ANN ARBOR, Mich. (AP) -- One storied program salvaged its reputation against another trying to restore its lofty status.
Chad Henne threw his second touchdown pass to Mario Manningham from 10 yards out with no time left to lift Michigan to a thrilling 27-25 victory over No. 8 Penn State on Saturday.
"That's as wild a game as I've ever been in -- just unbelievable," Michigan coach Lloyd Carr said.
Michigan (4-3, 2-2 Big Ten) -- the winningest team in college football -- avoided its worst record in mid-October since 1967.
"It's a huge win," linebacker David Harris said. "It's a big turning point in our season."
The Nittany Lions (6-1, 3-1) are still off to their best start since 1999 but fell out of sole possession of first place in the conference with their seventh straight loss in the series.
"It was a great football game. Our kids hung in there," Nittany Lions coach Joe Paterno said quietly. "I'm proud of them. I'm disappointed for them."
Paterno didn't make his players available for comment -- just like he didn't the last time he faced Michigan in 2002, a 27-24 overtime loss on the road.
"You're going to ask them the same questions you'd ask me," Paterno explained.
Michael Robinson scored his second touchdown from 3 yards out with 53 seconds left to give the Nittany Lions a 25-21 lead, but Steve Breaston returned the kickoff to midfield to set up the game-winning score.
"We should've just power-kicked it to the other side," Paterno said. "He hurt us."
A second was left on the clock when Henne took the last snap and connected with Manningham in the middle of the end zone.
"Chad put it right there," Manningham said.
It couldn't have been a more exciting second half -- with both teams taking what appeared to be commanding leads -- after Michigan led 3-0 at halftime.
Penn State scored 15 points in 17 seconds -- on Robinson's 4-yard run, a fumble return and a 2-point conversion after a botched kick attempt -- to take an 18-10 lead early in the fourth quarter.
But Michigan quickly responded with Henne's 33-yard TD pass to Manningham and Mike Hart's 2-point conversion run to tie the game.
After forcing Penn State to punt, the Wolverines got the ball back at their 42.
Garrett Rivas easily made a 47-yard kick with 3:45 left to put Michigan ahead 21-18 one week after missing two field goals in the second half of a 23-20 loss to Minnesota.
Two plays later, Leon Hall stepped in front of Robinson's pass -- his first interception in 104 attempts -- and the Wolverines had the ball at Penn State's 40.
Michigan lined up for a 51-yard kick but had Rivas punt and it went just 16 yards to Penn State's 19.
With no timeouts left, the Nittany Lions drove down the field -- with Robinson running for a first down on a fourth-and-7 from Michigan's 39 -- and their elusive quarterback scored on his second draw for a go-ahead score.
"I thought the offense would cover us, they were covering for us throughout the game," Michigan defensive tackle Gabe Watson said.
The Wolverines then made just enough plays and had just enough time to earn the victory they -- and a much-maligned Carr -- desperately needed.
"Coach said the game was going to come down to a play like that, and it did, and we pulled it off," Watson said.
Hart ran for 108 yards and a score while Henne was 21-of-36 for 212 yards with two TDs and a fumble, which was ripped away by linebacker Alan Zemaitis and returned 35 yards for a go-ahead score.
Robinson completed 19-of-34 for 239 yards with an interception and ran for 67 yards with two scores and a fumble, Penn State's first turnover after 11 quarters without one.
Tony Hunt ran for 102 yards for the Nittany Lions, who lost freshman receiver Derrick Williams late in the fourth quarter with what appeared to be a left arm injury.
Despite battling the flu all week, Will Grier will start at quarterback for No. 25 Florida on Saturday when the Gators host No. 3 Ole Miss.
Florida State running back Dalvin Cook exited with a left leg injury in the first quarter of the Seminoles' 24-16 win over Wake Forest and did not return. He is day-to-day, Jimbo Fisher said.
Trevone Boykin threw five touchdown passes, including four to freshman KaVontae Turpin, and No. 4 TCU rode a 30-point first quarter to a 50-7 rout of Texas on Saturday.
As if things weren't going bad enough at Texas, the Longhorns appear to have players on Twitter during lopsided losses and jabs at their coach accidentally being sent from other nearby teams.
Tulane long-snapper Aaron Golub became the first legally blind person to play in a Division I football game Saturday, according to the school.
LJ Scott ran for 146 yards and two touchdowns, and No. 2 Michigan State held on through a lackluster second half to beat Purdue 24-21 on Saturday.
