IOWA CITY, Iowa --- No. 8 Iowa finally ran out of time.

Dan Persa threw a touchdown pass and Marshall Thomas recovered a fumble for another score, and Northwestern snapped the Hawkeyes' 13-game winning streak with a 17-10 victory Saturday.

It was the first win over a top-10 opponent for the Wildcats (6-4, 3-3 Big Ten) since knocking off then-No. 6 Ohio State 33-27 in overtime in 2004. It also ended the nation's second-longest winning streak.

Iowa played without starting quarterback Ricky Stanzi after he sustained an apparent ankle injury early in the second quarter. Freshman James Vandenberg was just 9 of 27 for 82 yards and couldn't lead the Hawkeyes (9-1, 5-1) to any points after Stanzi left the game.

NO. 2 TEXAS 35, CENTRAL FLORIDA 3

In Austin, Texas, Jordan Shipley set a Texas record with 273 yards receiving, including an 88-yard touchdown, and the Longhorns shook off a slow start for a win over Central Florida.

Colt McCoy passed for 470 yards with two touchdowns for Texas (9-0), which led 14-3 at halftime on two touchdown runs by Cody Johnson.

NO. 6 TCU 55, SAN DIEGO STATE 12

In San Diego, Andy Dalton threw two touchdown passes and ran for two more for the Horned Frogs, who won their 11th consecutive win.

STANFORD 51, NO. 7 OREGON 42

In Stanford Calif., Toby Gerhart bowled over the Oregon defense to make the Cardinal (6-3, 5-2 Pac-10) bowl eligible for the first time in eight years.

The loss by Oregon (7-2, 5-1 Pac-10) just a week after beating Southern California 47-20 opened up the conference race and cost the Ducks a shot at a berth in the Bowl Championship Series title game.

NO. 13 HOUSTON 46, TULSA 45

In Tulsa, Okla., Matt Hogan kicked a 51-yard field goal as time expired to lift Houston to a victory, finishing off another thrilling comeback led by Heisman Trophy candidate Case Keenum.

The Cougars (8-1, 4-1 Conference USA) rushed onto the field and hoisted Hogan into the air after he connected on the longest kick of his career. He hadn't made a field goal of longer than 34 yards before his game-winner.

NO. 14 PITTSBURGH 37, SYRACUSE 10

In Pittsburgh, Greg Williams' 51-yard interception return for a touchdown late in the first half got slow-starting Pittsburgh going, as the Panthers extended their best start to a season since 1982 by beating Syracuse.

The Panthers (8-1, 5-0 in Big East) won their fifth in a row.

NO. 17 UTAH 45, NEW MEXICO 14

In Salt Lake City, Jordan Wynn passed for 297 yards and two touchdowns in his first college start and Eddie Wide set a school record with his sixth consecutive 100-yard rushing game.

In Bloomington, Ind., John Clay ran for 134 yards and a touchdown, Montee Ball scored two TDs and the Badgers (7-2, 4-2 Big Ten) held off the Hoosiers' fourth-quarter rally.

NO. 25 BYU 52, WYOMING 0
