COLUMBUS, Ohio -- Chris Gamble began Saturday as Ohio State's first two-way starter in 39 years. He left with a record crowd chanting his name.
On a day when freshman running back Maurice Clarett injured his shoulder and missed most of the game, Gamble's performance was something to shout about.
The receiver made a stellar debut as a starting defensive back by returning an interception for a touchdown and preventing a score with a tackle in Ohio State's 13-7 win over Penn State.
"It feels good to get my name chanted by the crowd," the soft-spoken Gamble said after he was hailed by 105,103, the most fans ever at Ohio Stadium.
The Nittany Lions had five first downs and 179 total yards.
"We got licked," Penn State coach Joe Paterno said.
Clarett, who missed a game this season with a knee injury, hurt his left shoulder six plays in and did not return. He had averaged 140 yards and was off to another fast start, gaining 39 yards on four carries to give him 1,019 yards in just over seven games.
Ohio State coach Jim Tressel said he was unsure of the nature or the severity of the injury.
"I can't tell you if it's a one-day thing or a five-day thing," he said.
Ross was replaced by Tampa Gaither graduate Lydell Ross, who gained 40 yards on 21 carries.
Gamble became the first Ohio State player since Paul Warfield in 1963 to start on both sides of the ball. Gamble entered as the Buckeyes' second-leading receiver and lately had been called on more and more to help the thin, inexperienced cornerback unit.
With Ohio State trailing 7-3 early in the third quarter, Gamble picked off an underthrown floater by quarterback Zack Mills. Gamble raced down the right sideline, cut to the inside briefly, then sidestepped a tackler to slide into the end zone for a 40-yard score.
IOWA 34, MICHIGAN 9: The visiting Hawkeyes won so comfortably that they were able to celebrate and sing with their fans in a near-empty Michigan Stadium.
"I enjoyed that," Iowa coach Kirk Ferentz said. "I'd be lying if I said I didn't."
Brad Banks threw three touchdowns for the Hawkeyes, who scored 21 straight after Markus Curry fumbled a punt return in the third quarter, just after the Wolverines cut the deficit to 10-9.
The Wolverines hadn't lost by more at home since Michigan State beat them 34-0 on Oct. 14, 1967.
The Hawkeyes are in good position to at least earn a share of the conference title, with home games left against Wisconsin and Northwestern before the regular-season finale at Minnesota. Ohio State is not on their schedule.
To earn a spot in the Rose Bowl, the Hawkeyes must win their final three and Ohio State must lose at least once, because the Buckeyes would win the tiebreaker with a better overall record.
Banks went 18-of-29 for 222 yards. Two of his scores went to C.J. Jones, who caught eight passes for 81 yards, and the third was to Jermelle Lewis.
The Wolverines took advantage of a break in the second quarter. David Bradley fumbled a punt snap, which gave Michigan the ball at the Iowa 1. Chris Perry scored with 1:13 left in the half but Philip Brabbs missed the extra point.
Adam Finley, the third kicker Michigan has used this season, made a 40-yard field goal on his first career attempt early in the third to cut the deficit to 10-9.
Michigan forced a punt on the ensuing possession, but Curry fumbled the return.
Three plays later, Banks threw a 3-yard score to Jones to put Iowa ahead 17-9.
PURDUE 42, NORTHWESTERN 13: Brandon Jones and Joey Harris ran for more than 100 yards apiece and the Boilermakers totaled 407 on the ground for their first road win in more than a year.
The Boilermakers enjoyed their most productive running day since 1994 against the team that came in ranked last against the run among the 117 Division 1-A teams.
Jones rushed for a career-best 165 yards and Harris gained 132 and scored twice. Jerod Void ran for two touchdowns and freshman quarterback Brandon Kirsch threw for two.
Northwestern lost its fifth straight and 10th in a row in the conference. It gave up more than 40 points for the third week in a row and fifth time this year.
ILLINOIS 45, INDIANA 14: Antoineo Harris ran for a career-high four touchdowns and 176 yards for the host Illini. Harris scored from 1, 4, 28 and 5 yards and was taken out after playing one series in the second half. Indiana scored two touchdowns late.
Illinois quarterback Dustin Ward, making his second start since he was benched earlier in the season, threw two touchdowns and was 16-of-23 for 197 yards.
WISCONSIN 42, MICHIGAN ST. 24: Brooks Bollinger threw three touchdowns and ran for two others for the visiting Badgers.
Bollinger, knocked out of the previous week's loss to Ohio State with a concussion, led the Badgers to touchdowns on three of their five first-quarter possessions. Wisconsin gained 313 yards on the ground, including 170 by Anthony Davis and 110 by Dwayne Smith.
Michigan State has been outscored 114-47 in its past three games.
