Matt Barkley out for Sun Bowl; Max Wittek to start for Southern Cal USC Trojans quarterback Matt Barkley passes against the Washington Huskies defense at CenturyLink Field in Seattle, Washington October 13 2012. Barkley completed10 of 20 passes for 167 yards, one touchdown and one interception in the 11th ranked Trojans win over the Huskies 24-14. LOS ANGELES, Dec. 27 (UPI) -- Southern California quarterback Matt Barkley will miss the Trojans' Sun Bowl appearance because of a shoulder injury, Coach Lane Kiffin said Thursday. Barkley, a senior, was injured during USC's 38-28 loss to UCLA Nov. 17. He missed the Trojans' final regular-season game against Notre Dame, in which the No. 1-ranked Fighting Irish wrapped up a perfect regular season with a 22-13 win. Freshman Max Wittek replaced Barkley against Notre Dame and Kiffin said Wittek would start at quarterback in the Sun Bowl Monday against Georgia Tech. "I've worked as hard as I could to get back for this game and nature is not allowing it," Barkley said Thursday. Barkley is considered one of the top quarterback prospects heading into the 2013 NFL draft.
