Tyler completed 22 of 33 passes for 183 yards and added 49 yards rushing, while Landen Measom had eight receptions for 57 yards and two touchdowns for Southern Utah (5-2, 3-1 Big Sky Conference).
Southern Utah used a nine-play, 80-yard drive to take the lead for good when, on fourth-and-2, Patrick Tyler hit Logan Parker for a 26-yard touchdown with 7:39 to go. A couple plays later, Jalen Russell intercepted a pass to set up a 12-yard scoring catch by Measom that made it 39-28 just 75 seconds later.
Eastern Washington (5-3, 4-1) committed four turnovers and had its five-game win streak snapped. Gage Gubrud had 246 yards passing and 64 yards rushing, but threw three interceptions.
The Eagles took a 14-0 lead on a 3-yard rushing touchdown by Sam McPherson in the first quarter and, after Jay Green's 1-yard scoring run and Parker's 2-point conversion run, Dre Dorton returned the ensuing kickoff 96 yards to make it 21-8 with 5:12 left in the first half. Felila had an 8-yard TD run before the half, Measom added an 8-yard scoring reception in the third and Manny Berz hit a 43-yard field goal to make it 25-21 going into the fourth.
On third-and-15, Gubrud hit Zach Eagle -- who, replay confirmed, dragged his back foot before stepping out of bounds -- for a 20-yard gain and, on the next play, Antoine Custer scored on a 2-yard run to give EWU a 28-25 lead with 11:32 left.
