Former Packers running back Paul Hornung has filed a lawsuit against Riddell, a company that makes football helmets.
In the lawsuit, which obtained by the New York Times, the Hall of Famer alleges that Riddell led players to believe that the company's plastic helmets would provide protection against brain trauma.
"Prior to, during and after Paul Hornung's NFL football career, Riddell knew of the harmful long-term effects of brain traumas sustained by football players while wearing Riddell's supposed protective equipment; however, it misrepresented and concealed these facts from Paul Hornung," the lawsuit states.
