In the Audi FIS Alpine Ski World Cup on Saturday, Lindsey Vonn suffered three fractures in her knee in an ugly crash that will ultimately end her season. Vonn crashed during the Women's Super G race and had to be taken off the mountain via rescue sled.

In a Facebook post, Vonn explained her circumstances and her future.

"Today I am making the difficult decision to end my season and leave the World Cup circuit due to an injury I suffered last Saturday. Because I am currently leading the Overall World Cup standings, this is one of the toughest decisions of my career," Vonn said.

With the Olympics just a few years away, questions were raised about whether she would be healthy enough to compete at that time?

"I went to Barcelona where more precise MRI and CT equipment was available and scans were performed on Tuesday morning. Those images showed that there was not just 1 hairline fracture, but in fact 3. And the fractures are not hairline, but instead they are significant enough that they are not sufficiently stable to permit me to safely continue skiing," Vonn said. "Further damage any of the fragments could result in a serious surgery that would risk my future in ski racing. With the World Championships in St. Moritz next year and the Winter Olympics in South Korea the following year, I cannot take that risk."
