Ohio State was No. 5 on 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. That game was 24-20 heading into the fourth quarter and 31-23 with 7:23 to go before Michigan blew it open.

"It was talked about in the committee room that going into, really early in the fourth quarter, the game was still close," said selection committee chairman Boo Corrigan, who is North Carolina State's athletic director. "That being said, you can't completely dismiss the way the fourth quarter ended with Michigan kind of taking over the game there late."

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.

The final rankings and the four-team field for the College Football Playoff will be set Sunday. The semifinals will be played Dec. 31 in the Peach Bowl in Atlanta and the Fiesta Bowl in Glendale, Arizona.

The top four 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), which fell nine spots to 14th, 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.
