No decision made on expansion

NEW YORK -- The NCAA's senior vice president says no decision has been made on whether to expand the men's basketball tournament.

Greg Shaheen reiterated Tuesday at CBS's NCAA tournament media day that the organization is doing its "due diligence." He says "nothing is a done deal or decided at this point in time."

The NCAA has been researching the issue and talking to its members for several months. The organization can opt out of the final three years of its 11-year, $6 billion contract with CBS after this season.

CBS Sports president Sean McManus says the network has a history of successfully renewing the rights to events it wants to keep.
