Cube Entertainment said Jang Hyun Seung got emergency care and will go to the hospital shortly.

They also added, "Their new song 'Good Luck' has a lot of powerful dances so we're worried about his performance, but we will put his treatment first and watch how he does."

On June 19, Jang Hyun Seung posted on his Instagram, "I hurt my ankle during a rehearsal... I can still dance without putting pressure on my leg! I will cure as soon as possible."
