NORMAN, Okla. - Oklahoma starting running backs Samaje Perine and Joe Mixon fumbled last Saturday in Oklahoma's win over Tulsa.
And it appeared the two paid for it on Monday.
Perine and Mixon were seen at practice doing push-ups every 5 yards from endzone to endzone in what clearly looked like a drill to let the players know their fumbles weren't forgotten.
OU has fumbled four times this year through three games, losing three of them.
