Ohio State tumbled out of the top five after it lost at home to Michigan on Saturday.
The Buckeyes fell five spots to No. 7 after the 13-10 loss to their rivals. Oregon, the lone undefeated team in college football, stayed at No. 1 ahead of Texas, Penn State, Notre Dame and Georgia.
Texas beat Texas A&M in the first game between the two schools since 2011. Penn State will play Oregon for the Big Ten title after beating Maryland. Notre Dame beat USC to effectively clinch a spot in the College Football Playoff and Georgia needed eight overtimes to take down Georgia Tech 44-42 on Friday night.
Tennessee jumped ahead of Ohio State at No. 6 and the Buckeyes are followed by SMU, Indiana and Boise State to round out the top 10.
