Fresno State running back Marteze Waller was off to a strong start Saturday night in the Bulldogs' 38-14 victory over UNLV, averaging 5.9 yards on 11 rushes and catching three passes for another 16 yards in the first half.
But the sophomore went down and out in the fourth quarter with a right foot injury that could sideline him for a while, making it a tough week for Bulldogs running backs.
"He's going to have a MRI on Monday," coach Tim DeRuyter said. "X-Rays were negative, and we'll find out then. They've ruled out Lisfranc, but he has some sort of a foot issue. I don't know if it's a bruise or strain or what, but we'll find out on Monday."
A Lisfranc injury is a fracture or dislocation in the mid-foot region.
Waller, who made his first career start against the Rebels, had been splitting reps with junior Josh Quezada, but the position group will thin considerably if he were to miss any time. Fresno State already lost Dontel James for the season Wednesday, after he had surgery to repair a toe injury.
Once five deep and rotating running backs in a committee, the Bulldogs are down to three healthy backs in Quezada, junior Malique Micenheimer and redshirt freshman T.J. Thomas.
Quezada rushed the ball 12 times for 75 yards against UNLV and caught five passes for another 26. Micenheimer had six plays for 18 yards and Thomas four plays for 9 yards.
"Hopefully everything will come out clean on Monday -- I thought he really ran the ball well," DeRuyter said of Waller. "But that's why you have to have multiple running backs."
