Steven Tyler

Aerosmith have cancelled their remaining tour dates as frontman Steven Tyler battles “unexpected medical issues”.

The rockers are currently in the middle of the South American stretch of their Aero-Vederci Baby Tour, but the four remaining shows in September and October (17) have been axed as Tyler undergoes medical treatment.

“Unfortunately, due to unexpected medical issues, lead singer, Steven Tyler, is seeking immediate care and has been advised by his doctors that he cannot travel or perform at this time…,” a message on Twitter reads.

“Steven is expected to make a full recovery,” the message continues. “With proper rest and treatment he will be back on his feet soon, rocking the world.”

The details of the medical issues remain under wraps, but Tyler has assured fans they are not life-threatening: “I’m very sorry and feel like I’ve let you down,” he writes in a statement. “I won’t be able to continue the last four shows of this tour.

“I flew back to the U.S. on doctor’s orders last night after the show in Sao Paulo. Please not to worry. I am not in a life-threatening condition, but I need to deal with this right away and get some rest and medical care immediately in order to sustain and maintain my future performances.

“I promise I’ll be back. Unfortunately, health does not wait and it’s something even I can’t schedule around our shows. As they say, ‘We humans make plans, and God laughs’. I love you all and will be back with you soon.”
