Beijing: Downhill World champion Lindsey Vonn will miss the Sochi Winter Olympics due to a knee injury, she announced on her Facebook page.
"I am devastated to announce that I will not be competing in Sochi," the American said, reports Xinhua.
"I did everything I possibly could to somehow get strong enough to overcome having no ACL but the reality has sunk in that my knee is just too unstable to compete at this level.
"I'm having surgery soon so that I can be ready for the World Championships at home in Vail next February."
The 29-year-old has 59 World Cup race victories to her credit and is the reigning Olympic downhill champion. She badly injured her knee while competing in a Super-G at the World Championships in February last year.
After reconstructive surgery on the joint and a lengthy layoff, Vonn returned to World Cup competition at Lake Louise, Canada in early December, but she injured the same knee again while training in Colorado in November.
At Lake Louise, Vonn was 40th in the first downhill, 11th in a second downhill and fifth in a super-G.
