The Browns entered into their divisional rivalry game with the Pittsburgh Steelers having lost 19 of their last 22 meetings and 11 straight games at Heinz Field. Neither team's designated starting quarterback would start the game as Josh McCown had a rib injury and Stelers' QB Ben Roethlisberger had an foot injury. Pittsbugh QB Landry Jones would leave the game in the first quarter, forcing Roethlisberger into the game. Leading 6-3 after the 1st quarter, the Steelers would take control of the game in the 2nd quarter, scoring two touchdowns and taking a 21-3 lead into halftime. Steelers K Chris Boswell added a field goal in the third quarter, followed up by a Johnny Manziel touchdown pass to Gary Barnidge early in the 4th quarter to cut the Pittsburgh lead to 24-9, but a late Steelers touchdown gave them a 30-9 lead, which would end up being the final. Coming off the bench, Roethlisberger passed for 379 yards and three touchdowns, two of which went to WR Antonio Brown who led the Steelers with 139 yards. In the loss, Manziel passed for a career-high 372 yards with a touchdown, but he threw a key interception in the red zone. The Steelers defense sacked Manziel six times. With the loss, the Browns entered their bye week at 2-8 and had sole possession of the NFL's worst record.
