Retired professional wrestlers are suing World Wrestling Entertainment, also known as WWE, for head injuries they claim to have suffered in the ring. The WWE is the latest American sports organization to face a lawsuit over head injuries, following the National Football League and the National Hockey League. More than 50 wrestlers are listed on the complaint. That includes Joseph Laurinaitis, Jimmy Snuka and Paul Orndorff. Laurinaitis was known as “Road Warrior Animal,” Snuka was “Superfly” and Orndorff was “Mr. Wonderful.” The lawsuit charges WWE with classifying the wrestlers as independent contractors instead of employees. This, the suit says, was to avoid paying injured wrestlers who could not work.
