The nation's leading rusher comes to the Kibbie Dome on Saturday when Fresno State plays surprising Idaho.
Ryan Mathews is averaging 164 yards per game, and will pose a major challenge for a porous Idaho rush defense.
The Vandals hope to limit Mathews' big gains, and come up with a few big plays of their own in seeking their eighth win of the season.
Idaho (7-2, 4-1 WAC) is enjoying the nation's biggest turnaround, and has already won five more games than last year.
Fresno State (5-3, 4-1) has won four straight games after a slow start that included losses to Boise State and Cincinnati.
