Alt-rock band Bring Me The Horizon were forced to cancel the last two shows on their U.S. tour as vocalist Oli Sykes recovers from a ruptured vocal cord.

The British group was slated to perform in Pheonix, Arizona tonight and in Las Vegas, Nevada tomorrow night.

“I’m gutted to announce we have to cancel the remainder of our American out, Sykes said in a statement earlier today. “I’ve ruptured my right vocal cord, and I’ve been told if I don’t rest it immediately, I’m in serious danger of doing permanent damage.

“I’ve been trying my best to fulfill our commitments as I really hate letting you guys down, not to mention these shows have been literally the most fun ever. But at this point, me singing would be the equivalent of a footballer running on a broken leg. Once again, I’m so sorry. I hope you all understand.”

He noted that the band is working on plans to come back to Phoenix and Las Vegas this year to “make it up to everyone who missed out.” The opening band, The Fever 333, assured Arizona fans that they will be back to the state on March 23 at Rock 102.1 KFMA Day and told Vegas fans “there’s a fever coming…”

Ticketholders can receive refunds at point of purchase.

Bring Me The Horizon just dropped the album amo earlier this year, featuring singles “mother tongue,” “medicine,” “nihilist blues” featuring Grimes, and the Grammy-nominated song “MANTRA.” The record follows 2015’s That’s The Spirit and Sempiternal from 2013.

The band is due to play next in London on February 19 before heading to Mexico in March. After a string of shows overseas, they’ll head back to the states for a handful of festivals this summer including Jacksonville’s Welcome To Rockville, North Carolina’s Epicenter, and Sonic Temple Festival in Ohio.
