Two people who have been briefed on the Big 12s decision tell The Associated Press that the conference is not planning on expansion.
The officials spoke to the AP on condition of anonymity because the conference had planned an announcement later Monday and had asked the schools involved not to speak publicly.
The decision came down after a six-hour meeting with university presidents and Commissioner Bob Bowlsby. A news conference is still planned for 5:30 p.m. with Bowlsby and Oklahoma President David Boren.
Bowlsby called the schools hoping to be added to the Big 12 to inform them of the boards decision.
