The Gamecocks moved up in the polls Sunday after their historic win Saturday over Florida.
South Carolina (7-3, 5-3 SEC) climbed five spots to No. 17 in both The Associated Press Top 25 and USA Today Coaches Poll.
On Saturday in The Swamp, Marcus Lattimore ran 40 times for a career-high 212 yards and three touchdowns, Stephen Garcia played turnover-free and the Gamecocks knocked off Florida to clinch the Southeastern Conference's Eastern Division.
The Gamecocks won for the second time in 19 tries against Florida, snapped an 0-for-12 streak in Gainesville and earned a spot in the league title game for the first time.
South Carolina will play second-ranked Auburn on Dec. 4, with the winner advancing to the Bowl Championship Series.
Before then, the Gamecocks have two more regular season games: the final home game this Saturday against Troy, and the annual rivalry game No. 27 at Clemson.
The Gators (6-4, 4-4) lost to a division opponent for the first time in 17 games, dropped their third consecutive home game and proved they didn't deserve to play for a championship. It's the program's first three-game losing streak at home since 1989.
Florida's return to the Top 25 lasted just one week.
In other Top 25 news, Boise State jumped back ahead of TCU in The Associated Press poll after the Horned Frogs played their closest game of the season.
No. 1 Oregon and No. 2 Auburn also held their places, though the Ducks' narrow escape in a 15-13 victory Saturday night at California cost them 11 first-place votes and left them with 38.
Auburn, which erased an early 14-point deficit and beat Georgia 49-31, picked up 10 first-place votes for a total of 12.
The big move came at Nos. 3 and 4.
TCU had moved ahead of Boise State last week after a 47-7 victory against previously unbeaten Utah. But that win didn't look quite so impressive after the Utes were beaten 28-3 at Notre Dame on Saturday. TCU also had to hold off San Diego State 40-35.
