MISSOULA, Mont. (AP) -- Ben Davis kicked almost as many field goals Saturday as Montana committed turnovers, but his fourth one spelled the difference in a 33-30 Vandal victory over the Grizzlies.

His final kick came with two seconds to play, breaking a 30-30 tie and leaving the turnover-prone Grizzlies wondering how this could be.

"It's not easy coming into our place and stealing away a game," said Montana coach Mick Dennehy.

"We ended up having to work very, very hard for the points we got," Dennehy said. "They didn't have to work very hard" and that was the difference, he said.

Montana turned the ball over five times, losing three fumbles and two pass interceptions. Idaho lost no fumbles and had just one interception.

"We played well enough to win most games," Dennehy said. "But we've got to be a little more conscientious of doing the little things well. We've got to keep the (ball) wrapped up when we get into traffic."

Idaho coach Chris Tormey said he had a feeling the game would be won in the fourth quarter. "It was tied at halftime and the game could have gone either way."

The game was the first between the teams since 1995 when Idaho (4-1 Big West Conference, 7-3 overall) left the Big Sky Conference for Division I-A.

Montana defensive tackle Tyler Martin said the Idaho offensive line wasn't the best the Grizzlies have faced this season, but "they got it done in the end."

Running back Yohance Humphery, who committed two fumbles, said the Grizzlies were pumped coming out for the second half. "We thought we could play with these guys."
