The Packers and Steelers ended with a tense scuffle on the sideline after a game-clinching interception by the Pittsburgh defense.
Green Bay had the ball in the red zone with just three seconds left on the clock, trailing 23-19 and needing a touchdown to win the game.
Quarterback Jordan Love had one shot to take at the end zone, and fired a pass towards wide receiver Christian Watson who was hovering along the goal line. Watson was beat to the ball by safety Damontae Kazee, who picked off the pass and began running it back as the clock hit zero.
