CHICAGO (AP) — The NCAA is now facing 43 class-action lawsuits related to the handling of concussions by Division One football programs after 18 more were filed this week.

The complaints also name college conferences and in some cases schools. The Chicago-based law firm Edelson PC has been filing the lawsuits in batches since May.

The latest were filed Tuesday on behalf of former players from Texas A&M, UCLA, Maryland, Richmond, Idaho, South Carolina, Mississippi, Syracuse, Pittsburgh, Georgia Tech, Notre Dame, Alabama and Iowa.

On Monday, former players from Memphis, Ball State, Rutgers, Eastern Michigan and Florida A&M filed lawsuits.

The players are seeking damages for injuries they claim are the result of mishandled concussions they suffered while playing college football.

A judge in a previous case ruled one large class-action concussion lawsuit could not be filed against the NCAA.
