SCHLADMING, Austria -- The U.S. Ski Team says Lindsey Vonn has torn the ACL and MCL in her right knee and also has a broken bone after a horrific crash Tuesday at the world championships.

The team says Vonn will undergo surgery and will miss the rest of this season but is expected to return in time for the 2014 Sochi Olympics.

The team says Vonn has "a torn ACL and MCL in her right knee and a lateral tibial plateau fracture."

Vonn lost balance on her right leg while landing a jump, flipped over in the air and landed on her backside as she smashed through a gate before coming to a halt.

The four-time overall World Cup winner and 2010 Olympic downhill champion received medical treatment on the slope for 12 minutes before being taken by helicopter to a hospital in Schladming.
