It’s been reported and assumed that the three teams leaving the AAC for the Big 12 (Cincinnati, Houston, and UCF) would do so before the 2023 academic year. It’s also been reported and assumed that the six C-USA teams replacing them (FAU, UAB, Charlotte, Rice, North Texas, and UTSA) would do so at the same time, to prevent the AAC from dropping to just eight teams. However, no official announcements had been made.
Now, everything is official.
The three AAC schools, plus BYU, will join the Big 12 on July 1, 2023. Immediately following this announcement, it was also announced that the six C-USA schools will be entering the AAC on the same day.
