Troy Polamalu won’t play Sunday in Cincinnati. He probably won’t play next week or the week after that, not with a torn calf muscle that has turned his right leg a hideous shade of purple and red. But the reason he’s hurting isn’t just because of an injury that usually takes up to six weeks to heal. It’s because the Steelers (2-3) need him badly after losing each of their first three road games, and he won’t be out there Sunday night in Cincinnati to help a struggling defense. “That’s why they (NFL teams) pay the more talented players big money, to keep them on field,†Polamalu said Wednesday. “Obviously, you want your starters and your more experienced players out there.†The best-case scenario for Polamalu’s return, according to teammates, is the second half of the season.
