MISSOULA, Mont. (AP) - Joey Counts scored on a 1-yard run on fourth-and-goal with 2 seconds left to give Montana a 38-35 victory over four-time defending FCS champion North Dakota State on Saturday.

Playing their first game under coach Bob Stitt, the Grizzlies rallied to stun the Bison in hazy conditions at jam-packed Washington-Grizzly Stadium.

Despite smoke from forest fires filling Hellgate Canyon, a stadium-record 26,472 fans showed up for the Football Championship Subdivision showdown.

Montana tied it at 28 in the third quarter on Gustafson's 62-yard pass to Ellis Henderson. The Bison took the lead on King Frazier's 7-yard scoring run with 10:37 left in the game.
