The Vancouver gold medalist's rep, who still did not know the extent of Vonn's injuries, said in a statement, "Lindsey was involved in a crash in today's World Championship Super G race in Schladming, Austria. She is currently being evaluated and we will provide an update when it becomes available."
Shortly after the incident, the Alpine Press Tweeted, "Doctor on hill with @linseyvonn suspects tibial plateau fracture. We'll await official diagnosis following X-rays and MRI."
A tibial plateau fracture is a break in the shinbone near the knee and affects stability and motion.
According to NBC News, Vonn, 28, lost her ski after a tough landing and slid off course into a gate before she came to a stop. See video of her crash below.
"Made awkward landing on the jump that has given many skiers here trouble. Right knee/ankle bent awkwardly. Looked scary," Tweeted Alex Goldberger, of NBC.
The doctor examined her at the scene for more than 10 minutes before Vonn was taken to the hospital for further evaluation.
Vonn, who late last year revealed to PEOPLE that she suffers from depression, was trailing World Cup points leader Tina Maze of Slovenia by only 0.12 seconds before the crash, said NBC.
Because of fog, the race had already been delayed 3½ hours and was then resuming after a 15-minute delay.
