LINCOLN, Neb. (AP) Rex Burkhead, who started the week with his right foot in a walking boot, ran for 160 yards and a touchdown on a school-record 38 carries and No. 22 Nebraska defeated Iowa 20-7 on Friday.

Burkhead pounded away at Iowa's defense 4 and 5 yards at a time and looked like his old self after being held to a season-low 36 yards in last week's loss at Michigan.

He had eight carries for 39 yards on a 10-play drive that ended with his 2-yard run and a 20-0 lead early in the fourth quarter.

The Hawkeyes (7-5, 4-4) avoided getting shut out for the first time in 11 years when Marcus Coker scored on a 2-yard run with 3:26 left.

Nebraska (9-3, 5-3) is hoping to land a berth in the Capital One Bowl, if two Big Ten teams are invited to BCS games, or the Outback Bowl.
