KRASNAYA POLYANA, Russia -- Norwegian snowboarder Torstein Horgmo, a medal contender in slopestyle, is out of the Olympics after breaking his collarbone on a training run Monday.

"Falls are part of our sport, but the timing is awfully bad," Horgmo said, according to a translation of a release from Norway's press office.

Injuries are taking their toll on the event, which is new to the Olympics this year. Gold medal favorite Mark McMorris of Canada crashed on a rail in the X Games slopestyle final last month, breaking a rib.

He said Sunday that he's on a "good road to recovery" just eight days since the injury. ... "Just trying to get as good as I can before we start the madness."

In the release, Olympic doctor Ellen Moen said Horgmo's fracture is "uncomplicated" but that it would be impossible to train and compete with the injury.

Moen said Horgmo, who said he's eager to get back on the board and "have fun" again, also suffered a concussion; the press office said he would not be available to speak publicly Monday.

Horgmo fell on a rail at the top of the slopestyle course and was treated at the scene and taken to the hospital by ambulance.

"I saw that he fell over the rail and trashed pretty hard," said teammate Staale Sandbech, who calls Horgmo a tough Viking. "He tried a really hard trick (switch hardway backside 270), probably the hardest trick you'll see all day. He was transferring from one jump to another rail."

International ski federation official Roberto Moresi, the assistant snowboard race director at Sochi, told The Associated Press that organizers had responded to feedback from the athletes and were trimming some jumps at the top of the course "in order to make it more smooth."

Moresi said the course wasn't a factor in Horgmo's crash, saying it happened because "he was just trying a really hard trick."

The injury at the Rosa Khutor Extreme Park came during training, a time for athletes to test the course. Canada's Sebastien Toutant said of the course: "It's all right. It's big. I think they need to work on the jumps a bit but it's all right. We will keep riding it."

Asked about safety on the course's jumps, Toutant added: "They definitely have the slope. We have big air time, but it's air time dropping down. It is like jumping out of a building. I should put on my Canadian flying squirrel suit."
