Olympic gold medallist Lindsey Vonn has been airlifted to hospital after a serious crash on the opening day of the Alpine Skiing World Championships in Austria.
The crash happened shortly after 14:15 GMT on Tuesday during the women's super-giant slalom event.
A helicopter was immediately called with medics treating the American on the slope for 12 minutes.
Vonn, 28, is also a four-times overall World Cup champion.
She was 0.12 seconds outside the time of race leader and eventual winner Tina Maze of Slovenia when she fell.
The 2009 world downhill and super-G champion appeared to land on the side of her ski after a jump and flipped over before crashing into a safety gate.
The race, which had been delayed by three and a half hours because of fog, continued after Vonn was taken to a local hospital but Maria Hoefl-Riesch and Anna Fenninger also dropped out after mistakes on their runs.
Vonn made her World Cup debut aged just 16 in 2000 before competing at the 2002 Winter Olympics in Utah. In 2008, she claimed her first World Cup title to become only the second American woman to lift the trophy.
The Minnesota-born skier went on to secure gold in the downhill event at the Vancouver Winter Olympics in 2010 and also took bronze in the super-G.
Vonn's request to compete in a men's World Cup downhill ski race was rejected by the International Ski Federation (FIS) last year.
