PITTSBURGH (AP) — Left for dead in mid-December, the Pittsburgh Steelers are heading back to the playoffs anyway. Pittsburgh clinched a wild-card spot when Tennessee upset Jacksonville, giving the Steelers a playoff berth that seemed unlikely following a three-game skid that included losses to lowly Arizona and New England. Pittsburgh bounced back to finish the season with a three-game winning streak, culminating in a victory over rival Baltimore in Week 18. The Steelers will play at AFC East champion Buffalo in the wild-card round Sunday at 1 p.m.
