MINNEAPOLIS (AP) -- Three former college football players have filed a federal lawsuit in Minnesota alleging that NCAA did not inform former players about the risks of concussions inherent in the sport.

The lawsuit filed Tuesday also says the NCAA failed in its duty to establish protocols to prevent, monitor and treat brain injuries. Former University of Minnesota linebacker Joey Balthazor and former Vanderbilt players Paul Morgan and Cliff Deese are named as plaintiffs.

The suit seeks medical monitoring and testing for former players who are suffering from head injuries related to their playing days. The suit seeks class-action status, but is limited to players who did not play in the NFL.

Similar suits have been filed elsewhere around the country.
