IOWA CITY, Iowa: Dan Herron rushed for a 1-yard touchdown with 1:47 left as Ohio State beat Iowa 20-17 Saturday to keep its Rose Bowl bid alive. Terrelle Pryor threw for 195 yards and a touchdown for the Buckeyes, and had a 14-yard run on fourth down to keep the game-winning drive alive. Iowa went ahead 17-10 early in the fourth quarter on freshman Marcus Coker's 1-yard TD run. But Devin Barclay's 48-yard field goal brought the Buckeyes within 17-13, and Pryor engineered a 76-yard drive despite DeVier Posey's drop of a sure TD pass. No. 11 Michigan State 35, Purdue 31: In East Lansing, Michigan, Kirk Cousins lunged into the end zone from 3 yards out with 4:32 remaining as Michigan State also kept its Rose Bowl hopes alive by rallying to beat Purdue. The Spartans trailed 28-13 after three quarters and 31-20 midway through the fourth, but Cousins threw a 9-yard touchdown pass to Mark Dell with 6:54 remaining, and a 2-point conversion made it 31-28. Denicos Allen then blocked a punt, giving Michigan State the ball inside the 5 and setting up Cousins' touchdown. No. 6 Wisconsin 48, Michigan 28: In Ann Arbor, Michigan, Montee Ball and James White combined for 354 yards rushing and six touchdowns, leading Wisconsin one step closer to its first Big Ten championship since 1999. The Badgers, Ohio State and Michigan State are tied atop the Big Ten heading into the final weekend of the conference season. If Wisconsin beat Northwestern next week at home, they'll will win at least a share of the title and likely earn a trip to a BCS bowl.

No. 18 Texas 9, No. 9 Nebraska 6: In College Station, Texas, Cyrus Gray ran for a career-high tying 137 yards and Randy Bullock kicked the go-ahead field goal with about three minutes left.
