Steelers defensive end Brett Keisel is expected to play this weekend at Buffalo after missing all but a few plays of the last five games with a sore hamstring, coach Mike Tomlin said Tuesday.
Rookie wide receiver Antonio Brown (swollen knee) will be limited in practice and might not play Sunday for the Steelers. Tight end Matt Spaeth's status is uncertain because of a concussion he sustained during last Sunday's game against the Oakland Raiders.
Safety Will Allen has been cleared to practice after sitting out two games with a concussion. Safety Troy Polamalu might be limited again in practice because of an Achilles' injury, as he was last Sunday, but Tomlin said he expects his defensive star to play.
Ramon Foster remains at right guard after being promoted ahead of Trai Essex and Doug Legursky before the 35-3 victory over the Raiders.
