Great Britain's slopestyle skier James Woods has admitted that he is not "100%" fit ahead of the competition which begins on Thursday.
Woods suffered a crash in training earlier in the week, and while he has recovered well from his injuries he is concerned that he might not be at his best.
"I'm not 100%, some things are hurting," he told BBC Sport. "I am a little upset because I wanted to be given the opportunity to perform at 100% and I have to hope it doesn't hold me back too much.
"It's the same for a lot of competitors and I'm just going to give it all I can."
GB's only medal so far is in the women's snowboard slopestyle, where Jenny Jones took bronze.
