According to Matt Maiocco of the Press Democrat, nose tackle Aubrayo Franklin will be out for four weeks with a right calf injury.

Matt Barrows of the Sacramento Bee reports that Isaac Sopoaga will take his place in the lineup with Ron Fields also filling in. While Atiyyah Ellison, who was inactive the first nine weeks, will get a long look in practice, Ray McDonald will probably be active on Sunday against the Rams.
