Reigning Giro d'Italia champion Ryder Hesjedal of Canada is focusing on the London Olympics after a left leg and hip injury forced him out of this year's Tour de France.

Hesjedal, who was injured during the crash-marred stage 6 of the Tour de France, did not join his Garmin-Sharp teammates at the start of Stage 7 and is scheduled to fly home later Saturday. His Garmin-Sharp team said Hesjedal was not able to pedal because of the leg injuries.

Hesjedal was among at least two dozen riders caught up in a nasty crash with 16 miles to go on Friday. He lost more than 13 minutes and dropped to 108th overall.

"The problem is that the swelling is to a degree that he can't actually bend his leg, and you obviously need to bend your leg to race a bike," Team Garmin-Sharp manager Jonathan Vaughters explained.

In a statement released by his team, Hesjedal said he was disappointed to abandon the race, ruing the fact that he was looking forward to reaching the mountains.

"I only took a few days off the bike after the Giro before I started training again, and I have been very focused on doing a great Tour," Hesjedal commented and added "It's a huge disappointment."

Hesjedal will try to recover quickly in order to be ready for the London Games, where he is expected to compete with the Canadian team.

"I'll go home, keep working with the medical staff on my recovery, and re-focus everything on the Olympics," he said.

Another Garmin-Sharp rider, Robbie Hunter of South Africa, had to pull out ahead of Saturday's stage between Tomblaine and La Planche Des Belles Filles, in another blow to the American team.

Almost all of the Garmin-Sharp riders were caught up in Friday's pileup, the worst of this year's Tour so far. Vaughters hopes his riders will be able to reach the first rest day next week without more trouble and recover from their injuries.

"Then I think we'll have to play sort of an open and aggressive game and see how it goes," he said. "First things first. First thing is just to get to the rest day in a survival mode."

Garmin has had its fair share of trouble since the Tour started. The team lost Tom Danielson on Friday night while sprinter Tyler Farrar, who has crashed several times, is still looking for his first stage win.
