Oregon, Ohio State, Texas and Penn State held on to their spots atop the Associated Press Top 25 college football poll, issued Sunday, but the same can’t be said for the rest of the teams after a day of upsets on Saturday.

The Ducks (11-0) were idle but remain the unanimous No. 1 team ahead of the three 10-1 squads. Among them, Ohio State posted the biggest win, sending previously undefeated Indiana (10-1) plummeting five spots to No. 10 after its 38-15 triumph.

But the Hoosiers weren’t the only team in a freefall.

Alabama (8-3) dropped six places to No. 13, and Ole Miss (8-3) also fell six rungs to No. 15 after losses to unranked Oklahoma and Florida, respectively. No. 19 BYU (9-2) and No. 20 Texas A&M (8-3) found themselves seven spots lower following defeats.

And Colorado (8-3) and Army (9-1) — teams that had College Football Playoff aspirations — both plunged seven places.

The topsy-turvy day also saw the Top 10 reorganized, with Notre Dame (10-1) moving up one place to No. 5, followed by Georgia (9-2) and Tennessee (9-2).

No. 8 Miami (10-1) and No. 9 SMU (10-1) each entered the Top 10, followed by Indiana.

Missouri (8-3) moved back into the Top 25, following its 39-20 win over Mississippi State. Washington State (8-3) fell out of the Top 25 after its 41-39 loss at Oregon State.

The CFP selection committee will announce its rankings, which ultimately will be used to determine the postseason field, on Tuesday.

11. Boise State (10-1)

12. Clemson (9-2)

13. Alabama (8-3)

14. Arizona State (9-2)
