Fifteen NFL players, including former Miami Dolphins quarterback and Hall of Famer Dan Marino, are filing a federal lawsuit against the league over concussions.

The players allege, among other things, that the league concealed the risk of concussions to players.

The newest group of plaintiffs, which includes Marino, joins more than 4,800 others who say that the NFL misled players about the long-term effects of concussions.  The National Football League has denied those allegations.

Marino, who was with the Miami Dolphins for seventeen seasons, went on to become a sports analyst for CBS Sports.  He was fired in February after being with the network for about ten years.  By recently adding his name to the roster of plaintiffs, many believe that Marino has elevated the cause.

One proposed settlement suggests that the NFL set aside a $675 million fund payable to those with qualifying diagnoses.
