Brad Sorensen threw four touchdown passes for Southern Utah (0-2), an FCS school from the Big Sky Conference which was playing a Pac-12 school for the first time.

The Thunderbirds took the opening kickoff in the second half and went 75 yards in 12 plays, capped by a 5-yard touchdown pass from Sorensen to Henna Brown.

Allen's TD reception from quarterback Zach Maynard extended the lead to 27-17 on the first play of the fourth quarter, and the Bears got a 61-yard interception return for a touchdown by Marc Anthony before Allen sealed the game when he returned a punt 69 yards for a score after fumbling the kick.

Sorensen completed 31 of 45 passes for 292 yards.
