Barnett (hamstring) is expected to be out for multiple weeks, Pete Thamel of ESPN reports.
Analysis:Previously undisclosed, Barnett's injury involves one of his hamstrings, which adds up considering that he left Central Florida's latest game limping after attempting 31 passes at Pittsburgh. Though the quarterback's return timetable is uncertain, his publicized diagnosis indicates that he will be out for at least one game, the Knights' Week 3 matchup against Georgia State. Keyone Jenkins replaced Barnett late in Week 2, and the expectation is that the former starts under center against GA State next Saturday.
