Aerosmith’s Steven Tyler suffered head, neck and shoulder injuries in a tumble from the stage at a South Dakota show, a concert spokesman said Thursday, and the audience thought it was part of his hipshaking act until he didn’t get up.

Aerosmith has postponed its Sunday show at Verizon Wireless Virginia Beach Amphitheater because of an unspecified “artist injury.“ The band, on tour this summer with ZZ Top, also postponed last night’s show in Cincinnati and tonight’s gig at Hersheypark Stadium in Pennsylvania. A rescheduled date is expected to be announced soon. Previously purchased tickets will be honored.
