USA Today, citing documents it had obtained, reported that the suit cites "carelessness, negligence, intentional misconduct" regarding concussions.
By filing the lawsuit, Marino joined approximately 4,500 former players who have sued the league over concussions.
The league agreed to a $765 million settlement last August that was rejected by Federal Judge Anita B. Brody in January. Brody said the money might not be enough to cover claims over the life of the 65-year agreement.
The 52-year Marino reportedly did not reveal any symptoms he may have.
He is, according to the Times, one of at least 41 Hall of Fame players to have sued the league over concussions.
In an LA state of mind
Want to attend a Rangers-Kings Stanley Cup finals game?
If you live in New York, or any other East Coast town, you'd be better off - financially speaking - traveling to Los Angeles.
TiqIQ.com notes that the average ticket price for each of three Rangers home games - assuming the series goes at least six games - is $2,424.64. By contrast, the average price for the four games at the Staples Center in LA - assuming a seven-game series - is $1,506.06.
That means that, on average, a New Yawker could fly to LA, have a 2-day hotel stay and see a game for less than it would cost to go to Madison Square Garden.
