Sam Horn Injury: Out 'an extended period of time'

Horn (ankle) is out for "an extended period of time," with no specific timetable at the moment, per Calum McAndrew of the Columbia Tribune.

Horn was deemed out indefinitely after undergoing an MRI, and while there's no clear timetable for his return, an "extended period of time" sounds like Missouri is bracing for its quarterback to miss multiple weeks, perhaps months. He battled Beau Priblua for the starting gig all offseason, and now Pribula will take the reins as Missouri's full-time starting signal-caller.
