Sochi 2014 bronze medallist Mark McMorris has sustained several injuries in an accident during a back-country snowboarding trip in Whistler in British Columbia on Saturday (March 25).

The Canadian's injuries include a fractured jaw, fractured left arm, ruptured spleen, a stable pelvic fracture, rib fractures and a collapsed left lung according to Canada Snowboard's team physician, Rodney J French.

After being airlifted to Vancouver General Hospital, McMorris underwent a successful "minimally invasive" surgery to control bleeding from the spleen on Saturday.

The 23-year-old, who won slopestyle bronze at Sochi 2014, was then operated on for a second time on Sunday (March 26) to repair both his jaw and upper arm fractures.

“While both the mandible and humerus fractures were complicated injuries, the surgeries went very well and both fractures are now stabilised to heal in excellent position," said French.

"It is too early to speculate on a timeline for Mark's recovery.”

The accident is a sour end to what has been a successful season for McMorris.

He won two X Games bronze medals in Aspen and two crystal globes, one in big air and another as the overall International Ski Federation (FIS) Snowboard Freestyle World Cup champion.

It has been confirmed by Canada Snowboard spokesperson Brendan Matthews that McMorris was filming with his brother Craig and friends when he was involved in the crash.

"He hit a jump and just went a little too far to the left and it was really unfortunate as he ran into some trees," Craig McMorris told CBC Sports.

"It was a super freak accident.

"Mark never makes mistakes, but he made just a tiny mistake and went too far to the left.

"It was awful."

Canada Snowboard’s executive director, Patrick Jarvis, is hopeful that McMorris will make a full recovery in time for competition in the build up to Pyeongchang 2018. 

"We fully support Mark and he is already under the incredible care of the staff of the Vancouver General Hospital,” said Jarvis.

"Mark has shown incredible resilience and commitment to recovering from injury and we know that Pyeongchang 2018 will be a strong motivation for his comeback."

Back-country snowboarding is usually conducted in a rural region over ungroomed and unmarked slopes.

Despite the injuries, McMorris was one of two athletes provisionally named to Canada's Pyeongchang 2018 snowboard team today alongside Max Parrot.
