BERA, Spain (AP) -- American cyclist Levi Leipheimer will be sidelined indefinitely after breaking his left leg when he was hit by a car in training.

His Omega Pharma-Quickstep team says X-rays diagnosed a broken leg after he was hit on Sunday while riding solo ahead of the Tour of Basque Country.

Leipheimer was "disappointed" but relieved to have broken the smaller bone in the lower leg as "I can't communicate how close I came to being killed and that was incredibly scary."

Leipheimer will be sidelined for two weeks before the team evaluates the full length of his recovery. The former teammate of Lance Armstrong and Alberto Contador hopes to return in May for the Tour of California.
