The agreement between the Pac-12 and Big Ten to play regularly scheduled games against each other league-wide is off, less than eight months after it was announced.

The reason: The Pac-12's nine-game inter-conference football schedule, which appears to be staying that way.

"We recently learned from Pac-12 Commissioner Larry Scott that the complications associated with coordinating a non-conference football schedule for 24 teams across two conferences proved to be too difficult," Big Ten commissioner Jim Delany said in a statement. "Those complications, among other things, included the Pac-12’s nine-game conference schedule and previous non-conference commitments."

In a statement, Pac-12 commissioner Larry Scott said "the Pac-12 came to the conclusion that it's in our best interests to maintain our nine-game conference schedule and maximum flexibility in out-of-conference scheduling."

In late December, the two leagues agreed to a scheduling agreement that would have began on the football field in 2017, with every team from the Pac-12 booked to play one Big Ten team, every year. The leagues agreed to increase the number of games between the two in all sports.

At the time, it was thought to be the leagues' declaration that expansion had stopped, a unifying measure between two of the BCS' four major power players and a solution for two conferences that each owned their own television networks.
