Lindsey Vonn will miss the rest of the ski season after crashing during the super-G at the world championships Tuesday in Schladming, Austria, and being airlifted to a hospital.
Vonn tore her anterior cruciate ligament and medial collateral ligament in her right knee and has a lateral tibial plateau fracture, according to a statement by U.S. ski team medical director Kyle Wilkens on the team's website.
The injury ends Vonn's quest this year for a fifth overall World Cup title.
She is expected to return for the 2013-14 World Cup season as well as the 2014 Winter Olympics in Sochi, which begin a year from this week. Vonn won a gold in downhill and bronze in super-G during the 2010 Games in Vancouver.
The injury occurred while Vonn was landing a jump. After losing balance on her right leg, with her knee bending awkwardly, her ski came off immediately, causing her to go off course and hit a gate before stopping.
