Aerosmith has canceled the band's first batch of Las Vegas residency dates due to frontman Steven Tyler entering a treatment program.
"As many of you know, our beloved brother Steven has worked on his sobriety for many years," the "Dream On" rockers wrote in a social media statement posted Tuesday.
"After foot surgery to prepare for the stage and the necessity of pain management during the process, he has recently relapsed and voluntarily entered a treatment program to concentrate on his health and recovery."
As such, Aerosmith won't be playing the Vegas dates scheduled for June and July while Tyler "focuses on his well-being."
"We are devastated that we have inconvenienced so many of you, especially our most loyal fans who often travel great distances to experience our shows," the statement read. "Thank you for your understanding and for your support for Steven during this time."
Those who purchased tickets to the affected shows will receive refunds.
Aerosmith plans to resume the residency in September.
