After another close win, the Steelers stayed home for a game against the Patriots. The Pats scored first in the first quarter when Rex Burkhead ran for a 1-yard touchdown to make it 7-0. The Steelers tied the game up later on when Ben Roethlisberger found Eli Rogers on an 18-yard pass to make it 7-7. In the second quarter, the Steelers took the lead when Chris Boswell kicked a 51-yard field goal to make it 10-7. The Pats would tie it up again when Stephen Gostkowski kicked a 32-yard field goal to make it 10-10. The Steelers then moved ahead when Roethlisberger found Martavis Bryant on a 4-yard pass to make it 17-10 at halftime. In the third quarter, the Pats drew closer when Tom Brady found Brandin Cooks on a 4-yard pass to make it 17-16 (with a failed PAT). The Steelers then moved further ahead when Le'Veon Bell ran for a 3-yard touchdown to make it 24-16 following a Brady interception. In the fourth quarter, Gostkowski's 46-yard field goal made it 24-19. Dion Lewis then ran for an 8-yard touchdown (with a successful 2-point conversion) to make it 27-24.  The Steelers managed to make it deep into Patriots territory on the ensuing drive. However, an apparent touchdown pass to tight end Jesse James was controversially overturned after replay, and Roethlisberger was intercepted two plays later, sealing the win for the Pats. With their 8-game winning streak snapped, the Steelers fell to 11-3.
