Chris Boswell kicked a field goal on the final play of the game to seal a stunning come-from-behind 23-20 NFL win for Pittsburgh over Cincinnati on Monday night.
The match sealer came shortly after Antonio Brown caught a six-yard touchdown pass and took a hit to the head while landing in the end zone.
Down 17-0 early, the Steelers (10-2) extended their best start since 2004 in a physical game with a couple of frightening injuries.
Brown's touchdown tied it at 20-20 with 3:51 to go, setting up Boswell's 38-yard field goal, his second straight winner in the closing seconds.
The Bengals (5-7) simply can't find a way to beat their Ohio River rivals, not even after getting off to the big early lead.
They've dropped six straight against Pittsburgh, including the Steelers' 18-16 playoff win at Paul Brown Stadium that included another Bengals meltdown.
Pittsburgh lost leading tackler Ryan Shazier to a back injury in the first quarter.
The linebacker was taken off the field on a cart and taken to a hospital for evaluation. Bengals linebacker Vontaze Burfict was carted off in the fourth quarter after JuJu Smith-Schuster levelled him with a high hit, then taunted him by walking over him.
Steelers coach Mike Tomlin did not have an update on Shazier's status after the game.
There were 11 personal fouls in another acrimonious rematch in their hard-edged series. The Bengals self-destructed with 13 penalties for 173 yards.
The AFC North-leading Steelers remain tied with New England for best record in the conference. They host the Patriots on December 17.
