The pop band 5 Seconds of Summer (5SOS) cut short its London show Saturday, after guitarist Michael Clifford suffered burn injuries during an onstage accident. The 19-year-old musician suffered burns on his head when he accidentally walked into a pyrotechnic display, Billboard reported. The band was playing “She Looks So Perfect” during its second night performance at Wembley Arena in London when the accident happened. 

A clip captured by a fan showed Clifford rushing offstage while grabbing a towel to cover a side of his head after his hair and face got singed. After the incident, bandmate Ashton Irwin told the crowd: “Michael has hurt himself so we will not be continuing the show right now. 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.”

The injured guitarist took to Twitter after the concert, posting a photo of his bandaged face, not only to apologize for not finishing the concert but also to assure fans that he is OK: “ … Sorry I couldn’t finish the encore, but at least I look like two face. thanks for worrying every1 x.”

According to E! News, Clifford’s accident sparked concern among the musician’s friends and fans online, with #GETWELLSOONMICHAEL becoming a trending topic on Twitter. Even ex-girlfriend Abigail Breslin sent Clifford a tweet after the accident, writing: "Hey @Michael5SOS. Heard about your accident. Wishing you a speedy recovery and hope you'll be back rockin' it on stage very soon!"

Meanwhile, a representative from 5SOS told MTV on Sunday that Clifford is healing and recovering well after being given the all-clear by doctors. Through it all, the 5SOS guitarist maintained his sense of humor, trying to make light of the incident and thanking fans for their love and support. Clifford then joined the band onstage Sunday for the third and final show of the London leg of their “Rock Out With Your Socks Out” concert tour.  

The pyrotechnic special effects that injured Clifford were removed from Sunday’s show.
