About 600 former National Football League players are suing the league, accusing it of putting profit before their health.
They allege the NFL gave them powerful painkillers to keep them playing through injuries, but left them with major health problems after they retired.
Among the plaintiffs is former Chicago Bears quarterback Jim McMahon, who says he became dependant on painkillers. McMahon is now battling dementia.
There's no comment on the suit yet from N-F-L commissioner Roger Goodell.
In 2013, the NFL settled a case that accused it of keeping players in the dark about the effects of concussions.
The league settled that lawsuit for $765-million without admitting wrongdoing.
