After a huge win, the Steelers stayed home for a game against the Packers. They would score first in the first quarter when Ben Roethlisberger found Xavier Grimble on a 1-yard pass (with a failed PAT) to make it 6-0. The Packers scored 2 touchdowns to close out the first half. The first one followed an interception thrown by Roethlisberger when QB Brett Hundley found Randall Cobb on a 39-yard pass to make it 7-6. The Steelers' defense also stalled later on in the quarter when Hundley found Jamaal Williams on a 54-yard pass to make it 14-6 in favor of the Packers. In the second quarter, the Steelers managed to tie the game when Roethlisberger found Martavis Bryant on a 17-yard pass (with a successful 2-point conversion) to make the score 14-14 at halftime. In the third quarter, the Packers retook the lead when Hundley found Davante Adams on a 55-yard pass to make it 21-14. Later on, the Steelers tied it back up when Roethlisberger found Antonio Brown on a 1-yard pass to make it 21-21. The Steelers managed to take the lead when Roethlisberger and Brown hooked up again this time on a 33-yard pass to make it 28-21. The Packers would tie it up later on in the quarter when Williams ran for a 4-yard touchdown to make it 28-28. With seconds left, Chris Boswell would put up the game-winning 53-yard field goal to make the final score 31-28.
