In another sign of a precarious era of realignment in college sports, the Big 12 Conference moved Friday to add Brigham Young University, Cincinnati, Houston and the University of Central Florida, with the colleges able to join as early as 2023.

B.Y.U. will join the Big 12 on July 1, 2023, while the other three programs will join the league no later than July 1, 2024, Big 12 Commissioner Bob Bowlsby told reporters on Friday.
