CINCINNATI (AP) — Andy Dalton has barely been touched in the last three games. The Bengals have won all three.

There's a direct correlation that's going to be in the front of their minds on Sunday night in Pittsburgh as Cincinnati closes in on the AFC North title. When Dalton can stay upright, things usually work out all right. The Bengals (9-4) haven't allowed a sack in any of the last three games, matching their franchise record for protecting the quarterback. They also went three games without a sack in 1977, 2007 and 2010, according to STATS LLC. And they've done it with an offensive line that's been repeatedly reconfigured because of injuries.
