LAS VEGAS -- Armani Rogers accounted for three touchdowns, Charles Williams ran for three more, and UNLV cruised to a 56-23 win over Southern Utah on Saturday night in the season opener for both teams.

Rogers was 11-of-17 passing for 144 yards and a score and added 11 carries for 114 yards and two touchdowns and Williams finished with 143 yards rushing and three TDs.

Williams scored on runs of 22 and 8 yards to make it 14-0 before Chris Helbig led Southern Utah on an 11-play, 77-yard drive capped by his 2-yard TD run with 9:34 left in the second quarter.
