Chris Tyree returned a kickoff 96 yards for a touchdown and Drew Pyne threw a fourth-quarter touchdown pass in relief of an injured Jack Coan, helping No. 12 Notre Dame pull away from No. 18 Wisconsin 41-13 on Saturday at Soldier Field.

The Fighting Irish (4-0) have shown plenty of vulnerabilities as they retooled a team that went to the College Football Playoff last season. But they keep winning.

With victory No. 106 in 12 seasons at Notre Dame, Brian Kelly (106-39) surpassed the legendary Knute Rockne (105-12-5).

“We got a long way to go still, but they’re getting better each week,” Kelly said. “I’m having fun coaching them. They’re not perfect by any means, but they’re going to be better in November.”

“Last year we were a veteran team. We hunkered down, we put three tight ends on the field. This is what we were and kind of lived with it,” Kelly said. “This is, like, we’re trying to figure it out as we go.”

Graham Mertz threw four interceptions for Wisconsin (1-2), including two that were returned for touchdowns in the final 2:30 to blow the game open. Notre Dame scored the final 31 points and the Badgers lost their seventh straight to a ranked team.

Running back Chez Mellusi called the collapse “embarrassing.”

Coan, a Wisconsin transfer, left with a left leg injury in the third quarter with the game tied at 10. Kelly said it was a soft tissue injury, but didn’t appear to be a severe ankle sprain.

“”Jack Coan is our starter,” Kelly said. “If he’s physically able, he’ll be our starter against Cincinnati.”

Notre Dame had used freshman Tyler Buchner as a mobile complement to Coan the last two games, but he was dealing with a sore hamstring. So it was Pyne’s turn to step up.

Pyne lost a fumble on his second possession, leading to a field goal by the Badgers, but otherwise the redshirt freshman was solid, going 6 for 8 for 81 yards.

Purdue 13, Illinois 9: Aidan O’Connell hooked up with T.J. Sheffield on a 14-yard scoring pass with 5:44 left to play for the game’s only touchdown, giving Purdue a victory over rival Illinois.

The Boilermakers (3-1, 1-0 Big Ten) rebounded from their only loss of the season by claiming the Cannon Trophy for the second straight year.

Illinois (1-4, 1-2) has lost four in a row since beating Nebraska in the season opener.

O’Connell replaced starter Jack Plummer in the third quarter and immediately gave the Boilermakers’ short-handed offense a spark although his first two series ended with interceptions. He then led Purdue on a 94-yard scoring drive — its longest of the season — to retake the lead.

Purdue’s defense closed it out by forcing a turnover on downs in its own red zone.

Jeff McCort made three field goals for Illinois, the third a 45-yarder 9 seconds into the fourth quarter for a 9-6 lead. But the Illini defense couldn’t protect the lead.

Northwestern 35, Ohio 6: Evan Hull rushed for 216 yards and a pair of touchdowns to lead Northwestern to a win over Ohio.

Hull bounced off a defender at the line of scrimmage late in the first quarter before sprinting away for a 90-yard score that helped set the Wildcats (2-2) up for their first win over an FBS team this season.

“I don’t think ever in my career have I had a 90-yard touchdown,” said Hull, who tumbled in after a swipe from a Bobcats defender. “Toward the end I just made up my mind no matter what happens, I’ve got to get into the end zone.”

The Wildcats’ ground game amassed 373 yards to take the pressure off sophomore Ryan Hilinski, who completed just 12 passes for 88 yards in his first start replacing Hunter Johnson.

Bowling Green 14, Minnesota 10: Quarterback Matt McDonald ran for a pair of scores, and two late interceptions by the Bowling Green defense sealed the win as the Falcons shocked heavily-favored Minnesota, on homecoming.

The loss snapped Minnesota’s streak of 21 straight non-conference wins, the longest streak in the country entering Saturday’s game. The Gophers’ last non-conference loss was Sept. 3, 2015 against TCU.

It also marked Minnesota’s first loss to a non-Power 5 conference opponent since losing to North Dakota State on Sept. 24, 2011.
