Aerosmith had to postpone three dates because singer Steven Tyler was suffering from an unspecified injury. The group couldn’t make their July 1st show in Cincinnati, their July 3rd show in Hershey, Pennsylvania or their concert on Sunday in Virginia Beach, Virginia. Reuters speculates the injury is a pulled muscle since fans at the band’s June 29th performance said it appeared as though Tyler had pulled a leg muscle during the show. As of press time, the group is scheduled to perform tonight in Raleigh, North Carolina. The concert will be the first to feature guitarist Brad Whitford, who needed surgery after bumping his head while exiting his Ferrari.
