The band was playing a concert at Wembley Arena Saturday when the accident occurred. His bandmate Ashton Irwin announced the band would not be finishing their show after Clifford walked off stage rubbing his face with a towel.

But the show must go on, and the band is expected to play Wembley again Sunday evening. "Feeling loads better and my face is fine :)," Clifford tweeted Sunday morning. "Excited for the show tonight."
