TROY, Ala. -- Jordan Chunn returned after missing two games to rush for 113 yards and two touchdowns and Troy held off Idaho 24-21 on Thursday night.

Leading 17-14, Troy made a field goal with 4:53 remaining but the Trojans accepted a roughing the kicker penalty to make it fourth-and-1. Brandon Silvers picked up the first down on a sneak and Chunn scored from 7 yards out for a 10-point lead.

Idaho answered with an 81-yard drive, capped by Mason Petrino's 6-yard touchdown pass to David Ungerer with 23 seconds remaining. But Troy recovered the onside kick to seal it.

Chunn scored his 44th career rushing touchdown in the second quarter to tie it at 7 and Tyler Sumpter made a 40-yard field goal as time expired in the first half to give Troy (7-2, 4-1 Sun Belt) a 10-7 lead. In the third, Tevaris McCormick was left wide open along the right side for a 14-yard touchdown to make it 17-7.

Idaho's two third-quarter possessions ended on failed fourth-down attempts at Troy's 33 and 34. On its third drive of the second half, Kaden Elliss' 45-yard catch up the middle set up Alfonso Onunwor's second touchdown grab of the game to pull within 17-14.

Matt Linehan's play-action pass to Onunwor opened the scoring for Idaho (3-6, 2-3) late in the first quarter. Linehan was 23-of-34 passing for 282 yards and Onunwor made nine catches for 111 yards.
