Former Miami Dolphins Quarterback Dan Marino is among the latest group of ex-professional football players to file a lawsuit against the NFL.
The lawsuit is yet another concussion related issue surrounding the NFL with Marino just one of 15 former players who filed the action in federal court last week.
However the lawsuit doesn't specify any medical problems suffered by Marino or his compatriots but seeks unspecified damages and medical monitoring.
The 15 former players now join over 4,800 other players who claim that the NFL misled them about the long term dangers of concussions, a claim the league have denied.

Marino retired in 1999 after playing in 242 games for the Miami Dolphins and assembling a career total of 420 passing touchdowns.
