ANN ARBOR, Mich. >> Kalel Mullings surged 2 yards for a touchdown run on fourth down with 37 seconds left, lifting No. 18 Michigan to a 27-24 win over No. 11 Southern California on Saturday, welcoming the Trojans to the Big Ten with a heavy dose of smashmouth football.

The Wolverines (3-1, 1-0) overcame losing a 14-0 lead in the first half and coughing up two fumbles in the second half. They won with a 10-play, 89-yard TD drive, with Mullings doing most of the work. He capped it with his second touchdown of the game, this one running behind a fullback in a jumbo package that left little doubt were they ball was going.

The Trojans (2-1, 0-1) went ahead 24-20 midway through the fourth when Miller Moss threw his third touchdown pass, a 24-yarder to Ja’Kobi Lane.

USC’s last chance ended with a fourth-down throw coming up short of the line to gain near midfield.

Mullings had a career-high 159 yards rushing, including a 53-yard scoring run to put the Wolverines ahead early, and Donovan Edwards had a 41-yard run to give them a two-touchdown lead.

No. 17 Notre Dame 28, Miami (ohio) 3 >> Riley Leonard accounted for 297 yards total offense and three touchdowns as No. 17 Notre Dame shook off a sluggish offensive start to beat Miami (Ohio).

The Cardinals (3-0, 1-0 ACC) used defense and offense to lead 17-7 in the second quarter before the Yellow Jackets rallied to tie the game at 17 late in the third. Louisville eventually went ahead on Tyler Shough’s deep pass to Brooks down the right sideline that Brooks hauled in on the run even as a Tech defender was called for pass interference.

No. 20 Iowa State 52, Arkansas State 7 >> Rocco Becht threw for two touchdowns and ran for another, and Carson Hansen rushed for two scores as No. 20 Iowa State rolled over Arkansas State.
