In addition to right guard Marshal Yanda and inside linebacker Dannell Ellerbe being absent, strong safety Bernard Pollard was missing during the portion of Thursday's practice open to the media.
Pollard was not listed on Wednesday's injury report, which could be interpreted as a good sign. But the reason for his absence won't be known until later.
Yanda is dealing with a bruised rib and thigh, while Ellerbe wore sunglasses Wednesday as a result of post-concussion symptoms.
Defensive tackle Arthur Jones, who did not practice Wednesday because of an illness, returned to Thursday's session. Defensive end Cory Redding (right ankle), cornerback Cary Williams (post-concussion symptoms) and kicker Billy Cundiff (left calf) – all of whom were limited Wednesday – were present and active.
