NORMAN — Tailback Adrian Peterson will miss the rest of the regular season with a broken left collarbone, coach Bob Stoops announced after OU’s 34-9 victory over Iowa State.
Peterson suffered the injury when he dove into the end zone at the end of a 53-yard touchdown run with 6:35 left to play.
Stoops said early reports indicate that the earliest Peterson could return would be for a potential OU bowl game. Peterson will not need to undergo surgery, but a broken clavicle usually takes 6-8 weeks to heal.
"Just diving into the end zone and when he landed, he landed wrong," Stoops said. "At this point it looks like the best thing, the earliest he would be ready to play, would be a bowl game."
Oklahoma was well in control of the game when the injury happened.
Ahead 27-9, the Sooners forced Iowa State to punt, taking over at their own 47-yard line. On first-and-10, quarterback Paul Thompson handed off to Peterson, who squirted off the left tackle and through a gaping hole. Peterson cut back to the middle, juked two Iowa State defenders and headed toward the endzone.
As he approached the 10-yard line, Cyclone cornerback Chris Singleton dove at Peterson’s ankle, tripping him up slightly. Peterson maintained his footing long enough to dive into the endzone. But he landed hard on his left shoulder.
Peterson didn’t seem to be injured as he left the field after the play. By the time Oklahoma regained possession, the game was in garbage time. Allen Patrick played OU’s final series.
Peterson had 130 yards and a touchdown on 25 carries before the long run. He finished with 228 total yards and two scores with his father watching from the stands for the first time.
Nelson Peterson was released from an Oklahoma City halfway house nine days ago. He was in jail for nearly eight years on a federal money laundering conviction and missed his son's high school career at Palestine, Texas and all of Adrian's first two seasons at OU.
Peterson entered the game as the nation’s fourth-leading rusher and one of the leading candidates for the Heisman Trophy.
