As the NCAA moves toward a $2.8 billion settlement that could resolve three antitrust lawsuits — with the Big Ten the latest conference to give its approval — it is uncertain whether a fourth case will also be part of the agreement.

They said they won’t know whether their claims would be covered by the settlement until they have all the details of the proposal.
