MISSOULA, Mont. (AP) Chad Chalich threw six of his program-record seven TD passes in the first half, Keenan Curran tied a Montana record with four touchdown catches, and the Grizzlies beat Idaho State 62-44 on Saturday night.

Chalich overtook Jordan Johnson (2011), Brian Ah Yat (1998) and Dave Dickenson (1995) in the Montana record book with his seventh TD pass - a 6-yard strike to Curran that made it 55-31 with 10:49 left in the game.

Chalich, who found out he would be starting shortly before game time, finished with 388 yards passing and a 1-yard TD run early in the fourth quarter.

The Grizzlies (6-3, 3-3 Big Sky) led 41-31 at the break and pulled away as Idaho State (2-6, 1-4) struggled without starting quarterback Tanner Gueller, who left the game at halftime due to an injury. Trae Pilster and Tom Jewell handled the Bengals' QB duties in the second half.
