The 4th quarter however, was all Bengals as Andy Dalton and Tyler Eifert connected on a 1-yard touchdown pass making the score 30-14 not long before Dalton found Marvin Jones on a 13-yard pass making the score 30-20, but the 2-point conversion failed as the Steelers would eventually win the game with that score as the final sending them to 6-8.
