Seventy-five former players are suing the NFL, claiming the league intentionally withheld knowledge of the damaging effects of concussions for 90 years, TMZ.com reported Tuesday. According to TMZ.com, the plaintiffs claim that "The NFL knew as early as the 1920's of the harmful effects on a player's brain of concussions; however, until June of 2010 they concealed these facts from coaches, trainers, players and the public." The website says the group includes former Pro Bowlers Mark Duper of the Miami Dolphins and Rodney Hampton of the New York Giants. Former Super Bowl MVP Ottis Anderson is also named in the lawsuit, TMZ.com reported. The suit alleges that the NFL did not admit that multiple concussions can affect memory and cause dementia and chronic traumatic encephalopathy (CTE) until 2010, according to TMZ.com. League spokesman Greg Aiello issued a statement Tuesday saying the NFL has not "seen the complaint but would vigorously contest any claims of this kind."
