His hair caught fire during a show in London last week when he got too close to a pyro, forcing the band to end their encore early. That's led them to scrap pyrotechnics for future performances.

Clifford jokes with radio KIIS1065: "I was shredding so fast that my fingers caught on fire and burnt me." He continues: "I'm all good - luckily it wasn't any worse. I sprained my ankle on stage two weeks before that then I got a bad back, so I'm not doing well these past few weeks."
