Texas A&M has lost senior defensive tackle Kirby Ennis for the season to a knee injury, and coach Kevin Sumlin said Ennis will have surgery.
Ennis, a redshirt senior, was injured Sept. 28 against Arkansas. Ennis will have surgery to repair the torn anterior cruciate ligament in his left knee.
Ennis, who was suspended for the opener for violating team rules, appeared in four games and had six tackles. He started 11 games last season and had a career-high 23 tackles, including two for losses.
Sumlin said Ennis' spot in the starting lineup would be filled by Isaiah Golden, a true freshman.
The ninth-ranked Aggies (4-1, 1-1 SEC) play at Mississippi (3-2, 1-2) on Saturday.
