Paul Dawson returned an interception 41 yards for a touchdown, TCU made a huge fourth-and-1 stop with just over 3 minutes left and the No. 25 Horned Frogs remained undefeated with a 37-33 victory over No. 4 Oklahoma on Saturday at Amon G. Carter Stadium in Fort Worth, Texas.

Oklahoma (4-1, 1-1 Big 12) had the ball after the teams had three turnovers in a span of four plays - another interception by Trevor Knight between two fumbles by TCU.

Trevone Boykin, the dual-threat quarterback flourishing in TCU's new offense, was 20-of-38 passing for 318 yards with two touchdowns, and added 77 yards on 22 carries.

TCU improved to 4-0 for the fifth time in the last seven seasons under coach Gary Patterson, but this was the kind of big attention-grabbing victory the Horned Frogs didn't have in their first two Big 12 seasons.

After winning three consecutive Mountain West titles, the Frogs moved to the power conference and went 6-12 in league games the first two seasons. They made quite a statement in their third league opener - and provided a jolt to Oklahoma's standing for the new four-team College Football Playoff, though the Sooners weren't the only highly ranked team to lose to start October.

Notre Dame 17, Stanford 14 - Everett Golson threw a 23-yard touchdown pass to Ben Koyack in the corner of the end zone with 61 seconds left as the No. 9 Irish overcame two turnovers and two bungled snaps on field goal attempts on a cold, rainy day in South Bend to beat the No. 14 Cardinal.

The Fighting Irish improved to 5-0 for just the third time since Lou Holtz left in 1996. The other two times were in 2002, when they started 8-0 in Tyrone Willingham's first year as coach, and two seasons ago, when they had an undefeated regular season. The Cardinal (3-2) have two losses this early in the season for the first time since opening 1-2 in 2008 in Jim Harbaugh's second season as coach.

Golson was 20-of-43 passing for 241 yards with one interception and a fumble a week after having four turnovers against Syracuse. Notre Dame, which entered the game 2.5-point underdogs, won at home for the 16th time in the last 17 games.

Mississippi State 48, Texas A&M 31 - Dak Prescott threw two touchdown passes, added three Tebow-style TD runs, and the No. 12 Bulldogs overwhelmed the No. 6 Aggies in Starkville, Miss., as a new contender emerged in the SEC West.

The Bulldogs (5-0, 2-0 Southeastern Conference) jumped out to a 28-7 lead in the first half and never let Kenny Hill and the high-scoring Aggies (5-1, 2-1) get close enough to threaten the lead - or quiet the Bulldogs fans and their clanging cowbells at Davis Wade Stadium.

Hill threw for 365 yards and four touchdowns, but was picked off three times by linebacker Richie Brown, who matched a school record.

Northwestern 20, Wisconsin 17 - Godwin Igwebuike had three interceptions, and Justin Jackson rushed for 162 yards, helping the resurgent Wildcats upset Melvin Gordon and the No. 17 Badgers in Evanston, Ill.

Gordon had 27 carries for a career-high 259 yards and a touchdown, but Wisconsin (3-2, 0-1 Big Ten) had just 138 yards passing against Northwestern (3-2, 2-0) on a cold, damp afternoon at Ryan Field.

Michigan State 27, Nebraska 22 - Trae Waynes intercepted Tommy Armstrong's pass with 30 seconds remaining, and the No. 10 Spartans held off a furious Big Red rally, beating the No. 19 Cornhuskers in East Lansing, Mich.

The Spartans (4-1, 1-0 Big Ten) led, 27-3, heading into the fourth quarter before three Nebraska touchdowns set up a tense finish.

But on a day when several other top teams lost in wild upsets, Nebraska (5-1, 1-1) couldn't finish this comeback.

Armstrong's pass to the end zone fell incomplete, and Waynes then came up with his second interception of the game.

Arizona State 38, Southern California 34 - Jaelen Strong, a former West Catholic star, caught a 46-yard touchdown pass from Mike Bercovici as time expired, and the visiting Sun Devils scored three TDs in the final 3:53 to shock the No. 16 Trojans.

Arizona State's bench stormed the field to celebrate the first win at the Coliseum since 1999 for the Sun Devils (4-1, 2-1 Pac-12).

Strong caught 10 passes for 202 yards and three touchdowns.

Cody Kessler passed for 273 yards for the Trojans (3-2, 2-1), who led 34-25 with 3 minutes to play.
