SANTA CLARA -- The 49ers promoted undrafted rookie defensive lineman Tony Jerod-Eddie from the practice squad to take the roster spot vacated when the club placed wide recever Mario Manningham on injured reserve with torn knee ligaments.
The 49ers opted to place Jerod-Eddie on the 53-man roster because the 49ers have some depth issues on the defensive line with All-Pro defensive tackle Justin Smith likely out for Sunday's game against the Arizona Cardinals with a partially torn triceps tendon. The 49ers are holding out hope that Smith will be available for the playoffs.
Jerod-Eddie played 51 games with 38 starts at Texas A&M, where he recorded 148 tackles, seven sacks and 14.5 tackles for loss in his career. He was a second-team All-Big-12 selection as a senior.
Receivers Chad Hall and Ricardo Lockette will remain on the practice squad. The 49ers determined there was no reason to promote either player because they would not suit up with the 49ers already set to go with Michael Crabtree, Randy Moss, A.J. Jenkins and Ted Ginn at wide receiver.
