NORMAN, Okla. (AP) — Oklahoma quarterback John Mateer had what some might consider an early Heisman Trophy moment when he scored the go-ahead touchdown against Auburn on a dramatic 9-yard run late in a 24-17 win. Unknown at the time, the hand he carried the ball with on that play –- the right hand he uses to throw — was injured badly enough in the first quarter to require surgery. Mateer tweeted Thursday that the procedure was successful, and the team expects him to return this season.
