Tyler's doctors have told him he needs more time to recuperate
Rock band Aerosmith have called off the remainder of their summer tour in the wake of singer Steven Tyler's on-stage accident last week.
The group made the announcement "with great regret". "Words can't express the sadness I feel for having to cancel this tour," said guitarist Joe Perry.
Tyler, 61, suffered head and shoulder injuries after falling off stage at a concert in South Dakota.
Aerosmith had been scheduled to tour Canada and the US until 16 September.
Ticket refunds for the cancelled tour dates will be available at point of purchase.
Tyler's accident occurred in Sturgis, South Dakota on 5 August at a concert that had already been delayed by heavy thunderstorms.
He was subsequently airlifted to hospital before travelling to Boston to consult with his own doctors.
Doctors advised him he needed time to recuperate from the mishap, which left him with a broken shoulder and stitches to his head.
"We never anticipated this tour coming to such a swift and unfortunate ending," said guitarist Brad Whitford.
"Our thoughts and prayers go out to Steven for a speedy recovery and return to good health."
Speaking on Thursday, the singer said he had been doing "the Tyler shuffle" when he slipped and fell off the edge of the stage.
"I'm plain grateful that I didn't break my neck," he said in a statement, thanking the Sturgis police department, medical staff and Aerosmith crew members.
