COLUMBUS, Ohio -- Ohio State quarterback Terrelle Pryor underwent surgery on Friday afternoon to repair an injury to his right foot. Posting on his Twitter account, Pryor deemed the surgery "successful."

Pryor was injured in the fourth quarter of the Buckeyes' 31-26 Sugar Bowl win over Arkansas on Tuesday. It was a quarterback sneak in which he has reaching for a first down. He left the game, but did return with a limp. The surgery stabilized some ligaments in the foot.

Pryor faces a five-game suspension at the beginning of the 2011 season for his role in selling Ohio State awards to a tattoo parlor owner. It is not known whether the junior will stay and serve the suspension or leave for the NFL draft.

But Pryor did say 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."
