DAVIS, Calif. -- Steve Walker threw for 227 yards and three touchdowns in the first half as North Dakota State University upset No. 20 UC Davis 25-7 before a crowd of 6,720 at Toomey Field on Saturday, Nov. 13.

Running back Cinque Chapman ran 22 times for 107 yards for the Bison (8-3), who finished with 410 total offensive yards. NDSU had lost the last two meetings to UC Davis, 23-14 in Fargo last season and 35-7 at Davis in 2002.

Jon Grant was 23-of-34 for 240 yards and Daniel Fells caught 5 passes for 90 for UC Davis (6-3), which failed to clinch a share of the first-ever Great West Football Conference championship. Cal Poly defeated Northern Colorado 31-0 on Saturday night to claim the conference title.

North Dakota State scored on two consecutive fourth down situations in the first period as Walker hit Travis White and Charles Wiest for 24 and 29 yards touchdown passes, respectively. The Bison, controlling time of possession for 12 minutes and 16 seconds on offense, racked up 170 yards to the Aggies' 5 yards in the first quarter.

North Dakota State caused UC Davis problems with a swarming defense. Jayd Kittelson led the defense with 12 tackles including one tackle for a loss. The Bison had five tackles for a loss including sacks from Isaac Snell, Justin Frick, Isaac LaVant and Alvin Robinson. Robinson also had three pass breakups.

After Jon Grant was called for intentional grounding to give North Dakota a team safety in the second quarter, Walker hit Marques Johnson for a 50-yard score. The Aggies had a chance to score with five seconds left before the half, but failed on a pass attempt as time expired.

Walker, who completed 15-of-20 passes against UC Davis, finished the season 47 of 60 passes for 705 yards, 10 touchdowns and no interceptions.

Davis finally got on board with a 7-yard run by Nelson Doris in the fourth quarter. But the Bison's running game behind Chapman and Kyle Steffes kept the Aggies on the field for the remainder of the game. Steffes rushed 20 times for 75 yards and recorded his first 1,000 yard season -- finishing with 1,055 yards.

After kicking 50 consecutive extra points, North Dakota State place kicker Cory Vartanian finally missed in the second quarter. Vartanian did hit a 46-yard field goal in the third quarter to put NDSU ahead 25-0. It was the longest outdoor field goal of his career.
