No. 1 Oregon and No. 2 Auburn held their places, though the Ducks' narrow escape in a 15-13 victory Saturday night at California cost them 11 first-place votes and left them with 38.
Auburn, which erased an early 14-point deficit and beat Georgia 49-31, picked up 10 first-place votes for a total of 12.
The big move came at Nos. 3 and 4.
TCU moved ahead of Boise State last week after a 47-7 victory against previously unbeaten Utah. But that win didn't look quite so impressive after the Utes were beaten 28-3 at Notre Dame on Saturday. The loss by Utah combined with TCU's 40-35 victory against San Diego State and Boise State's 52-14 win at Idaho on Friday night caused a 41-point swing.
The Horned Frogs led the Broncos by 25 points last week. This week they trail by 16.
Boise State picked up two more first-place votes this week to give it nine. TCU lost a first-place vote but still has one.
The rest of the top 10 was nearly unchanged with No. 5 LSU followed by Wisconsin, Stanford, Ohio State and Nebraska. Alabama jumped one spot to No. 10, while Michigan State slipped a spot to No. 11 after a week off.
Dropping out of the rankings were Central Florida, which lost its first game as a ranked team 31-21 to Southern Mississippi, and Florida, which lost 36-14 to South Carolina.
No. 20 Southern California and No. 24 Miami both moved back into the poll for the third time this season.
Oklahoma State was No. 12, followed by Arkansas, Virginia Tech and Missouri, while Oklahoma, South Carolina, Texas A&M, Nevada and USC round out the top 20.
The final five began with Iowa, which slipped eight spots to No. 21 after losing to Northwestern, Mississippi State, which dropped five after losing at Alabama, and Arizona, which also dropped five places after a loss to USC.
Then came the Hurricanes and Utah, which tumbled 10 spots after its second consecutive loss.
