After a hard-fought road game, the Steelers traveled to Cincinnati to take on the Bengals. The Bengals started off the scoring in the first quarter when Randy Bullock kicked a 23-yard field goal for a 3-0 lead. The Steelers tied it up when Chris Boswell nailed a 45-yard field goal, leaving the score at 3-3, but the Bengals regained the lead late in the first quarter on Andy Dalton's 1-yard touchdown run to make the score 10-3. In the second quarter, the Bengals moved up by double digits as Jeremy Hill ran for a 4-yard touchdown to make it 17-3. The Steelers drew closer as Boswell made another field goal to make it 17-6, but Bullock put the Bengals back up by two touchdowns with a 23-yard field goal to make it 20-6. The Steelers closed the first half out with their third field goal of the game, as Boswell kicked a 49-yard effort to make the halftime score 20-9. Those three points would be the first three of 15 straight as they would shut out the Bengals in the second half, starting with field goals from 40 and 49 yards out to reduce the deficit to 20-15. In the fourth quarter, the Steelers moved even closer when Boswell kicked his sixth field goal of the game from 30 yards out to make it 20-18. They completed the comeback attempt when Ben Roethlisberger found Eli Rogers on a 24-yard touchdown pass with 7:29 remaining; however, the two-point conversion was unsuccessful, which made the score 24-20, which would end up being the final score. With the win, the Steelers improved to 9-5. The team also won five games in a row for the first time since 2009. The Steelers finished the season 5-3 away from home.
