It's been belatedly reported that Ailee injured her ankle while preparing for her comeback prior to her stage on 'Music Bank'. 

Her agency YMC Entertainment stated, "After falling on the 10th, Ailee injured her left ankle. Though she's received treatment, she's still in pain. However, because she strongly desired to go through with her comeback and the fans who've waited for her new album, she forced her way for her comeback with 'U&I'."
