BIG TEN:?No. 3 Iowa 28, Nebraska 20

Jordan Canzeri broke long touchdown runs on back-to-back series in the third quarter, and Iowa completed its first perfect regular season in 93 years with a victory over host Nebraska.

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.

TOP 25:?No. 21 Houston 52, ?No. 16 Navy 31

Greg Ward, Jr. threw for 308 yards and three touchdowns and host Houston beat Navy to reach the first American Athletic Conference championship game.

Houston (11-1, 7-1 American) won the West Division title and will host either Temple or South Florida in the championship game Dec. 5.

The Cougars are also well positioned to earn a bid to a New Year’s Six bowl game, likely the Fiesta Bowl, if they win the league championship.

Ward was 26-of-35 passing and ran for 83 yards and another score. Brandon Wilson ran for 111 yards and two touchdowns on 22 carries.

Washington 45, ?No. 20 Washington State 10

Myles Gaskin rushed for 138 yards and two touchdowns, Sidney Jones, Darren Gardenhire and Azeem Victor all returned turnovers for touchdowns in the second half and host Washington became bowl eligible with a win over Washington State.

The Huskies (6-6, 4-5 Pac-12) took all debate out of their postseason status by stemming the best passing game in the country and taking advantage of seven turnovers by the Cougars, the most by Washington State since 2009 against Hawaii.

No. 18 Oregon 52, ?Oregon State 42

Vernon Adams threw for 366 yards and three touchdowns and host Oregon extended its winning streak to six games and closed out the regular season with a victory over the rival Oregon State Beavers in the 119th Civil War game.

Royce Freeman ran for 167 yards and two touchdowns for the Ducks (9-3, 7-2 Pac-12).

MID-AMERICAN:?Western Michigan 35, ?No. 24 Toledo 30

Corey Davis caught two touchdown passes and Western Michigan upset host Toledo to send Northern Illinois to the Mid-American Conference championship game.

The Rockets (9-2, 6-2) could have earned the MAC West title and a spot in the league title game, but the Broncos (7-5, 6-2) created a three-way tie for the division.

Central Michigan 35, ?Eastern Michigan 28

Romello Ross scored four touchdowns and host Central Michigan beat Eastern Michigan.

Eastern Michigan (1-11, 0-8 Mid-American) led 21-7 at halftime on two touchdown passes by Brogan Roback and a 35-yard interception return by Kyle Rachwal.

But Central Michigan (7-5, 6-2) fired back after the break, scoring on a 63-yard touchdown pass from Cooper Rush to Ross on its first possession, and then Ross’ 3-yard run — his second of the game — tied it at 21

Massachusetts 31, Buffalo 26

Freshman Marquis Young rushed for 240 yards and three first-half touchdowns and UMass held on to defeat host Buffalo.

Young, who had 215 yards at halftime, had runs of 6 and 47 yards for an early 14-0 lead and a 1-yard plunge later.
