DENVER -- Olympic downhill champion Lindsey Vonn was hurt Tuesday while training at the U.S. Ski Team Speed Center at Copper Mountain, one week before she was due to begin official downhill training for World Cup races at Beaver Creek.

Ski Racing magazine reported she injured a knee, but U.S. Ski Team spokesman Tom Kelly was unable to confirm that. Kelly could say only that he was aware that she had crashed during training and was being "evaluated."

Vonn's public relations manager, Lewis Kay, had little to add.

"Lindsey crashed earlier (Tuesday) morning while training at Copper Mountain in Colorado," Kay said in an email. "She was not admitted to the hospital and is currently being evaluated by Dr. (Bill) Sterett back in Vail. We expect to have clarity on the situation in the next 24 hours.

"We will provide updates when we know more and appreciate your patience."

Kay would not confirm a knee injury, but Sterett is an orthopedic surgeon, and he repaired Vonn's right knee in February.

Vonn blew out her right knee last February in a crash racing super-G at the world alpine championships in Schladming, Austria. Early this month she said her knee felt great, and said she believed she was ready to start winning races. The women will race downhill, super-G and giant slalom at Beaver Creek, Nov. 29-Dec. 1.
