NORMAN, Okla. (AP) - Heisman Trophy hopeful Adrian Peterson broke his collarbone on a dive into the end zone Saturday, and the Oklahoma star running back will miss the rest of the regular season.
Peterson was injured on his last carry of the game - a 53-yard scoring run with about 6:40 remaining that completed the 23rd-ranked Sooners' 34-9 win over Iowa State.
Peterson ran for 183 yards and two touchdowns.
Peterson, a junior, who has 1,030 yards this season and entered the weekend as the nation's fourth-leading rusher, was second in Heisman voting as a freshman. He was playing for the first time in years before his father, who had spent about eight years in federal prison for money laundering.
