The talented Canadian is no stranger to big kickers, or to big events - his numerous gold medals in both big air and slopestyle at the X Games having made him the man to beat in recent years - which is why this nasty break came as a complete surprise, something of a freak accident.
"It was something of a freak accident"
McMorris initially seems to land his trick - a frontside 1440 triple cork - pretty cleanly, but then sat back.
As he slid down the landing, the toe edge of his board dug in, catapulting him forward and apparently snapping his right femur. It's hard not to wince watching the footage.

McMorris was immediately stretchered off and is currently preparing to undergo surgery to insert pins into his broken bone in a California hospital.
It's estimated he won't be able to ride for the next six months, a massive shame given that his season had started so well. Everyone at Mpora is wishing McMorris a speedy recovery.
