According to Deadline, stuntman John Bernecker suffered a head injury after falling more than 20 feet onto a concrete floor. “We are saddened to report that John Bernecker, a talented stuntman for The Walking Dead and numerous other television shows and films, suffered serious injuries from a tragic accident on set,” AMC said in a statement Thursday. “He was immediately transported to an Atlanta hospital, and we have temporarily shut down production.
