Texas A&M's struggling defense was dealt a blow when news surfaced on Tuesday that starting defensive tackle Kirby Ennis will miss the remainder of the season because of a knee injury.
Ennis, a 6-foot-4, 310-pound senior, tore the anterior cruciate ligament in his left knee against Arkansas on Sept. 28 and will have season-ending surgery, head coach Kevin Sumlin said on Tuesday.
The Aggies' run defense is last in the SEC, allowing 214.8 yards per game. The unit has struggled as a result of the combination of shifting personnel, as well as youth and inexperience on the depth chart. Now the Aggies must turn to a true freshman to take Ennis' place: Carthage (Texas) High School product Isaiah Golden.
Golden, who has appeared in four of the Aggies' five games this season, will make his first career start Saturday at Ole Miss. The ESPN 300 recruit, who signed with the Aggies in February, has 11 tackles and two tackles for loss to his credit so far this season.
He'll start next to sophomore Alonzo Williams, who has started all five games at the other defensive tackle position. True freshman Hardreck Walker and junior Ivan Robinson will also be a part of the defensive tackle rotation moving forward.
Ennis is a four-year letterman who started in 11 games in 2012. He appeared in four games this season, recording six tackles, a half tackle for loss and a quarterback hurry.
