The college football regular season is in the books and rivalry week did not disappoint.

Week 13 delivered plenty of contentious and bitter moments, and it got started early in the day with "The Game." No. 3 Michigan held on to beat No. 2 Ohio State in a Big Ten thriller to advance to the conference title game.

Not to be outdone, the Iron Bowl played out in typical Iron Bowl fashion — absolutely off-the-wall action throughout a game that culminated in a late heave to the end zone on a fourth-and-31. This time, it was Alabama that came out with the dramatic 27-24 victory over its rivals from Auburn.

Later on, Washington survived a scare in the latest rendition of the Apple Cup. The Huskies had a clutch fourth-down conversion in their own territory with just over a minute left and drove the length of the field to beat Washington State with a last-second field goal.

There was spitting. There was fighting. It got plenty ugly in the last week of the regular season.
