Vonn injured her right thumb Monday while opening a bottle of champagne at a victory celebration. She had surgery Tuesday in Austria to repair a tendon.
The U.S. Ski Team medical director said the surgery went fine and Vonn should be ready to compete in the slalom Saturday and perhaps Thursday's giant slalom. Vonn's thumb will be in a splint but she should be able to grasp her ski pole.
"Everything went really well and I couldn't be more thankful for the care that I've received," said Vonn, who has captured gold medals in super-G and downhill in Val d'Isere, France. "The support from my fans has been awesome. I'm looking forward to returning to Worlds and challenging for another medal."
The United States also announced the roster for Thursday's team events. The men's and ladies' squads includes Olympic gold medalist Julia Mancuso, and Olympians Stacey Cook and Jimmie Cochran. Also representing the United States will be Andrew Weibrecht, Tim Jitloff and Hailey Duke.
