+++ Yuzuru(HANYU)'s injury update +++ Mar. 21 on Pigeon Post
Brian(ORSER) suggested that he should go back to Japan in order to undergo tests on left knee and right ankle injuries. Its results indicate a left knee Patellar tendinitis("jumper's knee"), which requires 1 month of rest; but his right ankle - the sprain has been concerning him for a long time since childhood - he sprained it again in warm-up 6 minutes before Worlds FS, which is not in critical condition, fortunately. Yuzuru is going to prepare for the next season, work on rehabilitation "little by little" (as he confessed that he "should have taken a slow start," after Worlds FS). He withdrew from World Team Trophy in Japan next month.
