Manningham moved to I.R., Jerod-Eddie promoted to 53-man roster

The 49ers just announced they’ve moved Mario Manningham to the injured reserve and replaced him on the 53-man roster with rookie undrafted defensive tackle, Tony Jerod-Eddie.

The 49ers could be missing as many as three defensive tackles against the Cardinals on Sunday. Justin Smith has a partially torn triceps, Will Tukuafu has an injured neck and Demarcus Dobbs is out for the year with a knee injury.

Jerod-Eddie (6-5, 301 pounds) has a chance to play against the Cardinals, because the 49ers need a backup five-technique defensive end who can sub in for Ray McDonald or Ricky Jean Francois if either player gets tired.
