MISSOULA, Mont. (AP) -- Josh Swogger passed for 231 yards Saturday, including a 54-yard touchdown pass to Eric Allen midway through the third quarter, in Montana's 13-7 victory over rival Montana State.
Montana (10-1, 8-0 Big Sky), ranked second in NCAA Division I-AA, won its 10th straight game, the Big Sky Conference championship and the league's automatic playoff berth. The pairings will be announced Sunday.
No. 15 Montana State (7-4, 6-2) saw its six-game winning streak and likely its playoff hopes end.
The Bobcats took a 7-3 lead on a 5-yard TD run by Aaron Mason with 5:07 left in the first quarter of the hard-hitting game. The scoring play was set up by a 43-yard pass from Jack Rolovich to Josh Lewis.
The second quarter featured three fumbles, a blocked field goal, a shanked punt and an interception returned 28 yards to the MSU 27 by Quinton Jackson.
On a fourth down from the 2 with less than 20 seconds left in the half, Montana went for a touchdown and came up empty.
Dan Carpenter, who kicked a 37-yard field goal in the first quarter, added a 42-yarder with 6:53 remaining for the final score.
MSU drove to the UM 19 with two minutes left, but Craig Mettler and Kerry Mullan sacked Cory Carpenter on fourth down.
Swogger completed just 17-of-41 passes and was intercepted twice. Allen caught five passes for 103 yards.
MSU starting quarterback Jack Rolovich completed 14 of 28 passes for 125 yards and also threw two interceptions. Carpenter was 2-of-6 for 18 yards and an interception. Lewis caught three passes for 57 yards.
Thomas Brooks-Fletcher rushed 11 times for 58 yards for Montana while Aaron Mason had 19 carries for 44 yards for the Bobcats.
