To do the latter, Big 12 bylaws require a majority vote of the league's board of directors.
"It's going to take major, major reforms," the source told the Oklahoman. "We'd have to have an interim commissioner."
Big 12 members were angered by the network's agreement with Fox Sports to move a conference game to the Longhorn Network and its decision to show high school highlights after the Big 12 voted to keep televised high school games off school-branded networks.
The source told the Oklahoman that a move by Oklahoma and Oklahoma State to the Pac-12 wasn't inevitable.
The University of Oklahoma's board of regents and its counterpart at Texas granted their school presidents Monday the authority to take action regarding conference realignment.
The moves clear the way for the Sooners and Longhorns to apply formally to the Pac-12, with whom they have been undergoing discussions in recent days on how to make the schools' addition to the conference work.
After the regents meeting had adjourned, Boren admitted he's had "very warm and constructive discussions" with Pac-12 officials, but wouldn't say when the Sooners might apply for conference membership.
