PITTSBURGH -- Steelers quarterback Ben Roethlisberger is listed as probable for the Steelers' game against the Oakland Raiders on Sunday, while safety Troy Polamalu will be sidelined with a knee injury that has already caused him to miss two straight games.
Roethlisberger missed the team's last game against the Baltimore Ravens after experiencing exercise-induced headaches following a concussion he suffered against the Kansas City Chiefs on Nov. 22.
Polamalu's latest injury -- a PCL strain -- is to a different ligament than the one he tore in the season opener and caused him to miss the Steelers' second through fifth games.
Defensive end Travis Kirschke is doubtful and will likely sit out his third consecutive game with a torn left calf muscle. He had been filling in for Aaron Smith, who is out for the season with a torn right rotator cuff.
Nick Eason looks to start again at left defensive end. Tyrone Carter will start at safety.
Chris Kemoeatu was also listed as probable on Friday and is expected to resume his role as the team's starting left guard.
Kemoeatu suffered an MCL tear against the Chiefs and did not play against the Baltimore Ravens on Sunday.
