Bode Miller, who is recovering from back surgery, crashed out of the World Championships super-G race Thursday after tumbling backwards down the hill and slicing his leg open.
The American was having the fastest time of the early racers when his left arm slammed into a gate at about 100 km/h, twisting him around and sending him spinning down the hill.
Both skis came flying off as Miller slid a long way down the Birds of Prey course.
He was able to get up and coast down to the finish where he received a standing ovation in what could his last appearance in the worlds.
Miller is one of the most successful ski racers in US history. At 37 years and 115 days old, he was hoping to become the oldest gold medallist in an individual event at the World Championships.
