The 2023 Big 12 football schedule, released on Tuesday, will make for some awkward get-togethers.

While BYU, Cincinnati, Houston and UCF are joining the league, Oklahoma and Texas have not yet departed for the SEC.

All 14 teams will play nine conference games, starting Sept. 16 when newcomer Houston hosts TCU, the 2022 College Football Playoff runner-up and a former Southwest Conference rival.

Texas will face just two of the Big 12's newest entries, and the games will come back-to-back. The Longhorns will visit Houston Oct. 21 and host BYU Oct. 28

Oklahoma, meanwhile, will open its Big 12 schedule by visiting Cincinnati Sept. 23. The Sooners will later host UCF Oct. 21 and travel to BYU Nov. 18.

The annual Red River Rivalry between Texas and Oklahoma is set for Oct. 7 at the Cotton Bowl in Dallas.

A rematch of last season's Big 12 championship game, between TCU and equally surprising Kansas State, will be Oct. 21 in Manhattan, Kan.

Oklahoma State is slated to host Oklahoma on Nov. 4 in the Bedlam series matchup.

Oklahoma and Texas will join the SEC in either 2024 or 2025. The two bluebloods' decision to jump ship prompted the Big 12 to invite BYU, Cincinnati, Houston and UCF, some of the most successful athletic programs from outside the power conferences.
