Five former Kansas City Chiefs players are suing the franchise in an effort to learn what the team knew - and when - about concussions, according to the Kansas City Star.
Kevin Porter, Joe Phillips, Louis Cooper, Chris Martin and Leonard Griffin are suing for damages related to brain injuries suffered during their careers. They are seeking undisclosed financial damages.
The lawsuit is the first known to have been filed against an individual team. The National Football League recently settled the "Concussion Case" for $765 million with former players, without admitting guilt or being ordered to reveal a timeline of the league's knowledge about brain injuries.
