Former pro football player Paul Hornung recently sued Riddell Sports, the manufacturer of the helmets he used during his years in the game. Hornung claims Riddell’s helmets did nothing to protect him from brain injury. Riddell was the NFL’s helmet maker from 1989 to 2014. Hornung, 80, won the Heisman Trophy at Notre Dame in 1956, was named MVP while playing in the National Football League for the Green Bay Packers, and was inducted into the Pro Football Hall of Fame in 1986. He says in his lawsuit that he suffered concussions and subconcussive brain traumas while wearing Riddell's helmets. He further alleges that these helmets provided no protection from brain injuries. Yet, players "were led to believe that the innovative helmets would do so," Hornung adds. Hornung, like many other players, has been diagnosed with dementia and, according to his lawyer, "it's suspected that his brain has the telltale signs of Chronic Traumatic Encephalopathy (CTE)." CTE cannot be diagnosed until after death. Hornung is, according to his lawyer, showing symptoms of the neurodegenerative disease.
