In six seasons under coach John Harbaugh, the Ravens have never been under .500 at this stage of the season - until now.
Baltimore became the first defending Super Bowl champion with a losing record after seven games since the Steelers in 2006 following Sunday's 19-16 loss in Pittsburgh.
It wasn't a bad showing for the Ravens, who never led but came back from down 10-3, 13-6 and 16-9 to tie the game with less than two minutes remaining.
But kicker Shaun Suisham was the star for the Steelers, converting all four of his field goal tries, including the 42-yard game-winner as time expired. Suisham is now 14-for-14 this season.
It felt like a typical Ravens-Steelers game even with a whole new cast of characters, and the way this one finished with a late comeback and winning boot kept the tradition alive.
Quarterback Joe Flacco had a solid performance, going 24-for-34 for 215 yards and a touchdown. His tying drive was his most impressive, as he went 9-for-10 for 60 yards in helping Baltimore eat 8:01 off the clock in the fourth quarter.
But Pittsburgh was able to maneuver from its own 37 into field-goal range to set up Suisham at the evry end.
The Ravens continued to have problems in the running game, finishing with 82 yards on the ground. Baltimore seemed to be the antidote for the Steelers' rushing woes, as Pittsburgh ran for a season-high 141 yards - more than twice its season average.
Baltimore outgained Pittsburgh 287-286, marking another strong day for the Ravens defense. Baltimore recorded three more sacks with Terrell Suggs coming up with his eighth in seven games.
But the Ravens' streak of three straight regular season wins at Heinz Field came to an end in another close contest. It was the ninth time in 11 meetings between the two teams that the game was decided by exactly three points.
With Baltimore at 3-4 and Pittsburgh now gaining life at 2-4 following back-to-back wins, the Thanksgiving rematch at M&T Bank Stadium is starting to look like it could be a meaningful one.
