In Denver, reserve receiver Darrell Jackson was limited in practice with a calf injury. He has missed the past three games. Defensive end John Engelberger was limited in practice after sitting out Wednesday due to a knee injury.

Defensive tackle Dewayne Robertson has practiced fully both days this week. He didn't play last week because of a nagging knee injury. It looks like Robertson is on target to play Sunday against visiting Tampa Bay.

Fullback Mike Tolbert was limited with an ankle injury. Defensive tackle Jamal Williams was limited Thursday after not practicing Wednesday. He has a lingering knee injury that requires him to rest often during the practice week. Tight end Antonio Gates and guard Mike Goff practiced fully Thursday after sitting out Wednesday with injuries.
