Lindsey Vonn had to be carried from the women's super-G on a rescue sled after crashing out in El Tarter, Andorra on Saturday.
Vonn, the leader in the overall and super-G standings, slid off the course midway through her run, and came to a stop without making contact with any perimeter barriers.

Vonn remained still before being attended to by course staff, who then carried the American down to the finish on a sled.
The extent of any injury sustained remains unknown, with fans expressing their sympathy on Twitter for Vonn, who was forced to miss the Winter Olympics in Sochi in 2014 with a knee injury.
