INNSBRUCK, Austria (AP) -- World slalom champion Marlies Schild of Austria has had surgery on her right knee and won't defend her title on home soil in February.
The Austrian ski federation says Schild will be out three months after having a torn collateral ligament repaired at a hospital in Innsbruck on Friday.
Schild was hurt Thursday during training at the World Cup slalom in Are, Sweden.
The world championships are scheduled for Feb. 5-17 in Schladming. Schild also missed the world championships in 2009 in Val d'Isere, France, because of an injury, but came back to win the world title in 2011 in Garmisch-Partenkirchen, Germany.
A four-time World Cup slalom champion, Schild has won 33 races in the discipline, leaving her one short of matching Vreni Schneider's record.
