LINCOLN, Neb. (AP) — Jordan Canzeri broke long touchdown runs on back-to-back series in the third quarter, and No. 3 Iowa completed its first perfect regular season in 93 years with a 28-20 victory over Nebraska on Friday.

The Hawkeyes (12-0, 8-0, No. 4 CFP) were far from dominant but good enough against the sloppy Cornhuskers (5-7, 3-5) on a raw afternoon. As one of two remaining unbeaten teams, they’ll head to next week’s Big Ten championship game in the middle of the College Football Playoff race.

Canzeri ran off left tackle two straight times for two touchdowns, the first one going 29 yards and the second 68 yards for a 28-17 lead. Canzeri finished with 140 yards on 17 carries.

Iowa picked off Tommy Armstrong Jr. four times, with defensive end Parker Hesse returning one 4 yards for the Hawkeyes’ fourth interception for a touchdown this season. The Huskers needed a win to assure bowl eligibility.
