Bungling Bengals implode against Pittsburgh

Chris Boswell booted a last-gasp field goal as the Pittsburgh Steelers punished the undisciplined Cincinnati Bengals en route to snatching an 18-16 victory between the bitter AFC rivals in Saturday's wild card game.

The Bengals appeared to be on the brink of a dramatic comeback win at home after overturning a 15-0 deficit in the fourth quarter to inch into a 16-15 lead with less than two minutes remaining.

But with victory beckoning, the Bengals imploded.
