The NCAA is now facing 43 class-action lawsuits related to the handling of concussions by Division I 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.
