Popular World Cup Champion Lindsey Vonn Airlifted to Hospital After Skiing Accident -- Here Are the Pics and Video

SCHLADMING, Austria (TheBlaze/AP) -- A dangerous accident during a winter sports event has sent another athlete to the hospital within the last two weeks. Lindsey Vonn crashed during the super-G (a super giant slalom) Tuesday and was taken to a hospital by helicopter after apparently hurting her right knee at the world championships.

The four-time overall World Cup champion lost balance on her right leg while landing after a jump. Her ski came off immediately, and Vonn slid off course and hit a gate before coming to a halt.

Watch the terrifying accident occur in this footage:

She received treatment on the slope for 12 minutes before going to the hospital. Her U.S. team had no immediate information on her condition.

Snowmobiler Caleb Moore was sent to the hospital a couple weeks ago after an accident at the Winter X games and underwent surgery for a heart contusion. Moore died from his injuries a few days after the surgery.

Vonn's crash came almost exactly one year before the start of the 2014 Winter Olympics in Sochi, Russia.

Vonn returned to the circuit last month after an almost monthlong break from racing to fully recover from an intestinal illness that put her in a hospital for two days in November.

Vonn trailed race winner Tina Maze of Slovenia by 0.12 seconds shortly before the crash.

The race, which was postponed for 3 1/2 hours because of fog, resumed after another 15-minute delay. Several racers struggled with the conditions.

"It's not a very difficult course, but in some parts you couldn't see anything," Fabienne Suter of Switzerland said.
