After winning at home, the Steelers traveled to Cincinnati for Game 2 against the Bengals. Before the game started there were an altercation between the two teams during warmups. Vince Williams and Vontaze Burfict were in the center of the scuffle.

QB Andy Dalton would be knocked out of the game so backup QB AJ McCarron came in and threw his first career TD pass to A. J. Green from 66 yards out to make the score 13-7.  Boswell, however, wrapped up the scoring of the first half with another 47 yard field goal for a 16-7 lead at halftime.  In the third quarter, the Steelers went back to work as William Gay picked off AJ McCarron and returned it 23 yards for a TD for a 23-7 game.  Mike Nugent would kick a 46-yard field goal to make it 23-10.  The Steelers went back to work in the fourth quarter when Boswell kicked a 31-yard field goal for a 26-10 game.  The Bengals responded with Nugent kicking a 27-yard field goal for a 26-13 game.
