The Sochi Olympics has lost a major American star.

Skier Lindsey Vonn announced that she will not compete in the Olympics next month on her Facebook page.  Vonn tore her ACL in a serious crash at the 2013 World Championships in February of 2013.  She re-injured the same knee in November.

Vonn won the Gold Medal in the 2010 Vancouver Olympics in the Downhill.  She also won the bronze in the Super-G.

Lindsey Vonn has gotten a lot of media attention outside of her skiing career.  She's appeared on numerous talk shows and in Sports Illustrated's Swimsuit Edition.  For the past year, she has dated golfer Tiger Woods.
