The two biggest brands representing the Big 12 are walking out the door. A formal announcement from both Oklahoma and Texas was sent to the conference on Monday morning.

“The University of Texas at Austin and The University of Oklahoma notified the Big 12 Athletic Conference today that they will not be renewing their grants of media rights following expiration in 2025,” the statement said. “Providing notice to the Big 12 at this point is important in advance of the expiration of the conference’s current media rights agreement. The universities intend to honor their existing grant of rights agreements. However, both universities will continue to monitor the rapidly evolving collegiate athletics landscape as they consider how best to position their athletics programs for the future.”

There was no mention of the SEC in the statement. It was reported last week that both schools were seriously considering a move to the league.

Sunday night, Big 12 commissioner Bob Bowlsby released a statement saying that presidents from Texas and Oklahoma both met with the conference’s executive committee about staying in the league. Bowlsby thought those talks went well.

“The meeting was cordial, and the Executive Committee expressed a willingness to discuss proposals that would strengthen the Conference and be mutually beneficial to OU and UT, as well as the other member institutions of the Conference,’ Bowlsby said. ‘I expect that we will continue our conversations in the days ahead and we look forward to discussing thoughts, ideas and concepts that may be of shared interest and impact.”

News of the change will undoubtedly result in a domino effect that will spread across college athletics and could seriously alter multiple conferences.

What’s the next move? Stay tuned.
