Notre Dame is fourth and Oklahoma is fifth.
The unbeaten Hawkeyes (11-0) have their best ranking since being No. 3 in 2002. They have clinched the Big Ten West and a spot in the conference title on Dec. 5.
Michigan State jumped three spots to No. 6 after upsetting Ohio State 17-14 on Saturday. The Buckeyes, who began the season as a unanimous No. 1 and slipped to No. 2 earlier this month, fell to eighth.

The Tigers have lost three straight since topping out at No. 4 on Oct. 31.
The Utes were No. 3 midway through October, but are 2-3 since. Utah lost to UCLA on Saturday after falling in overtime last week to Arizona.

All four teams that moved into the rankings this week have already been there previously this season.

RANKED vs. RANKED
No. 7 Baylor at No. 15 TCU, Friday. Big 12 championship and playoff implications, and a possible matchup of third-string quarterbacks.
No. 4 Notre Dame at No. 13 Stanford. Elimination game between playoff hopefuls.
No. 5 Oklahoma at No. 9 Oklahoma State. The Sooners can clinch the Big 12 title with a victory, but will they have to play without quarterback Baker Mayfield?
No. 8 Ohio State at No. 12 Michigan. The first meeting of Urban Meyer and Jim Harbaugh has lost some of its juice.
No. 14 Florida State at No. 10 Florida. The Gators have their spot in the SEC title game locked up, but are dragging into their rivalry game off an overtime win against FAU.
No. 16 Navy at No. 21 Houston. The winner gets the West division title, spot in the American championship game and inside track to New Year's Six bowl.
No. 19 Mississippi at No. 23 Mississippi State. The Rebels can still win the SEC West with a victory and Alabama loss to Auburn.
