Kings of Leon have cancelled their US tour after singer Caleb Followill was hit by vocal problems and exhaustion.
The cancellation comes three days after Caleb left the stage mid-show in Dallas, due to what he called "excessive" and "unbearable" heat.
"Thanks to all our true fans for understanding and helping us through this hard time," the frontman said on Twitter.
His brother and bandmate Jared also acknowledged on Twitter the band had "internal sicknesses and problems" that go beyond dehydration.
Meanwhile, a spokesperson said the band are "devastated, but in order to give their fans the shows they deserve, they need to take this break".
They will return to the road in Vancouver, on September 28.
The cancelled shows will not be rescheduled.
