AFC Championship, 2004: New England 41 Pittsburgh 27

Game information
The game-time temperature of 11 °F (−12 °C) made it the second-coldest game ever in Pittsburgh and the coldest ever in Steel City playoff annals. However, it was the Patriots that handed Ben Roethlisberger his first loss as a starter after a 14-game winning streak, the longest by a rookie quarterback in NFL history, as the Steelers became the second NFL team ever to record a 15–1 record and fail to reach the Super Bowl. The Patriots converted four Pittsburgh turnovers into 24 points, while committing no turnovers themselves. The Patriots' win also prevented an all-Pennsylvania Super Bowl from being played.

The Steelers never recovered from their poor performance in the first quarter. Patriots safety Eugene Wilson intercepted Roethlisberger's first pass of the game on his own 48-yard line, setting up Adam Vinatieri's 48-yard field goal to take a 3–0 lead. Pittsburgh responded with a drive to the Patriots 39-yard line. But then running back Jerome Bettis lost a fumble while being tackled by Rosevelt Colvin and linebacker Mike Vrabel recovered it. On the next play, Tom Brady threw a 60-yard touchdown pass to receiver Deion Branch.

Later on, the Steelers took advantage of Josh Miller's 27-yard punt that gave them the ball on their own 48-yard line. Roethlisberger completed a 19-yard pass to Hines Ward on the next play, setting up Jeff Reed's 43-yard field goal that cut the score to 10–3 with 1:26 left in the first quarter. But after an exchange of punts, Branch caught a 45-yard reception on Pittsburgh's 14-yard line. Two plays later, Brady threw a 9-yard touchdown pass to David Givens. Then on the Steelers ensuing drive, safety Rodney Harrison intercepted a pass from Roethlisberger and returned it 87 yards for a touchdown, giving the Patriots a 24–3 halftime lead.

In the second half, the teams scored three consecutive touchdowns. New England was forced to punt on the opening drive of the third quarter, and Antwaan Randle El returned the ball 9 yards to the Steelers 44-yard line. Then on the Steelers ensuing possession, he caught two passes for 46 yards as they drove 56 yards in five plays. Bettis finished the drive with a 5-yard touchdown run, cutting their deficit to 24–10. New England responded by moving the ball 69 yards in seven plays and scoring with Corey Dillon's 25-yard touchdown run. But Pittsburgh stormed right back, driving 60 yards in ten plays and scoring with Roethlisberger's 30-yard touchdown pass to Ward. Then after forcing a punt, Randle El returned the ball 22 yards to the Steelers 49-yard line. On their ensuing drive, Ward's 26-yard reception on the last play of the third quarter set up Reed's second field goal, making the score 31–20 with 13:32 left in the game.

However, the Patriots took over the rest of the quarter. They responded with a 49-yard drive that took 5:26 off the clock and ended with Vinatieri's 31-yard field goal. Then two plays after the ensuing kickoff, Wilson intercepted another pass from Roethlisberger at New England's 45-yard line. The Patriots subsequently marched down the field on another long scoring drive, taking 5:06 off the clock. Branch capped it off with a 23-yard touchdown run on a reverse play, giving the Patriots a 41–20 lead. The Steelers responded with Roethlisberger's 7-yard touchdown pass to Plaxico Burress on their next drive, but by then there was only 1:31 left in the game.

Brady completed 14 of 21 passes for 207 yards and 2 touchdowns. Dillon rushed for 73 yards and a touchdown. Branch caught 4 passes for 116 yards, rushed for 37 yards, and scored two touchdowns. Roethlisberger threw for 226 yards and 2 touchdowns, and rushed for 45 yards, but was intercepted 3 times. Ward caught 5 passes for 109 yards and a touchdown.

This was the fourth postseason meeting between the Patriots and Steelers. New England had won two of the prior three meetings.
