Dumervil jumped offsides and then delivered a late hit after quarterback Ben Roethlisberger had already released a pass intended for Jerricho Cotchery that fell incomplete.

"I got to do a better job of being aware of the strike zone," Dumervil said. "I think I played a little too aggressive. I have to do a better job and not cost the team."

Later in the drive, Dumervil combined with nose tackle Haloti Ngata for a sack on third down at the Ravens' 17-yard line.

It was nullified, though, because Dumervil committed a facemask penalty that led to a Steelers field goal.

"You just can't grab the facemask, but Ben ducks all the time," Harbaugh said. "What do you say? This is the biggest, strongest quarterback in the NFL. We have to wrap him up strong and bring him down, but you feel yourself around the face area, he drops down, you have to get your fingers out of there somehow. Maybe there's a way to coach that other than talking about it, but you don't want to get the facemask."

Osemele to be re-evaluated after season

Although left offensive guard Kelechi Osemele will have his back evaluated again following the season, no surgical procedure is currently planned, according to a source with knowledge of the situation.

Osemele was forced out of a game against the Miami Dolphins due to back spasms. He had his back examined thoroughly prior to the season and no surgery was recommended, per the source.

Osemele has had an up-and-down season and the source said the player is dealing with some frustrations.

Wildcat attack

The Steelers broke character offensively and a bit of new ground as they ran a handful of Wildcat plays.

The Ravens admitted that the gambit caught them off guard.

"They did some new things that we haven't seen from them, not just all year but like ever," outside linebacker Terrell Suggs said. "Pittsburgh has never come out and run the Wildcat on us. They've never come out and run with extra linemen. You just got to be able to adjust on the fly."

The Steelers finished with 141 rushing yards on 29 carries, averaging 4.9 yards per run. They had entered the game ranked 31st in rushing offense, averaging only 61 rushing yards per contest.

"We didn't do a good enough job," Harbaugh said. "The fact that they were able to run the ball the way they did was the thing that allowed them to extend those drives. We've got to get in there.

"We've got to put people up to defend the run. They did a real good job with the run game. They did a good job of scheming some things up."

Pierce 'banged-up'

The Ravens reported no serious injuries.

Backup running back Bernard Pierce aggravated a pre-existing leg injury, but emphasized it wasn't too bad.

"It's a little banged-up, but I'll be fine," said Pierce, who rushed for 13 yards on six carries. "I'll get through it. It's been lingering on the side of my leg."

End zone

In a move that triggered no surprise, the Ravens scratched veteran offensive tackle Bryant McKinnie for the second consecutive game. McKinnie was replaced last week by Eugene Monroe. The Ravens also deactivated wide receiver Brandon Stokley (groin), linebacker Josh Bynes (finger surgery), nose tackle Terrence Cody (sprained left knee), offensive lineman Jah Reid, center Ryan Jensen (foot surgery) and defensive tackle DeAngelo Tyson.
