Marcus Randall may have saved LSU's season.

Randall came off the bench and threw two touchdown passes, including a 10-yarder with 27 seconds to play, to help No. 24 LSU upset No. 12 Florida, 24-21, last night in Gainesville, Fla.

The Tigers, the defending Bowl Championship Series national champions, already have been eliminated from the national title picture. But they still could repeat as Southeastern Conference champs. They certainly showed anything is possible against the Gators.

Not only did LSU (4-2, 2-2) rebound from an embarrassing 45-16 loss at Georgia last week, it also overcame a 21-7 deficit, three turnovers and the loss of starting quarterback JaMarcus Russell.

"We had to get humiliated," LSU Coach Nick Saban said. "Sometimes, especially with young players -- just like your puppy dog -- you have to rub their nose in it. We got our nose rubbed in it, and we responded the right way and I'm really proud of that."

The Gators (3-2, 2-2) led 21-17 with 2 minutes 6 seconds left, and the Tigers needed to go 50 yards for the go-ahead score.

No problem. Not on a night when the Tigers moved the ball at will against Florida, outgaining the Gators 464-236 in total yards.

"We were in position to finish the game and we didn't get it done," said Florida Coach Ron Zook, who fell to 19-12 in three seasons since replacing Steve Spurrier. He now has more home losses (six) than Spurrier had in The Swamp (five) in 12 seasons.

Joseph Addai ran three times for 34 yards on the drive, but Randall made the biggest play. He avoided a heavy rush and found Addai for a 10-yard touchdown pass on third down with 27 seconds remaining.

* AUBURN 52, LOUISIANA TECH 7: Jason Campbell passed for 201 yards and two touchdowns, including a school-record 87-yarder to Silas Daniels, leading the No. 6 Tigers past the Bulldogs in Auburn, Ala.

Auburn is 6-0 for the first time since the 1997 season, with only one game decided by less than 24 points.

The Tigers have allowed one touchdown or fewer in all but one game and still haven't given up a rushing touchdown. They collected nine sacks and forced three turnovers.

Auburn outgained Louisiana Tech 472-222. The Bulldogs pushed into Auburn territory five times in the first half, but couldn't get points against the nation's No. 4 scoring defense.

The Tigers broke Alabama's 17-year-old record of 199 consecutive made extra points after their first touchdown.

* WISCONSIN 24, OHIO STATE 13: The 15th-ranked Badgers throttled the No. 18 Buckeyes' offense, and Anthony Davis slashed for 168 yards and a touchdown in Columbus, Ohio.

It was Wisconsin's third straight win on Ohio State's home turf, the first time a visitor has done that since Illinois won four in a row from 1988 to '94. The Badgers had never before won even twice in a row at Ohio State in the series dating from 1913.

The loss ended Ohio State's 18-game home winning streak and, on the heels of last week's stunning 33-27 overtime loss to Northwestern, pinned Coach Jim Tressel with back-to-back losses for the first time in his 31/2 seasons. The Buckeyes (3-2) also dropped to 0-2 in the Big Ten for the first time since 1992.

Wisconsin, 3-0 in the Big Ten, is 6-0 for the first time since 1998. In 1998, the Badgers went on to go 11-1, share the Big Ten title and win the Rose Bowl.

Sophomore John Stocco was steady all day for the Badgers, completing 15 of 24 passes for 169 yards and two touchdowns without an interception.

Ohio State's own first-year starter at quarterback, sophomore Justin Zwick, and his ineffective offense were booed loudly by 105,090 partisan fans, the fifth-largest crowd in Ohio Stadium history. Zwick completed 15 of 31 passes for 125 yards -- with two of the completions and 27 of the yards coming in the final seconds.

Trailing 14-13 at the half, the Buckeyes mustered just two first downs in the second half against a Wisconsin defense that came into the game leading the nation in scoring defense (5.2 points per game) and yards allowed (193.2). Ohio State ran 22 plays in the second half for 49 yards.

Shortly after the game ended, several players exchanged punches at midfield while coaches and police tried to pull them apart. The melee lasted for less than a minute, but was representative of the bad blood between the teams in recent years.

* MISSISSIPPI 31, SOUTH CAROLINA 28: In a season where two-quarterback rotations are in vogue, Rebels Coach David Cutcliffe went one better, shuttling three signal-callers in and out in Columbia, S.C.

Ethan Flatt became the hero, finding Bill Flowers in the corner of the end zone for a 29-yard touchdown pass on fourth down with 1:05 left.

Cutcliffe rotated his quarterbacks on a play-by-play basis. Flatt often came in on passing downs and finished 18 of 27 for 214 yards. The other two quarterbacks mainly ran the ball, with Spurlock gaining 34 yards on eight carries and Robert Lane running for 16 yards on four carries.

The quarterback platoon stumped the No. 25 Gamecocks (4-2, 2-2 SEC) early as the Rebels quickly took a 14-0 lead late in the first quarter and led 21-14 at half.

The Gamecocks' defense -- first in the SEC in rushing defense and third against the pass -- gave up 319 yards in the first half. South Carolina came in allowing 256 yards a game.

The defense stiffened in the second half, holding Ole Miss (3-3, 2-1) to 95 yards. But most of those came on the winning drive. The loss ruined an excellent performance by Syvelle Newton, who was starting his first SEC game. Newton was 12 of 27 for 291 yards and a touchdown. He also led the Gamecocks in rushing, gaining 65 yards.

* PURDUE 20, PENN STATE 13: Taylor Stubblefield caught a 40-yard touchdown pass and became the Big Ten's career receptions leader as the No. 9 Boilermakers held on to beat the Nittany Lions in State College, Pa.

Stubblefield's 40-yard sprint down the left sideline on the first possession of the second half put the Boilermakers (5-0, 2-0) up 17-10. After that, it was all Purdue could do to hold on to the lead.

Penn State (2-4, 0-3) had a second and one on the Purdue 7, but had to settle for a 27-yard field goal that made it 17-13.

Purdue's next possession ended when Calvin Lowry intercepted Kyle Orton's pass, Orton's first interception and Purdue's first turnover of the season. That left Hawaii as the only NCAA Division I-A team without a turnover.

Orton completed 24 of 35 for 275 yards, with two interceptions and one touchdown. He was sacked three times, as many times as he'd been sacked all year.

* OKLAHOMA STATE 42, COLORADO 14: Vernand Morency's hard-nosed running led to two touchdowns and cleared the way for Donovan Woods to throw for three more scores, lifting the No. 22 Cowboys to a victory in Boulder, Colo.

Oklahoma State (5-0, 2-0 Big 12) established its powerful running game early, blowing the Buffaloes back on Morency's 58-yard touchdown run on its third play. Morency added a six-yard touchdown run in the second quarter and finished with 165 yards, his seventh straight regular season game with at least 100 yards.

Lawrence Vickers had 168 total yards -- 72 rushing, 96 receiving -- and scored on a six-yard touchdown run early in the fourth quarter for Colorado. The Buffaloes (3-2, 0-2) finished with 445 total yards. Colorado is 0-2 in conference for just the seventh time since 1948.

* FLORIDA STATE 17, SYRACUSE 13: Leon Washington rushed for a career-high 164 yards and scored on runs of 21 and 45 yards, as the No. 8 Seminoles survived a major scare in Syracuse, N.Y.

It was the third game against a ranked team for Syracuse (3-3), and unlike the previous two -- a 51-0 loss at No. 9 Purdue and a 31-10 loss at No. 10 Virginia -- the Orange made it difficult for the Seminoles (4-1) and quarterback Wyatt Sexton, who was making his first road start.

LSU's Joseph Addai holds onto the go-ahead touchdown pass, fending off Florida's Cornelius Ingram in the Tigers' upset at The Swamp.
