No. 4 Michigan won Saturday with heart for Mike Hart.

After the running game coordinator collapsed on the sideline in the first quarter, the Wolverines regrouped at halftime, returned to Wolverines football and performed like Hart wanted.

Cornelius Johnson’s 29-yard touchdown reception early in the third quarter gave Michigan the lead and the jolt it needed Saturday to celebrate a 31-10 victory over pesky Indiana without their beloved coach.

“During the game Mike had a medical emergency, he’s in stable condition and he’s going to stay overnight here in Bloomington for observation,” head coach Jim Harbaugh said. “Talking about Mike and his health, all our prayers go out to him.”

Hart’s absence dampened a historic day for the Wolverines (3-0 Big Ten) who improved to 6-0 for the second straight season — something they last did in 1976-77.

But the frightening, first-quarter sideline scene certainly took its toll on Michigan.

The school’s career rushing leader went down unexpectedly moments after the Hoosiers tied the score at 7, prompting Michigan’s players to clear the bench and spread out across the field. Some dropped to one knee as Harbaugh and other staff members watched trainers strap Hart to a backboard before carting him off the field.

Michigan wasn’t the same afterward.

The two teams traded field goals and blocked field goals before settling for a 10-10 halftime tie. The Wolverines didn’t reassert control until Johnson capped a 98-yard drive to start the second half with the first of two touchdown catches.

It was exactly what Michigan needed. Luke Schoonmaker and Johnson each caught fourth-quarter TD passes to seal the victory on a day J.J. McCarthy produced his first 300-yard game. The sophomore quarterback finished 28 of 36 with 304 yards, three TDs and one interception.

“It was good to see the young quarterback come of age today,” Harbaugh said. “Tough game, tight game, couldn’t lean on the ground game today and he did it.”

Rogers sets SEC passing record in win: Will Rogers threw for three touchdowns and broke the Southeastern Conference record for career completions, Dillon Johnson rushed for 100 yards and two scores, and No. 23 Mississippi State beat Arkansas 40-17 on Saturday.

Rogers was 31-of-48 passing for 395 yards and notched the record in the first quarter with the 922nd completion of his career, eclipsing the mark set by Georgia’s Aaron Murray in 52 games, Rogers has played in 28 games.

Rogers connected with Caleb Ducking, Austin Williams and Jaden Walley, and the Bulldogs (5-1, 2-1 SEC) rushed for over 100 yards for the second straight week for the first time in the Mike Leach era. Johnson is the first player under Leach in Starkville to hit the century mark.

Arkansas played without starting quarterback KJ Jefferson, who was dealing with an unspecified injury. Malik Hornsby was 8-of-17 passing for 234 yards in Jefferson’s absence, with one touchdown and two interceptions. He also rushed for 114 yards on eight carries.

MSU’s Mangham carted off against Ohio State: Michigan State safety Jaden Mangham was carted off the field with an injury against No. 3 Ohio State on Saturday.

Mangham appeared to take the brunt of a collision when he tackled Buckeyes running back TreVeyon Henderson late in the first quarter.

Mangham, a freshman, was put on a backboard and placed on the back of a cart, where Henderson gave him an encouraging tap. As the cart approached the tunnel, Mangham flashed a thumbs up for the cheering crowd.

Texas shuts out Oklahoma: Quinn Ewers never really considered whether he would be rusty after missing the last three games for Texas because of a collarbone injury that took him out against the nation’s top-ranked team.

The standout freshman quarterback was just ready to play against the Longhorns’ biggest rival — in what became an unprecedented romp over suddenly reeling Oklahoma.

“When coach told me, what was going through my mind was, ‘It’s time to go.’ That’s pretty much it,” Ewers said. “Growing up a fan, I always wanted to play in this one, so it’s pretty special.”

Ewers threw for 289 yards and four touchdowns in his return, Bijan Robinson ran for 130 yards with two TDs and the Longhorns handed Oklahoma its most-lopsided shutout loss ever, 49-0 on Saturday.

It was the first meeting between the Red River rivals since 1998 with neither ranked, and the highest-scoring game for Texas in the 118-game series that dates to 1900.
