It's been reported that SKE48 member Matsumura Kaori has sprained her right ankle after losing her footing on a step. 

Matsumura just held her graduation concert on February 5 at Omiya Sonic City. On her blog, she shared that she injured her ankle on her way from Tokyo to Nagoya. She is currently unable to walk without crutches. As a result, her birthday event, which was scheduled to be held on February 12 at SKE48 Theater, will be postponed.
