Penn State, Michigan get into it in the tunnel at halftime (0:28)

In the tunnel at halftime, Penn State and Michigan talk. There is a 0:28

6:00 PM ET

The Lloyd Carr Tunnel at Michigan Stadium was named after Michigan coach Lloyd Carr after Saturday's game.

The teams entered the tunnel at the same time, with the Wolverines leading 16-14 at the half. The situation never became physical despite the video showing the teams exchanging words.

McCarthy said that he wouldn't be surprised if it was the other way around. We just completed it.

The standoff was caused by Penn State players talking trash on social media before the game, according to Mike Morris.

They didn't talk on the field because they didn't want to use social media. They wanted to talk at the half time table.

After dominating the stat sheet but not the score in the first half, the fifth-ranked Wolverines finished No. 10 Penn State with a resounding third quarter. Michigan held a huge advantage in rushing yards, first downs, and possession time.

In a game in which Penn State had more touchdown (2) than first downs (1), Michigan looked like the defending Big Ten champion and a team poised to push Ohio State for the league crown and a likely College Football Playoff spot.

McCarthy said that Harbaugh said in the locker room that it was a butt- kicking. It was great to be able to do it in the fashion that we did. They only had one first down and we had 18 in the first half. Any day of the week, we will take that.

Harbaugh said that he preferred Michigan's line-of-scrimmage dominance to win games. Michigan had not been fully branded a contender because of its competitors. Penn State came in with a perfect record, but was no match for the Michigan team.

Harbaugh said the team made a good statement. It's called a statement game? It is a statement game.

Harbaugh's team wasn't concerned at halftime, even though it led by only two points after holding Penn State quarterback Sean Clifford to 17 passing yards, the lowest for a Nittany Lion starter since at least 2004.

Penn State gave up more rushing yards to Michigan than it had in the previous five games. In the first half, Michigan's inability to convert red zone opportunities into points was a problem, but in the third quarter, it was the other way around.

"I feel like I've been ready for a game like this for a while now, I missed two games with a leg injury in September, but I feel like I'm good to go for this one," he said. I had to sit back and wait and see what I could do.

In the past four games, Corum has 666 rushing yards, the most by a Michigan player since Denard Robinson in 2010 and the most by a UM running back since Mike Hart in 2004. Hart had a medical emergency on the sideline last week at Indiana and had to be hospitalized.

They became the first Michigan tandem to each eclipse 150 rushing yards and record multiple rushing touchdown in the same year.

Harbaugh said that the two guys were fast. They roll when they get in the open.

McCarthy picked off a pass at Indiana and returned it for a touchdown in the second quarter. He ran for 57 yards in the win and had a season-low 145 passing yards.

McCarthy says he needs to use his legs more. I should be able to do it because I'm faster than Joe Burrow and he was able to do it.

Drew Allar replaced Clifford in the second half and completed 5 of 10 passes for 37 yards and a touchdown. Michigan had a lot of quarterback hurries.

Penn State had 49 net rushing yards on 21 carries.

"People look at it as we haven't played anyone, but in reality, we have, and we showed up and showed out," said Morris, who had a tackle for loss. We showed up and people said we hadn't played anyone. The narrative can continue, but we have to prove people wrong.
