Former players file explosive concussion lawsuit against NFL

Former Miami Dolphins wide receiver Mark Duper and former New York Giants running backs Otis Anderson and Rodney Hampton were among the litigants in the potentially explosive suit.

TMZ was the first to obtain a copy of the lawsuit. It writes:

The suit claims the NFL commissioned a study in 1994, titled "NFL Committee on MIld Traumatic Brain Injury" and published a report in 2004, concluding there was "no evidence of worsening injury or chronic cumulative effects" from multiple concussions.

And, the suit alleges, it was not until June, 2010, that the NFL acknowledged concussions can lead to dementia, memory loss, CTE and related symptoms. All of the players are claiming they suffered injuries as a result of multiple concussions.
