  In July 2021, after 25 seasons as members of the Big 12, Texas and rival Oklahoma accepted invitations to join
  the Southeastern Conference (SEC) no later than the 2025 season. In February 2023, the Big 12 announced that the
  two schools had negotiated a combined $100 million early termination fee in order to leave for the SEC a year
  before the schools' media rights deal with the Big 12 was set to expire. The Longhorns football team will
  continue competing in the Big 12 through the 2023 season before moving to the SEC in 2024.
