The announcement followed an incident in Dallas Friday night during which lead singer Caleb Followill left the stage, complaining of the heat and a failing voice. A subsequent show in The Woodlands, Texas, was canceled Sunday.
"We are so sorry to say Kings of Leon are canceling their entire U.S. tour due to Caleb Followill suffering from vocal issues and exhaustion," the group said in a statement Monday. "The band is devastated, but in order to give their fans the shows they deserve, they need to take this break."
Followill said the U.S. dates cannot be rescheduled due to the band's international tour schedule. Tickets will be refunded at point of purchase, he said. Tickets purchased online or via phones will be automatically refunded.
The band will resume touring in Canada at the Rogers Center in Vancouver, British Columbia, on Sept. 28, he said. That show was originally scheduled for Sept. 14.
