated on. During the race I didn't think of anything else but.’
American Levi Leipheimer, winner of the last a three Tour of California races, is third while Sagan is fourth overall.
