KRASNAYA POLYANA, Russia (AP) Austrian snowboarder Adrian Krainer withdrew from the Olympics after suffering an inch-long cut on his chin and hurting his heels during training Friday on the rugged slopestyle course.

Krainer finished last in his Thursday qualifying heat at Rosa Khutor Extreme Park. He needed a top-four finish in Saturday's semifinals to reach the medal round.

Earlier this week, Norway's Torstein Horgmo broke his collarbone and American Shaun White withdrew from slopestyle, citing the danger of the course.

After several accidents during training, the riders had fewer problems when competition opened Thursday. Canada's Max Parrot scored a 97.5 to lead eight of the 29 men who scored in the 90s.
