While Buffalo (8-4) is back in the winner's circle, Pittsburgh (6-6) has lost two straight games and five of its last seven. Sunday was another brutal showing for a Steelers offense that gained just 166 yards and possessed the ball for less than 19 minutes.

The Steelers rank 12th in the NFL with 25.3 points per contest on offense, and they rank 21st with 24.4 points ceded per contest on defense. The Chargers rank 16th in scoring offense (23.9 points per game) and 11th in scoring defense (21.4 points allowed per game) this season.

Just one day after being placed on waivers, Aaron Rodgers and the Pittsburgh Steelers, who are on the hunt for the playoffs, signed Adam Thielen on Tuesday.

The Buffalo Bills, Dallas Cowboys and Houston Texans picked up must wins as the NFL's postseason picture begins to get clearer in Week 13.

This week the Steelers square off with the Chicago Bears and will do it with Mason Rudolph at quarterback. Keep up with all the action here.
