Polamalu missed four of Steelers’ past five games because of a ligament tear and injured the same knee again on his first returning game: last Sunday’s 18-12 loss to the Cincinnati Bengals. And it is very likely that he will miss more than one game after being injured again, but perhaps less than four because the latest injury to a different ligament seems less serious than the previous one.
Along with Polamalu, defensive end Travis Kirscheke has also been rule out of this Sunday’s game and it will be the third consecutive he will miss since tearing his left calf muscle. Originally filling in for Aaron Smith who is out for season with a torn right rotator cuff, Kirschke will be replaced by Nick Eason this Sunday. And Tyrone Carter will put on his Steelers jersey and start in replacing Polamalu.
