Dison scored 18 points on 8-of-12 shooting. Montana State (7-6, 2-0 Big Sky) has won five of its last six.
Northern Arizona's Kris Yanku made two free throws and a 3-pointer to tie the game at 64 with 1:55 remaining. Davis then missed a layup, grabbed the rebound, only to miss his put-back. Yanku stole Paul Egwuonwu's rebound and passed to Quinton Upshur, whose layup gave the Lumberjacks a 66-64 lead with 50 seconds to play.
Davis answered with a jumper to tie the game at 66 with 32 seconds left. Following timeouts from both teams, Yanku's turnover led to Dison's game-winning layup.
