Lindsey Vonn, U.S. gold medalist in downhill at the 2010 Winter Olympics -- and the significant other of world No. 1 golfer Tiger Woods -- announced this morning that she will not be able to compete in the 2014 Olympic Games in Sochi, Russia, set to start in February.
The 29-year-old Vonn revealed the news via her Facebook page  with this post:
I am devastated to announce that I will not be able to compete in Sochi. 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. On a positive note, this means there will be an additional spot so that one of my teammates can go for gold. 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!
Vonn initially suffered a tear to her anterior cruciate ligament and medial collateral ligament in her right knee, with a tibial plateau fracture after a crash in the Super G in the first race of the 2013 World Championships in Schladming, Austria, last February.
Vonn worked hard to get back on the slopes hoping to be in Sochi, but suffered a set back after another crash during a practice run in Colorado in November. Vonn tried to race with the pain, but re-injured the same knee on Dec. 21 in Val d' Isere, France.
According to a statement released by her publicist,  "an MRI showed an MCL sprain, which coupled with the torn ACL, has made it impossible to stabilize her knee and be ready to safely ski again next month."
