Ohio State, Miami and Clemson plunged in The Associated Press Top 25 college football poll Sunday following their losses during a wild weekend, while eight of the top 10 teams moved up one spot behind No. 1 Oregon.
The Ducks occupied the top spot for the seventh straight week.
The shakeup creates two top-five matchups in conference championship games coming up on Saturday -- a day before the College Football Playoff bracket is announced. Oregon, the nation's only unbeaten team, will face No. 3 Penn State in the Big Ten game in Indianapolis.
