Marcel Hirscher of Austria edged closer to a second straight overall World Cup title on Thursday when organizers cancelled a super-G race after only 10 of 27 racers started in Lenzerheide, Switzerland.

Already delayed 3 ½ hours by bad weather, the men's race was called off 45 minutes after Klaus Kroell of Austria crashed into the safety nets.

The Austrian ski team said Kroell had broken his upper left arm and will undergo surgery as soon as possible.

The 32-year-old Kroell was airlifted by helicopter to a hospital in Chur after being treated for almost 45 minutes at the side of the course.

Kroell went headlong into safety nets after losing his racing line when he was launched into the air from a ridge approaching a right-hand turn.

On Wednesday, Kroell lost his season-long World Cup downhill title to Aksel Lund Svindal when the final race was cancelled because of thick fog.

The women's super-G was also cancelled Thursday. That gave the season-long super-G title to Tina Maze of Slovenia, who had already won in the overall and giant slalom standings.

Maze could only have been caught by Julia Mancuso. The American's head coach, Alex Hoedlmoser, said the steep, twisting course was "too dangerous" to race on.

"The wind was blowing the snow across the track and you couldn't really see enough. The conditions on the top were just not good enough," Hoedlmoser said.

In a difficult World Cup finals week for race organizers, the weather helped decide season-long titles for a second day.

Aksel Lund Svindal of Norway had already won the men's super-G title but was prevented from scoring race points in his overall pursuit of Hirscher.

Svindal trails Hirscher by 149 with the Austrian technical specialist's best two events, giant slalom and slalom, remaining at the weekend. Race wins award 100 points.

The Norwegian challenger all but conceded the overall title Wednesday after thick fog forced the downhill to be cancelled, giving him the discipline title.

The cancelled women's downhill gave the title to American star Lindsey Vonn, whose season was ended by injury last month. She stayed one point ahead of Maze, who was denied a chance at sweeping all five women's World Cup trophies.

Fog, falling snow and cross winds on the upper slope caused problems Thursday, after the lower slope was shrouded in fog 24 hours earlier.

The men's super-G  was halted by cross winds after the first racer, Gauthier de Tessieres of France, came down.

De Tessieres recovered his balance well after being launched into the air midway through his run, at a ridge approaching a right-hand turn.

Kroell crashed out at the same spot.
