Former world champion Cadel Evans withdraws from Olympic time trial

LONDON - Former world champion Cadel Evans of Australia has withdrawn from the Olympic time trial.

The Australian Olympic committee said Evans, who finished 79th in the road race, is too tired to compete in Wednesday's race against the clock.

Evans' teammate Michael Rogers will be the only Australian athlete to compete in the men's time trial.

Evans struggled with his physical condition earlier this month, failing to defend his Tour de France title.
