World Wrestling Entertainment Inc. subjects professional wrestlers to “extreme physical brutality,” but tries to keep the performers unaware of the irreversible brain and body damage that can result, a proposed class-action filed in Oregon federal court by a former wrestler contends.

With scripted moves including the “Brain Buster” and the “Facebreaker,” WWE wrestlers are encouraged to endure—and inflict—blows from chairs, chain and garbage cans plus head-first slams to the floor, according to a complaint filed Oct. 23 in U.S. District Court for the District of Oregon.
