Both No. 10 Texas A&M and Mississippi will start backup quarterbacks on Saturday when they meet after Aggies starter Trevor Knight and Rebels starter Chad Kelly both suffered serious injuries last week. The Aggies will go with Jake Hubenak, who threw for 222 yards with two touchdowns and an interception after taking over after Knight injured his shoulder in a loss to Mississippi State on Saturday that knocked Texas A&M out of the College Football Playoff top four.
