FOXBOROUGH, Mass. >> Army linebacker Kalib Fortner scored on a fourth-quarter strip sack and then stuffed quarterback Tai Lavatai six inches from the goal line with 3 seconds left to help the Black Knights beat Navy 17-11 on Saturday and win the 124th meeting of the nation’s oldest service academies.

After falling behind 17-3, Lavatai led the Midshipmen to one touchdown to make it a one-score game and then drove them to the Army 6. With no timeouts and about 30 seconds left, Lavatai threw two incompletions before hitting Alex Tecza, who was tackled in bounds at the 2.

With no timeouts — and no opportunity to spike the ball on fourth down — Navy scrambled to line up and managed to get the play off. Lavatai surged forward as his whole team pushed, ahead of him and behind, but Army held its ground.

The play was whistled dead and the replay confirmed that the ball never crossed the goal line. To kill the remaining 3 seconds, Army quarterback Bryson Daily took a shotgun snap, hesitated, and stepped out of the end zone for an intentional safety.

Cadets began to storm the field before being sent back for another review to see if time had expired. The confirmation from the booth set off another wave of Army fans onto the field.

Bryson Daily ran for 84 yards and threw Army’s first touchdown pass against Navy since 2015 to help the Black Knights claim bragging rights for the second straight year and the sixth time in eight tries.

Kanye Udoh ran for 88 yards for Army, which also claimed the Commander-in-Chief’s Trophy that goes to the team with the best record in head-to-head matchups against other service academies. The Black Knights upset then-No. 17 Air Force last month.

North Dakota State 45, South Dakota 17

Cam Miller had a touchdown by pass and run, Cole Payton rushed for two scores and North Dakota State rolled over South Dakota in the quarterfinals of the FCS playoffs in Vermillion, S.D.

The Bison (11-3), who have won nine of the past 11 FCS championships, will travel to second-seeded Montana for a semifinal matchup.

The third-seeded Coyotes (10-3) won 24-19 at NDSU in September to snap a six-game losing streak to the Bison but were down 21-0 after the first quarter Saturday following an 82-yard punt return by Jayden Price. Miller ran 9 yards to cap NDSU’s opening 75-yard drive and running quarterback Payton rushed for a 43-yard score.

Miller added a 4-yard TD pass to finish an 81-yard drive, and Payton ran 17 yards for a 35-3 halftime lead.

Miller was 13 of 15 passing for 210 yards, Payton had 65 yards on six carries and TaMerik Williams added 58 yards rushing and another TD.

South Dakota State 23, Villanova 12

Isaiah Davis ran for 192 yards, including a 66-yard touchdown run, and top-seeded South Dakota State, the defending national champions, defeated eighth-seeded Villanova in an FCS quarterfinal in Brookings, S.D.

That touchdown early in the fourth quarter was the only offensive score by either team going into the wind, which gusted up to 45 miles an hour.

The Jackrabbits (13-0), who won their 27th straight game, are home against the winner of No. 4 Idaho and No. 5 Albany in the semifinals next weekend.
