Buckeyes quarterback Terrelle Pryor will undergo surgery Friday afternoon to stabilize a ligament in his right foot. Pryor suffered the injury at the end of Tuesday's Allstate Sugar Bowl win against Arkansas. The injury was sustained on a quarterback sneak late in the fourth quarter. Pryor said after the Sugar Bowl that he's not ready for the NFL draft and will honor his pledge to coach Jim Tressel to return for his senior season. "I've got a lot of learning and better decision-making I have to make on and off the field," Pryor said. "Off the field, I need to grow up a little bit more, mature as well. I just have a lot of growing up to do."
