Oregon claimed the No. 2 spot in the AP Top 25 college football rankings, marking the top of the poll with the first of several shakeups.

Miami, which had a bye, slipped one spot to No. 3 and was followed by top-five newcomers No. 4 Mississippi and No. 5 Oklahoma. That's a nine-rung promotion for Ole Miss, which beat LSU Saturday, giving the Rebels their highest ranking since 2015.

Ohio State remained No. 1 for the fifth straight week, but the margin of first-place votes between the top two teams is the closest of the regular season.

Iowa State beat Arizona, 39-14, reaching 5-0 for the second consecutive season. The Cyclones remained at 14th in the new poll.
