Olympic downhill champion Lindsey Vonn crashed Tuesday on a training run at Copper Mountain in Colorado and was taken to the hospital for evaluation.
Vonn's condition was not immediately clear. She left the slope on a sled.
The U.S. Ski and Snowboard Association posted a statement on its website later Tuesday that read in part, "(Vonn) was not admitted to the hospital but was undergoing further evaluation, as is typical after a crash."
Vonn, 29, was preparing to return to competitive racing after a serious knee injury this year.
Vonn was airlifted to a hospital in February after she landed heavily on her right knee on the opening day of the Alpine Ski World Championships in Austria. She underwent surgery for knee reconstruction after she tore her ACL and MCL.
Vonn, a four-time overall world champion, became the first American woman to win the Olympic downhill title at the Vancouver Games in 2010.
Vonn had planned to return at the World Cup event in Beaver Creek, Colorado on Nov 29, and then be ready for the Sochi Olympics in February.
