It looks like Ryan Mathews sustained some sort of injury on the long run that ended at the 1-yard line. Mathews was blindsided by a defender he didn't see coming from his left side, and waved to the sideline for a replacement as he jogged gingerly off the field. Lonyae Miller then punched in for the touchdown in the third quarter.

This is total speculation, but it appears to be some sort of rib injury, because he's been holding his left side ever since coming off the field. He sat on the bench for quite a while being looked at by trainers, and then was worked on while lying on his back on a wooden bench on the Bulldogs sideline. Now he's walking around on the sideline, holding his helmet and looking like he might try to come back.

He really looks sore, so this might just be posturing so Utah State thinks he's coming back. He's had the headset on a couple times, talking to the coaches up in the booth. He's also done some quick steps and cuts, testing it out, so maybe he is coming back.

You'd hate to see the national rushing leader get more seriously injured, but the Bulldogs really really need him right now.
