Aerosmith announced the cancellation of the remainder of its summer tour Thursday, more than a week after the band’s lead singer tumbled off stage in South Dakota. “Due to injuries Steven Tyler sustained last week when he fell from the stage during a concert in Sturgis, South Dakota, doctors have advised the lead singer to take the time to properly recuperate from the accident that resulted in a broken shoulder and stitches to his head,” the band said in a statement. The accident happened August 5 during a concert at the Sturgis Motorcycle Rally in western South Dakota.
