Troy Polamalu likely has concussion

Steelers HC Mike Tomlin said after the Sunday night win over Kansas City that S Troy Polamalu was experiencing "concussion-like symptoms." Polamalu left the Week 6 game early with a head injury that may have been a concussion, but he didn't miss any game time thereafter. The hard-hitting safety does have other previous concussions in his past, though. He'll obviously have to pass the mandated tests to play the Bengals in Week 13. IDP owners shouldn't count on that happening come waiver time. Ryan Mundy stepped in on Sunday night and finished with a team-high 10 tackles (7 solo) and an INT.
