PHILADELPHIA (AP) -- Seven former players have sued the NFL in Philadelphia over concussion-related injuries, the first potential class-action lawsuit of its kind.
The players accuse the league of failing to protect their health and of trying to conceal any links between football and brain injuries.
The players include former Philadelphia Eagles quarterback and two-time Super Bowl champion Jim McMahon.
The suit accuses the NFL of negligence and intentional misconduct in its response to the headaches, dizziness and dementia that former players have reported.
The suit, filed Wednesday, seeks medical monitoring along with funds to pay for the care of injured players.
NFL spokesman Brian McCarthy says the league will vigorously contest the claims.
Lawyer Larry Coben of Philadelphia says one client may lose his home because of his health-related problems.
