Two-time reigning figure skating world champion Shoma Uno will miss the ISU World Team Trophy this week after hurting his right ankle, the Japan Skating Federation said Monday.

Uno has been ruled out of the competition starting Thursday at the Tokyo Metropolitan Gymnasium as he needs two weeks to nurse his ligament and cartilage damage.

"I did my best with both my training and treatment, but I could not get myself back to the level to compete," the 25-year-old said in a JSF statement.

Shun Sato will replace Uno for Japan as the host bids to win the World Team Trophy for the first time in three meets by overcoming five rivals, including the United States and Canada.
