One of the greatest Washington Redskins of all-time is suing the NFL over lingering symptoms from concussions, The Washington Post reported.
Art Monk is the lead plaintiff, and he and 62 other former players are also going after Riddell -- the helmet company.
The players claim that the league did not institute policies to protect players from concussions. The suit says players who suffered head injuries were told by the NFL and its agents not to be overly concerned and were returned to game action minutes after the injuries.
The lawsuit claims that in 2007, NFL Commissioner Roger Goodell admitted publically that the league had been studying the effect of traumatic brain injury for close to 14 years. But it wasn't until June 2010 that the league acknowledged that concussions can lead to dementia, memory loss and related symptoms.
