PROVO, Utah -- Jake Heaps threw for 185 yards and two touchdowns after coming off the bench in the first quarter to propel Brigham Young to a 42-7 victory over Idaho on Saturday.
Heaps, a sophomore who lost his starting job early this season, entered when Riley Nelson suffered a broken rib on a play on which he threw a 32-yard touchdown pass to Cody Hoffman. Nelson did not return, and finished with 56 yards passing.
There was no immediate word on how long Nelson would be out, but Heaps seems likely to return to the starting role.
"(Heaps) was hungry," coach Bronco Mendenhall said. "Not to say he wasn't hungry to lead the team before, but he looked poised to me and he looked confident, like he was anxious to re-establish himself."
Heaps said, "It was just good to get out there, throw and be with the guys."
Hoffman had two touchdown catches and 114 yards on six receptions for the Cougars (7-3). Michael Alisa rushed for 99 yards and a touchdown.
Idaho (2-8) allowed the Cougars 505 yards of offense.
Bryan Kariya added touchdown runs of 17 and 1 yards, and Heaps threw a 21-yard touchdown pass to Hoffman with 13 seconds left in the first half to make it 28-0.
■ UNR 42, Hawaii 28 -- At Reno, Cody Fajardo threw for three touchdowns and ran for a score as the Wolf Pack (6-3, 4-0 Western Athletic Conference) beat the Warriors (5-5, 3-3).
Fajardo threw two TDs to Rishard Matthews, who had 118 yards for his fifth 100-yard receiving game of the season. The Wolf Pack rolled up 531 yards.
Hawaii quarterback Bryant Moniz, the WAC's leading passer and preseason player of the year, suffered a right leg injury with 6:50 to play in the first quarter and did not return. Backup Shane Austin completed 17 of 38 passes for 246 yards and a touchdown, but had three interceptions.
