Georgia was the new No. 1 in the College Football Playoff rankings Tuesday night, followed by Ohio State, Michigan and TCU.
The Bulldogs' rise from No. 3 was no surprise after their dominant victory against previously top-ranked Tennessee on Saturday.
Clemson, which was No. 4 in the selection committee's first rankings last week, also lost, clearing way for changes in the top four.
Ohio State stayed at two. The Buckeyes' Big Ten rival, Michigan moved up from five to three. TCU jumped three spots to No. 4, putting the nation's four unbeaten teams at the top of the rankings.
Tennessee fell to No. 5 and was followed by Oregon from the Pac-12 and LSU, which jumped three spots to seventh after the Tigers knocked off Alabama.
Clemson fell to 10th and Alabama dropped from sixth to ninth after its second loss of the season.
This is the first time since the College Football Playoff rankings began in 2014 that neither Clemson nor Alabama have been ranked in the top six.
There has never been a College Football Playoff without the Tigers and the Crimson Tide, which have combined to win five of the eight CFP championships.
