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.

CANCUN, Mexico (AP) — Oderah Chidom had 12 points with 11 rebounds and No. 15 Duke cruised to an 86-48 victory over Iowa State at the Cancun Challenge on Friday. Chidom was 6 of 7 from the floor with three assists. Rebecca Greenwell scored 15 points and Azura Stevens chipped in 14 for Duke (5-1). Bryanna Fernstrom scored 15 points on 6-of-9 shooting to lead Iowa State (2-2).

The Cyclones had an early 9-5 lead before the Blue Devils used an 8-4 surge to take a 13-9 first quarter lead, and stretched it to 39-24 at halftime. Duke outscored the Cyclones 29-9 in the fourth quarter, bouncing back after allowing Idaho 19 fourth-quarter points in a 74-68 win on Thursday.

Duke is 3-0 against the Cyclones, and 8-0 in games played in Cancun. The Blue Devils face Texas State on Saturday.

AUSTIN, Texas (AP) — Jonquel Jones scored 23 points, including the go-ahead bucket, and had a school record 26 rebounds to lift No. 24 George Washington past No. 25 Iowa for an 81-77 double-overtime win in the Lone Star Showcase on Friday.

Tied at 73 with 1:28 left in the second overtime period, Jones sank back-to-back baskets to build the margin George Washington (5-1) held the rest of the way. Jones’ rebound total broke a school record that had stood since 1976.

Iowa (5-1) trailed by as much as eight in the fourth quarter but forced overtime with a layup from Chase Coley to tie it at 64. The Hawkeyes quickly edged ahead before Jones forced the second OT with a layup that tied it at 69.

Brianna Cummings added 13 points, Hannah Schaible had 12, Caira Washington 11 and Lauren Chase 10.

Coley led Iowa with 22 points and 10 rebounds.
