Olympic men's figure skating champion Yuzuru Hanyu could be out of action for three weeks after suffering cuts and bruises in a frightening on-ice collision at the Cup of China, the Japan Skating Federation said Monday.

Hanyu, who became the first Asian man to win figure skating gold at the Sochi Winter Olympic Games in February, was left with blood streaming from his chin after slamming into China's Yan Han during free skate warm-ups in Shanghai on Saturday.

The 19-year-old was left woozy by the collision, which happened as he and Yan glided backward into each other, and had to be helped off the ice by trainers. Hanyu returned to perform with a bandage wrapped around his head and tape under his chin.

The ferocity of the impact took its toll, however, and the unsteady skater fell five times in his routine, though he was still able to claim second place.
