American skier Lindsey Vonn successfully completes her mandatory downhill training run at the Winter Olympics just one week after rupturing her left anterior cruciate ligament.

A week after her ACL injury, Vonn clocked a successful practice session and is still on track to compete in Sunday’s medal race
