SCHLADMING, Austria, Feb 5 (Reuters) - Olympic champion Lindsey Vonn will miss the rest of the Alpine skiing season after fracturing her shin and tearing knee ligaments in a crash during the opening super-G at the world championships on Tuesday.
"According to U.S. Ski Team medical director Kyle Wilkens, Vonn suffered a torn ACL and MCL in her right knee and a lateral tibial plateau fracture," the U.S. team said in a statement.
"She will be out for the remainder of this season but is expected to return to racing for the 2013-14 Audi FIS World Cup season and the 2014 Olympic Winter Games in Sochi," the statement added.
The American four-times overall World Cup champion tumbled down the piste after a jump halfway down the race, which started three-and-a-half hours behind schedule in poor visibility.
Vonn, who nearly somersaulted across the snow, was heard screaming in pain on the side of the course. She was flown to hospital in Salzburg by helicopter.
Slovenia's Tina Maze won the race ahead of Swiss Lara Gut and Vonn's compatriot Julia Mancuso. (Editing by Clare Fallon)
