Kohei Uchimura was diagnosed with torn ligaments in his left ankle that will require two to three weeks' recovery, a Japan Gymnastics Association official said Tuesday.
Uchimura withdrew from the ongoing artistic gymnastics world championships Monday after he injured himself during a vault landing in a qualifying session, ending his bid for a seventh straight individual all-around title.
Doctors at a hospital in Montreal found no bone fractures and the 28-year-old will not undergo surgery, said Hisashi Mizutori, JGA's chief director of the men's team.
