(CNN) -- Lindsey Vonn's knee troubles apparently are too much to overcome in time for Sochi.

Vonn, the reigning Olympic and World Cup downhill skiing champ, will not compete in next month's Winter Olympics, according to a post Tuesday on her official Facebook page.

"I am devastated to announce that I will not be able to compete in Sochi," Vonn's post read.

The news comes 11 months after she hurt her right knee knee at the world championships. The four-time World Cup overall champion underwent reconstructive surgery but aggravated the problem in a crash during training in November.

The American skier, who is dating golfer Tiger Woods, may have resigned herself to watching the Winter Olympics from the sidelines but the Minnesota athlete is still looking for a silver lining.

"On a positive note, this means there will be an additional spot so that one of my teammates can go for gold," she added.

"Thank you all so much for all of the love and support. I will be cheering for all of the Olympians and especially Team USA!"

Bill Marolt, president of the U.S. Ski and Snowboard Association, supported Vonn's decision and said in a statement: "In looking ahead, I have every ounce of confidence that Lindsey will be in the starting gate next World Cup season ready to compete.
