Michael Clifford, a guitarist with 5 Seconds of Summer, is due to join the band for their final London show despite burning his face during a pyrotechnic mishap.
The band had been playing at Wembley Arena when the 19-year-old walked too close to the on-stage flamethrowers and set part of his hair on fire.
He was filmed quickly putting a towel to his smoke-engulfed head, but was left with burns to his face and last night's concert was cut short.
Later he tweeted a picture of his face in bandages, saying he was "doing ok".
After receiving clearance from doctors, the British group are set to return to the stage tonight - but the pyrotechnics will not be joining them.
An official spokesman for 5 Seconds of Summer said: "Michael is recovering well after being given the all-clear by doctors.
"He will join the band on stage tonight at the SSE Arena for their third and final London show.
"Michael and the band would like to thank all the fans, well wishers and particularly last night's audience for their support. There will be no pyrotechnic production for the show this evening."
The incident followed news that American rockers Foo Fighters had to cancel two dates of their European tour after singer Dave Grohl fell off stage during a performance and broke his leg.
