According to the USA Today, Lindsey Vonn's comeback for the Winter Olympics may be in jeopardy after she crashed in training at Copper Mountain, Colo., on Tuesday.

"The U.S. ski team confirmed that Vonn, who is trying to come back from major knee surgery, crashed Tuesday and is being evaluated.

It is not clear whether she re-injured her right knee. She tore the ACL and MCL in that knee and fractured her tibia in a brutal crash on Feb. 5. Vonn was scheduled to return to competition on Nov. 29 in Beaver Creek, Colo." USA TODAY
