It happened about midway through the course when Jansrud lost control and slid into the fence on the side of the slope, twisting and flipping over after the collision. Jansrud was clearly in pain as he grabbed his knee once he finally came to a stop.
Jansrud is a well-decorated skier, having won several World Cup races during his career in addition to a silver medal in the giant slalom at the 2010 Olympics. According to NBC Sports, he had previously stated to Norwegian media that this was likely to be his last year on the World Cup circuit. Whatever happens, we wish Jansrud the best.
