Skier Lindsey Vonn was taken off a mountain by helicopter after she crashed and suffered a knee injury during a Super-G race on the opening day of the alpine skiing world championships in Schladming, Austria.

Peter Schroecksnadel, president of the Austrian ski federation, said that doctors had told him that Vonn tore cruciate and lateral ligaments. “That’s the only injury she has, nothing besides this,” Schroecksnadel said.

The four-time overall World Cup champion was injured when she struck a gate after losing her balance as she landed after a jump. She was treated on the slope for 12 minutes, according to the Associated Press, then was lifted off the mountain. The crash comes almost exactly one year from the beginning of the Winter Olympics in Sochi, Russia.

Vonn, 28, was trailing Tina Maze of Slovenia, the eventual winner, by 0.12 seconds at the time of her run.

The race had been delayed over three hours because of fog. “It’s not a very difficult course,” Switzerland’s Fabienne Suter told BBC.com, “but in some parts you couldn’t see anything.”

In a YouTube video of the crash, her right knee appears to awkwardly bend inwardly as she lands and then she collapses.

Vonn was troubled by intestinal injuries that sidelined her until last month and has suffered a number of injuries over her career. “Finally,” she said Sunday, she was healthy entering this competition. “I’m definitely getting ready to get my game face on.”
