South Carolina 14

COLUMBIA, S.C. -- Tim Tebow tied the SEC touchdown record and No. 1 Florida gained its first perfect league season in 13 years with a victory over South Carolina.

The Gators (10-0, 8-0) remained on track for a third national title in four years. They again called on their SEC-leading defense to save things against former coach Steve Spurrier.

Down 17-14, South Carolina (6-5, 3-5) drove 48 yards to the Florida 22. But defensive lineman Justin Trattou intercepted Stephen Garcia and brought it back 53 yards. Tebow cashed in the touchdown four plays later, a 1-yard burst that was the 53rd of his SEC career to match LSU great Kevin Faulk.

Florida hadn`t gone undefeated in the SEC regular season since Spurrier`s 1996 national champions.

Alabama 31, Miss. St. 3

STARKVILLE, Miss. -- Mark Ingram rushed for 149 yards and two touchdowns, Greg McElroy threw two long scoring passes and No. 3 Alabama improved to 10-0 for the second straight year.

TCU 55, Utah 28

FORT WORTH, Texas -- In likely its last significant hurdle to an undefeated regular season, No. 4 TCU scored three touchdowns in a 2½-minute span early in the second quarter and beat No. 16 Utah.

The Horned Frogs (10-0, 6-0 Mountain West) stretched their winning streak to 12 games since a last-minute loss last November at Utah (8-2, 5-1), which had won 22 of 23. TCU also has won 13 in a row at home since losing when the Utes last visited two years ago.

Boise St. 63, Idaho 25

BOISE, Idaho -- Kellen Moore threw four touchdown passes to Austin Pettis and tied a career high with five overall, leading No. 6 Boise State to the victory.

Ga. Tech 49, Duke 10

DURHAM, N.C. -- Jonathan Dwyer rushed for 110 yards and two touchdowns, Josh Nesbitt accounted for three scores and No. 7 Georgia Tech clinched a spot in the ACC championship game.

Pitt 27, Notre Dame 22

PITTSBURGH -- Jonathan Baldwin made two exceptional catches that allowed No. 8 Pittsburgh to open up an 18-point lead in the fourth quarter, and the Panthers held on for a victory that might raise more cries for Fighting Irish coach Charlie Weis` ouster.

LSU 24, La. Tech 16

BATON ROUGE, La. -- Keiland Williams ran for 116 yards and two second-half touchdowns, helping No. 9 LSU fend off upset-minded Louisiana Tech.

Ohio St. 27, Iowa 24

COLUMBUS, Ohio -- Backup Devin Barclay kicked a 39-yard field goal in overtime to send No. 10 Ohio State to the Rose Bowl for the first time in 13 years.

The Buckeyes (9-2, 6-1) clinched at least a share of their fifth consecutive Big Ten title and the conference`s automatic BCS bid.

Stanford 55, USC 21

LOS ANGELES -- Toby Gerhart rushed for 178 yards and three touchdowns and No. 25 Stanford emphatically followed up its 2007 upset at the Coliseum with the most points ever allowed by the No. 11 Trojans.

The loss was the Trojans` worst since a 51-0 defeat at home against Notre Dame in 1966 and essentially ended USC`s seven-year run as Pac-10 champions.

North Carolina 33,

Miami 24

CHAPEL HILL, N.C. -- Kendric Burney returned one of his three interceptions for a 77-yard touchdown and his third pick resulted in a bizarre fourth-quarter score that helped North Carolina get the win over No. 12 Miami.

UCF 37, Houston 32

ORLANDO, Fla. -- Central Florida slowed down Case Keenum and stopped the nation`s most prolific passer from pulling off another improbable comeback for No. 13 Houston.

Cal 24, Arizona 16

BERKELEY, Calif. -- Shane Vereen scored on a 61-yard run after an odd penalty thwarted a potential go-ahead drive for No. 18 Arizona and California went on to a victory.

Penn St. 31, Indiana 20

STATE COLLEGE, Pa. -- Linebacker Navorro Bowman had a 73-yard interception return for a touchdown and Evan Royster scored twice to help No. 19 Penn State overcome four first-half turnovers.
