No. 5 Notre Dame 17, BYU 14

Theo Riddick pounded his way for a career-high 143 yards and Cierre Wood added 114 yards as Notre Dame overpowered a Brigham Young defense that entered the game third in the nation against the run, earning a victory Saturday.

Riddick had runs of 55 and 27, the two longest rushes of his career, to pace Notre Dame (7-0), which is off to its best start in a decade and has a big game ahead against No. 10 Oklahoma next week. The Cougars (4-4) fell to 0-3 on the road as they surrendered a season-high 270 yards rushing.

Backup quarterback Tommy Rees, starting in place of injured Everett Golson, completed 6 of 7 passes in the first quarter for 86 yards and a touchdown, throwing four of those to Tyler Eifert. But Rees missed his next seven passes and the Irish attempted only three passes in the second half.

Rees' only completion of the second half was a 31-yard pass to TJ Jones with a little more than a minute left in the third quarter. Riddick ran the ball up the middle for 19 yards to the BYU 5. Three plays later, George Atkinson III scored on an end around, cutting inside BYU safety Joe Sampson for the touchdown to give the Irish the 17-14 lead.

No. 1 Alabama 44, Tennessee 13

Amari Cooper caught two of A.J. McCarron's four touchdown passes as Alabama defeated Tennessee for its sixth consecutive victory over the Volunteers.

Cooper finished with seven receptions for 162 yards, including a 23-yard touchdown in the first quarter and a 42-yard score in the third. Cooper also had a 30-yard touchdown nullified by a penalty.

McCarron went 17-of-22 for a career-high 306 yards for Alabama (7-0, 4-0). T.J. Yeldon rushed for 129 yards and two touchdowns.

Tennessee (3-4, 0-4) has lost 11 of its last 12 SEC games and is 0-14 against the Top 25 since Derek Dooley took over the program in 2010.

Dooley returned to the sideline Saturday on crutches, less than two weeks after undergoing surgery on a fractured right hip. He had coached from the press box last week in a 41-31 loss at Mississippi State.

No. 3 Florida 44, No. 9 South Carolina 11

Florida lived up to its surprising BCS ranking by thrashing a South Carolina team that appeared to be a contender in the SEC.

The Gamecocks gave LSU almost all it could handle in Death Valley last week, and figured to follow up with a good showing in The Swamp.

Instead, Loucheiz Purifoy knocked the ball out of South Carolina quarterback Connor Shaw's hands on the first play, and Florida punched it in to start a rout.

Jeff Driskel threw four touchdown passes - three of them after turnovers - and the Gators matched their win total from last season.

Tight end Jordan Reed, the former New London High School star, caught two of the touchdown passes.

No. 4 Kansas State 55, No. 17 West Virginia 14

Collin Klein ran for four touchdowns and threw three TD passes as Kansas State got little resistance from West Virginia in a 55-14 victory Saturday night that turned a matchup of Heisman Trophy contenders into campaign ad for the Wildcats' quarterback.

Klein was 19 for 21 for a career-high 323 yards and ran for 41 yards for the Wildcats (7-0, 4-0 Big 12).

It was no surprise the Mountaineers (5-2, 2-2) were awful on defense, it's been that way all season. For the second straight game, though, Geno Smith and the offense did nothing to keep it close.

No. 6 LSU 24, No. 20 Texas A&M 19

Jeremy Hill rushed for a career-high 127 yards and a touchdown, and the Tigers rallied from an early deficit.

Michael Ford also had a touchdown run and Zach Mettenberger threw a TD pass to Kadron Boone for the Tigers (7-1, 3-1 Southeastern Conference), who scored 21 points off four Texas A&M turnovers.

A&M (5-2, 2-2) outplayed the Tigers for much of the first half and led 12-0, LSU's largest deficit since the national championship game against Alabama in January. But the Aggies gave away two costly turnovers just before halftime, and Boone's diving catch in the end zone with 11 seconds left put LSU up 14-12 at the break. Hill finished off A&M with a 47-yard touchdown run in the fourth quarter.

No. 7 Ohio State 29, Purdue 22

Backup Kenny Guiton came off the bench in relief of injured Braxton Miller to lead touchdown drives in the final minute of regulation and Carlos Hyde scored on a 1-yard run in in overtime.

Purdue (3-4, 0-3 Big Ten) led 22-14 when Ohio State got the ball with just 47 seconds left in regulation. Guiton, inserted when Miller went out with an undisclosed injury, hit Chris Fields on a 2-yard touchdown pass with 3 seconds remaining. Guiton then found freshman Jeff Heuerman on the conversion pass to tie it at 22. Hyde scored on a short plunge for Ohio State (8-0, 4-0) before Purdue's Caleb TerBush, who had two TD passes, misfired on four passes in the overtime.

No. 10 Oklahoma 52, Kansas 7

Landry Jones threw for 291 yards and three touchdowns, and Oklahoma scored on a kickoff return and a punt return in the same game for the first time in school history while clobbering Kansas.

Justin Brown made up for a lost fumble on his previous punt return by running his next chance back 90 yards and diving at the pylon for the score. Roy Finch then opened the second half with a 100-yard runback to stretch the lead to 45-0.

No. 11 USC 50, Colorado 6

Matt Barkley threw for 298 yards and six touchdowns while setting Southern California's career record for TD passes, and Robert Woods caught a school-record four scoring passes while also surpassing USC's career receptions mark in the Trojans' victory over Colorado.

Barkley and Woods climbed atop the Trojans' record books during the most prolific day of their three-year partnership at USC (6-1, 4-1 Pac-12), connecting on scoring throws of 39, 29, 17 and 3 yards in the first 35 minutes against hapless Colorado (1-6, 1-3).

No. 13 Georgia 29, Kentucky 24

Aaron Murray threw four touchdown passes to rally Georgia to a victory over stubborn Kentucky.

The junior finished 30 of 38 for 427 yards as the Bulldogs (6-1, 4-1 SEC) stayed within reach of East-leading Florida entering next week's showdown against the Gators (7-0, 6-0) in Jacksonville, Fla.

Georgia, coming off a bye following a 35-7 loss at South Carolina, had to work hard to get past Kentucky (1-7, 0-5). Despite outgaining the Wildcats 504-316, the Bulldogs trailed three times and needed Murray's fourth TD for a cushion.

No. 14 Clemson 38, Va. Tech 17

Tajh Boyd ran for two touchdowns and passed for another and Jonathan Meeks had a 74-yard interception return score and the Tigers beat the Hokies for the third straight time.

Andre Ellington had a 12-yard touchdown run and 96 yards for the Tigers (6-1, 3-1 Atlantic Coast Conference), who relied on their much-maligned defense to bail them out of this one.

No. 15 Mississippi State 45, Middle Tennessee 3

Tyler Russell threw for 191 yards and three touchdowns, Johnthan Banks tied a school record with his 16th career interception and Mississippi State pulled away in the second half to beat Middle Tennessee.

Mississippi State (7-0) led just 10-3 at halftime, but scored three touchdowns in the third quarter to open a comfortable lead in the non-conference game. It was the ninth straight win for the Bulldogs, dating to last season.

No. 18 Texas Tech 56, TCU 53

Seth Doege threw seven touchdowns, three in overtime, and Texas Tech won at TCU after blowing a late 10-point lead.

The game-winning pass was an 8-yard throw to Alex Torres, which came four plays after Jaden Oberkrom's school-record sixth field goal had put TCU ahead. Both teams scored touchdowns in the first two overtime periods.

No. 22 Stanford 21, California 3

Stepfan Taylor ran for a career-high 189 yards and one touchdown, and Stanford got its third straight Big Game victory.

In the 115th meeting between the Bay Area schools and the first at remodeled Memorial Stadium, the sunny and serene Strawberry Canyon setting might have been Cal's best highlight. The Cardinal outgained the Golden Bears 475 to 217 yards, outrushed Cal 252 to 3 yards and never lost its grip on the coveted Stanford Axe.

No. 23 Michigan 12, Michigan State 10

Brendan Gibbons made a 38-yard field goal with 5 seconds left, helping the Wolverines (5-2, 3-0 Big Ten) beat the Spartans (4-4, 1-3) for the first time since 2007 to avoid a school-record, five-game losing streak in the series.

Denard Robinson threw a 20-yard pass to Drew Dileo to set up the game-winning kick.

No. 24 Boise State 32, UNLV 7

D.J Harper rushed for two touchdowns and a dominating defense added one of their own to help the Broncos to their sixth straight win since an opening loss at Michigan State.

Harper scored on a 10-yard run in the first quarter then again late in the third quarter from 1-yard out to put Boise State (6-1, 3-0 Mountain West) up 32-0 at the time.
