LAS VEGAS (KLAS) — Doug Brumfield threw four first-half touchdown passes, including a pair to Ricky White, as UNLV opened its season Saturday with a 52-21 rout of Idaho State at Allegiant Stadium.

Brumfield finished 21-for-25 passing for 356 yards. His scoring strikes were for 72 and 19 yards to White, 14 yards to Kyle Williams and 7 yards to Aidan Robbins.

The Rebels scored 35 points in the second quarter and led 45-7 at halftime.

White caught eight passes for 182 yards, all in the first half. His performance ranks 11th for receiving yards in school history.

Brumfield was in a fight for the starting job with sophomore transfer Harrison Bailey, and coach Marcus Arroyo had declined to name a starter leading into the game.

Neither Brumfield nor White played in the second half.

The Rebels totaled 552 yards, including 405 passing.

“I really enjoyed the efficiency of the first half, the way we moved the ball around and the way we moved,” Arroyo said. “Did a nice job on defense stopping the run game … I thought we did a good job of taking care of football. Zero turnovers. I think that is a big deal, especially for week one.”

UNLV’s 45 points in the opening half ranked as the second-highest production in a half in program history. The Rebels had 52 first-half points in 2015 against Idaho State, winning 80-8.

The victory gives the Rebels a 25-30 record in season openers, including 20-10 when the season’s first game is at home.

UNLV is off next weekend and returns to action Sept. 12, visiting Pac-12 rival California.
