KRASNAYA POLYANA, Russia – Shaun White's quest for two golds in one Olympics ended Wednesday.

The American snowboarder announced in a statement on Today that he would not compete in slopestyle as he had previously planned. The two-time defending gold medalist in the halfpipe, White is seeking to become the first American man ever to win an event in three consecutive Winter Olympics.

"The difficult decision to forego slopestyle is not one I take lightly as I know how much effort everyone has put into holding the slopestyle event for the first time in Olympic history, a history I had planned on being a part being a part of," White said in a statement.

"With the practice runs I have taken, even after course modifications and watching fellow athletes get hurt, the potential risk of injury is a bit too much for me to gamble my other Olympics goals on."

He was not favored to win gold in slopestyle and faced a challenge to even medal. Canadian Mark McMorris remains the gold medal favorite despite breaking his rib at the X Games last month. Several other Canadians and Norwegians are expected to challenge for a spot on the podium.
