No. 15 Texas A&M 29, No. 1 Alabama 24

No. 15 Texas A&M upset No. 1 Alabama 29-24 on Saturday taking one less unbeaten team out of the race for the BCS championship game.

Johnny Manziel and the Aggies shook up the national title race in Tuscaloosa, Ala., jumping out to a quick three-touchdown lead and then holding on at the end to Alabama's 13-game winning streak.

The Southeastern Conference has won the last six BCS championships, but with Alabama losing and three other teams unbeaten, it will be tough for the SEC to even get in the game without help.

Alabama would likely need to win out and have two of those three teams lose to reach the national title game.

No. 3 Kansas State 23, TCU 10

Collin Klein ran for two touchdowns and No. 3 Kansas State bolstered its national title hopes with a 23-10 victory at Big 12 newcomer TCU.

The Wildcats improved to 10-0 for only the second time under coach Bill Snyder, and moved within two wins of likely reaching their first BCS championship game.

TCU (6-4, 3-4 Big 12) didn't take advantage of Klein's interception on the fourth play of the game. The Heisman Trophy hopeful then hit Chris Harper for a 62-yard pass, and ended that drive with a 7-yard TD run.

No. 7 Florida 27, La.-Lafayette 20

Jelani Jenkins returned a blocked punt 36 yards for a touchdown with 2 seconds remaining and Florida rallied in the closing minutes to avoid a huge upset.

Florida (9-1) did little on offense most of the day and looked to be in serious trouble when quarterback Jeff Driskel left the game with an ankle injury.

No. 10 Clemson 45, Maryland 10

Tajh Boyd threw for 261 yards and three touchdowns as Clemson won its sixth straight and record 12th in a row at Death Valley.

Clemson (9-1, 6-1 Atlantic Coast Conference) had little trouble with the banged-up Terps (4-6, 2-4), who again started linebacker Shawn Petty at quarterback because of season-ending injuries to their four scholarship passers.

Syracuse 45, No. 11 Louisville 26

Ryan Nassib threw for 246 yards and three touchdowns, Jerome Smith ran for 144 yards and Syracuse handed Louisville its first loss of the season.

Playing in the last home game of his SU career, Nassib directed an offense that gained 524 total yards. Nassib went 15 of 23 and passed Donovan McNabb for second on the school's career yards passing list.

The Orange (5-5, 4-2 Big East) blew the game open with three touchdowns in the second quarter and Louisville (9-1, 4-1) allowed more points than it had in any game this season.

Teddy Bridgewater completed 36 of 49 passes for 426 and three touchdowns for Louisville.

No. 12 South Carolina 38, Arkansas 20

Connor Shaw threw for two touchdowns and ran for another score for South Carolina.

Shaw was 15 of 23 for 279 yards for the Gamecocks (8-2, 6-2 SEC), who finished with six league wins for only the second time in 20 years in the SEC.

Arkansas (4-6, 2-4) will now have to beat both Mississippi State and LSU to make a bowl game after starting the season No. 10 in the country.

No. 14 Oklahoma 42, Baylor 34

Landry Jones threw for 277 yards and two touchdowns, Damien Williams ran for 99 yards and two scores and Bob Stoops moved into sole possession of second place on the school's career wins list.

Backup quarterback Blake Bell scored on a 55-yard keeper in the fourth quarter for the longest run by a quarterback in the Stoops era.

Lache Seastrunk ran for 91 yards and three touchdowns for Baylor (4-5, 1-5 Big 12), the last score getting the Bears within eight with 1:26 to play after quarterback Nick Florence got in on the 2-point conversion.

LaColtan Bester recovered the ensuing onside kick, sealing the win for Oklahoma (7-2, 5-1).

No. 15 Stanford 27, No. 13 Oregon State 23

Kevin Hogan threw for 254 yards and three touchdowns in his first collegiate start, and Stanford overcame four turnovers to rally past Oregon State.

Cody Vaz fumbled late in the fourth quarter to give the Cardinal (8-2, 6-1) the ball at the Beavers 29. The only Oregon State (7-2, 5-2) turnover turned out to be the difference.

No. 18 Nebraska 32, Penn St. 23

Taylor Martinez threw a 5-yard touchdown pass to Jamal Turner for Nebraska's first lead, and the Cornhuskers overcame a double-digit, second-half deficit for the fourth time this season.

The Huskers (8-2, 5-1 Big Ten), down 14 points at half, got TD runs of 1 and 2 yards from Imani Cross to tie it at 20.

Martinez threw 56 yards to Kyler Reed on a third-and-5 and, three plays later, found Turner on a short slant in the end zone for the lead with 10:57 left.

No. 19 Texas 33, Iowa State 7

David Ash passed for 364 yards and two touchdowns and Texas honored former coach Darrell Royal by whipping Iowa State.

Ash had a 61-yard touchdown pass to Mike Davis in the first quarter. Johnathan Gray ran for two touchdowns for the Longhorns (8-2, 5-2 Big 12), who won their fourth in a row.

No. 21 USC 38, Arizona State 17

Marqise Lee caught 10 passes for 161 yards and a touchdown, Curtis McNeal rushed for 163 yards and two more scores, and Southern California bounced back from consecutive losses against skidding Arizona State.

Matt Barkley threw for 222 yards and three TDs while becoming the leading passer in conference history for the Trojans (7-3, 5-3 Pac-12), who overcame a slow start and five turnovers to snap their two-game skid. USC hasn't lost three straight since 2001, former coach Pete Carroll's first season.

No. 24 Rutgers 28, Army 7

Brandon Coleman caught his second touchdown of the game on a 31-yard pass from Gary Nova with 8:49 to play and Rutgers survived a valiant effort by mistake-prone Army.

In bouncing back from its first loss and a two-week layoff that featured Hurricane Sandy and a Nor'easter that dumped a foot of snow in New Jersey, the Scarlet Knights (8-1) scored three times in the final nine minutes. They also got a 2-yard touchdown run from Savon Huggins and a 73-yard fumble return by Duron Harmon in the final minute.

Army (2-8) played tough, but it could not overcome three lost fumbles, a dropped touchdown pass, two blocked field goals and three late game-changing miscues that cost them the game.

No. 25 Texas Tech 41, Kansas 34

Running back Eric Stephens threw a 3-yard jump pass to Darrin Moore for a touchdown in double overtime to lead Texas Tech past Kansas.

Kansas had a chance to tie but Michael Cummings couldn't connect with Tre' Parmalee in the end zone on fourth-and-9.
