Clemson did enough to stay undefeated with a 21-20 victory over North Carolina on Saturday, but not enough to maintain its No. 1 ranking.
Alabama is the new No. 1 in the latest AP top 25 poll, which was released Sunday afternoon.
The Tigers dropped to No. 2, with Georgia No. 3, Ohio State No. 4 and LSU rounding out the top five.
The rest of the top 10 includes Oklahoma at No. 6, followed by Auburn, Wisconsin, Notre Dame and Florida.
