Ohio State was No. 5 Tuesday night in the second-to-last College Football Playoff rankings, positioned to possibly take advantage if one of the top four slips up on championship weekend.
Georgia (12-0) was No. 1 again. No. 2 Michigan (12-0) and No. 3 TCU (12-0) both moved up a spot and Southern California (11-1) climbed two spots into the fourth slot.
The Buckeyes (11-1) dropped three spots after losing 45-23 to the rival Wolverines on Saturday at home.
Alabama (10-2) moved up a spot to No. 6 and was followed by Southeastern Conference rival Tennessee, which beat the Crimson Tide in October.
All play in their conference championships game this weekend. The undefeated teams might not need to win this weekend to lock up a spot.
Georgia plays LSU (9-3) in the SEC title game. Michigan plays Purdue (8-4) for the Big Ten championship. TCU faces Kansas State, which is 10th in the latest rankings and has already lost to the surprising Horned Frogs.
USC and Heisman Trophy frontrunner Caleb Williams face Utah, No. 11 in the rankings, on Friday night in Las Vegas for the Pac-12 championship.
If the Trojans slip up, that could give Ohio State a second chance.
