Stephen F. Austin scored 21 points in the final nine minutes to upset third-ranked Montana State, 52-38, Saturday night.
Gus Johnson's 5-yard touchdown run with 5:01 remaining put SFA (2-2) ahead to stay, 45-38.

Earlier, SFA tied the game at 38-38 on Joshawa West's 13-yard run with 8:45 left.
"We ran into a hot offense tonight," Montana State coach Rob Ash said. "Explosive offenses can be like good-shooting basketball teams, they get on a roll and it's really hard to stop. I thought we played very well in the third quarter, we stopped them from scoring and got the only points of the quarter. But they answered in the fourth quarter, and credit's to them."
