EAST LANSING, Mich. — Leo Musso returned a fumble 66 yards for a touchdown in the third quarter and No. 11 Wisconsin turned its early showdown with No. 8 Michigan State into a rout, beating the Spartans 30-6 on Saturday.

Redshirt freshman Alex Hornibrook threw for 195 yards and a touchdown in his first start for Wisconsin, outplaying fifth-year senior Tyler O’Connor, his Michigan State counterpart. The Badgers (4-0, 1-0 Big Ten) were the better team in the first half and outscored the Spartans 17-0 in the third quarter.

Michigan State (2-1, 0-1) was down 13-6 early in the third and had the ball in Wisconsin territory when LJ Scott’s fumble bounced to Musso in the secondary. O’Connor was the only player with a decent shot at him on the return, and Musso spun past the quarterback and went all the way to the end zone.

No. 7 Stanford 22, UCLA 13

PASADENA, Calif. — J.J. Arcega-Whiteside caught an 8-yard touchdown pass from Ryan Burns with 24 seconds left, and No. 7 Stanford rallied on its final drive for its ninth consecutive victory over UCLA.

Christian McCaffrey rushed for 138 yards for the Cardinal (3-0, 2-0 Pac-12), who haven’t lost to their downstate rivals since 2008.

After struggling on offense for 3 1/2 quarters at the Rose Bowl, Stanford put together a 70-yard winning drive capped by Burns’ fade to Arcega-Whiteside, who got one foot inbounds on an acrobatic play. Solomon Thomas then returned Josh Rosen’s fumble 42 yards for a touchdown on the game’s final play.

No. 1 Alabama 48, Kent St. 0

TUSCALOOSA, Ala. — Jalen Hurts ran and threw for touchdowns and tailback sub Joshua Jacobs scored his first two career touchdowns for Alabama.

The Crimson Tide (4-0) dominated coach Nick Saban’s alma mater from the start while scoring on a kickoff return and even a short touchdown throw to freshman linebacker Mack Wilson. Starting tailback Damien Harris went down on the opening drive with a sprained right ankle and didn’t return.

Harris was hardly needed in this game, when No. 2 quarterback Blake Barnett played much of the way and the emerging freshman Jacobs ran for 97 yards.

No. 3 Louisville 59, Marshall 28

HUNTINGTON, W.Va. — Lamar Jackson threw five touchdown passes and ran for two more scores for Louisville.

The sophomore completed 24 of 44 passes for a career-high 417 yards against a Marshall secondary whose most experienced player had five starts. Jackson also ran for 62 yards.

Louisville (4-0) didn’t slow down against a nonconference opponent on the road a week after beating Florida State 63-20 at home.

The Cardinals raced to a 35-7 halftime lead and cruised in the second half to break a four-game losing streak to the Thundering Herd. Jackson’s scoring passes covered 71, 8, 30, 8 and 51 yards.

No. 4 Michigan 49, Penn St. 10

ANN ARBOR, Mich. — De’Veon Smith led an overwhelming ground game with 107 yards rushing and a touchdown and Karan Higdon ran for two scores for Michigan in the Big Ten opener for both teams.

The Wolverines (4-0) had six touchdowns on the ground and finished with 326 yards rushing. Wilton Speight threw one touchdown pass. Penn State (2-2) has lost three straight to the Wolverines.

Jabrill Peppers gave the fans an early thrill by returning Penn State’s first punt to the 9, although a bench-interference penalty moved the ball to the Nittany Lions 24. Seven plays later, Khalid Hill dove in on 4th-and-goal from the 1.

No. 6 Houston 64, Texas St. 3

SAN MARCOS, Texas — D’Eriq King caught a touchdown pass, threw one and returned a kickoff for another score in Houston’s blowout victory.

King, a freshman recruited to play quarterback, is playing at wide receiver while Greg Ward Jr. directs the offense. Ward passed for two touchdowns and ran for one before leaving the game after playing one series in the third quarter. He completed 20 of 26 passes for 289 yards.

King made a mistake by calling for a fair catch on the Houston 5 during a first-quarter Texas State punt. He soon compensated for that, however, catching a short pass from Ward on a bubble screen and taking it in for a touchdown from 48 yards out. Early in the second quarter, King took a handoff from Ward and threw a high pass to the end zone that Steven Dunbar pulled in for a 15-yard touchdown.

No. 10 Texas A&M 45, No. 17 Arkansas 24

ARLINGTON, Texas — Trevor Knight had two long touchdowns runs for Texas A&M before halftime and threw a 92-yard pass to Josh Reynolds right after Arkansas was stopped three times from the 1.

Reynolds caught the ball in stride just short of midfield, and quickly shed defensive back DJ Dean on his way to the end zone to break a 17-all tie and put the Aggies (4-0, 2-0 Southeastern Conference) ahead to stay. Texas A&M has won five straight against the Razorbacks (3-1, 0-1), all since joining the SEC.

The long catch-and-run by Reynolds came two plays after Keon Hatcher was tackled for a 5-yard loss on fourth down, ending a 19-play drive for the Razorbacks that took 10 minutes after Texas A&M had fumbled from the Arkansas 2.

No. 13 Florida St. 55, South Florida 35

TAMPA, Fla. — Dalvin Cook rushed for a career-high 267 yards and two touchdowns and Florida State rebounded from the most lopsided loss in school history to beat South Florida.

Cook scored on a 75-yard run on the Seminoles’ first play from scrimmage, an immediate response to USF starting the game with Quinton Flowers and Rodney Adams teaming on an 84-yard catch-and-run for a 7-0 lead. The 213-pound junior’s rushing total on 28 carries topped his previous best of 266 yards against South Florida last year.

Florida State (3-1) bounced back from being trounced 63-20 by Louisville, a road shellacking that dropped the Seminoles 11 spots in the AP Top 25 from No. 2. South Florida (3-1) is off to its fastest start since 2011, however the Bulls were no match for a talented bunch that began the season with expectations of contending for its second national title in four years.

No. 14 Tennessee 38, No. 19 Florida 28

KNOXVILLE, Tenn. — Joshua Dobbs accounted for five second-half touchdowns and Tennessee overcame a 21-point deficit to beat Florida and end an 11-game losing streak in the series.

Tennessee (4-0, 1-0 Southeastern Conference) beat Florida (3-1, 1-1) for the first time since a 30-28 victory in 2004. The Volunteers lost by a single point each of the last two years.

This time, Tennessee delivered the comeback by scoring 38 consecutive points.

Dobbs threw four touchdown passes and ran for a fifth score — all in the second half. He was 16 of 32 for 319 yards with four touchdowns and two interceptions. Dobbs also ran for 80 yards and a touchdown.

No. 16 Baylor 35, Oklahoma St. 24

WACO, Texas — Seth Russell threw four touchdown passes, including an 89-yarder to Chris Platt for the go-ahead score in the third quarter, and Baylor beat Oklahoma State in the weather-delayed Big 12 opener for both teams.

The game was stopped by lightning for about 1 1/2 hours after the Bears scored on the opening series.

Ishmael Zamora had career highs of 175 yards receiving and two touchdowns on eight catches in his season debut for the Bears after a three-game suspension over a video of him whipping his dog that surfaced during the summer. Platt also had two TDs. Baylor earned its fourth consecutive 4-0 start in its first big test after a light nonconference schedule.

Auburn 18, No. 18 LSU 13

AUBURN, Ala. — Daniel Carlson kicked six field goals and Auburn beat LSU after officials ruled Danny Etling’s apparent last-gasp scoring pass came after time expired.

Etling rolled to his right and found D.J. Shark on a 15-yard pass, setting off a celebration by LSU players. Officials ruled time expired before Etling took the snap.

The celebration shifted to the Auburn sideline when officials announced the decisive ruling.

It was an important win for Auburn (2-2, 1-1 Southeastern Conference) and coach Gus Malzahn, who faced increased criticism following losses to Top 25 opponents Clemson and Texas A&M.

No. 20 Nebraska 24, Northwestern 13

EVANSTON, Ill. — Tommy Armstrong Jr. threw for 246 yards and ran for a career-high 132 to lead Nebraska past Northwestern in the Big Ten opener for both teams.

The Cornhuskers (4-0) remained unbeaten coming off a tight win over Oregon that vaulted them into the Associated Press Top 25 for the first time since December 2014.

They lost two fumbles near the Northwestern goal line in the first half, but scored two touchdowns in the third quarter to stretch their lead from three to 11.
