Fans captured the dramatic moment, which shows Clifford fleeing the stage during a performance of their hit, “She Looks So Perfect.”
Bandmate Ashton Irwin then told the crowd that the show had to be stopped because of the accident.
“Michael has hurt himself so we will not be continuing the show right now,” Irwin said. “Just want to say thank you so much for coming. He is OK. You guys have been the best crowd we could ask for tonight. Thank you so much.”
Clifford took to Twitter to assure fans that he's OK, and to show them the extensive bandages that kept him from doing an encore.H/T MTV | Screengrab via 5 Seconds of Summer Subs/YouTube
