There have been plenty of college football rivalries throughout the years: Army-Navy, the Iron Bowl, and the Red River Rivalry, just to name a few.
However, one of the most historic and exciting rivalries will be coming to a close, for now, with the recent decision by Notre Dame.
Michigan announced Tuesday that Notre Dame has cancelled three games from 2015-2017 between the two schools.
The Wolverines and Irish have met on the football field 40 times, with Michigan holding a 23-16-1 all-time record against the Fightin' Irish.
This cancellation is a result of Notre Dame's move to the ACC.
While the football program will remain independent, the Irish still have to play at least five ACC teams per season, making it impossible for ND to keep all their rivalries.
With that being said, there have been a laundry list of classic rivalries put on hold for various reasons, including conference expansion.
Let's take a look at the best rivalries other than Notre Dame-Michigan that have been put on hiatus or ended.
