The Mountain West and Pac-12 conferences were unable to reach an agreement to extend their football programs beyond the 2024 season before Sunday’s deadline, sources confirmed to ESPN.

While a return is theoretically possible, the most likely scenario is that Oregon State and Washington State create completely independent schedules for the 2025 season.

“The gap (between the parties) is too wide,” a source told ESPN.

The main reason no agreement was reached is that the Pac-12 wants to be flexible in responding to further fundamental changes in college sports next year. Financial factors also played a role, sources told ESPN.

According to sources, there have been no substantive discussions about Oregon or Washington joining any of the remaining four energy conferences.

This year, all 12 Mountain West schools will play seven conference games, plus either OSU or WSU under an agreement reached in December after the Pac-12 broke apart and was left with only two members. As part of that deal, the Pac-12 paid the MWC about $14 million.

OSU and WSU will compete in most of their remaining sports, including basketball, as associate members of the West Coast Conference for the next two years.

The failure of the conferences to reach an agreement was first reported in the San Jose Mercury News.
