MISSOULA, Mont. (AP) The Montana Grizzlies rode three touchdowns from freshman Jeremy Calhoun to a big first-half lead on the way to a 57-16 victory over Eastern Washington in a key Big Sky Conference football game Saturday.

Calhoun's touchdown runs covered 3, 1 and 3 yards, and the Grizzlies (6-4, 5-2) used a fumble return by Herbert Gamboa and an interception return by JR Nelson to push out to a 50-9 lead midway through the third quarter.

The victory snapped Montana's four-game losing streak to EWU, and kept the Grizzlies' slim playoff hopes alive.
