Samaje Perine, who rushed for a Big 12 Conference best 1,713 yards last year, has gotten off to a slow start this season.
Saturday against Tulsa, it appeared Perine got hurt. He left the field, after fumbling in the second quarter and headed to the locker room holding his wrist.
Perine came into the game averaging just 3.3 yards per carry on 34 attempts through two games.
