AIR FORCE ACADEMY -- Senior Wes Cobb ran for a career-high 152 yards and a touchdown on 30 carries in place of injured Cody Getz and Air Force stymied Stefphon Jefferson in a 48-31 victory over Nevada on Friday night in the first meeting between the schools.

The Falcons (5-3, 4-1 Mountain West) snapped a four-game road winning streak by the Wolf Pack (6-3, 3-2) and held Jefferson to 93 yards -- 63 below his nation-leading average -- six days after surrendering a conference-record 338 yards to New Mexico's Kasey Carrier.

Jefferson came in as the nation's top rusher by a whopping 17 yards per game, but it was the Falcons running wild on this bitterly cold night, rushing for 461 yards, including 96 by Jon Lee, 76 by Ty MacArthur and 68 by quarterback Connor Dietz, who scored on a 1-yard run and also threw two long touchdown passes while going 6 for 7 for 139 yards.

The Falcons limited Johnson to 22 yards on nine first-half carries and took a 31-21 lead into the locker room after scoring on five of their six drives.

They turned the ball over on their first possession of the second half and Johnson made them pay with a 21-yard TD run following linebacker Dray Bell's recovery of Jon Lee's fumble at midfield.

Cobb, who topped his old career high of 83 yards set last year against Colorado State, restored the Falcons' 10-point cushion with a 1-yard TD run.

The Wolf Pack had to settle for Allen Hardison's short field goal after its drive stalled inside the Air Force 10, and his 26-yarder on the first snap of the fourth quarter made it 38-31.

Dietz's 1-yard keeper gave the Falcons a two-TD cushion, their largest of the game, with 9½ minutes left.
