"Ed Dickson did some running [Monday], so we are just going to see how that knee continues to develop. There is no injury in there. It was kind of a hyperextension deal, so he has a chance."
Harbaugh offered no substantive update on injured middle linebacker Ray Lewis, who remains on the injured reserve-designated to return list with a surgically-repaired torn right triceps. Lewis is expected to return at some point this season, but has yet to resume practicing.
"Ray is here rehabbing," Harbaugh said. "Nothing to report there. We'll just see how that goes this week, and we'll let you know."
For the second consecutive game against the Steelers, wide receiver Torrey Smith was contained.
After catching one pass for seven yards when targeted seven times in a 13-10 win at Heinz Field, Smith was held to three catches for 33 yards on eight targets Sunday.
"Yeah, it's definitely frustrating," Smith said. "Regardless of how tough it may be, it's my job to make the play and more often than not I make it. But there were a couple of plays that I'm very upset about."
Flacco was inaccurate and out of rhythm on the majority of his deep shots to Smith, but the former University of Maryland standout was culpable for failing to secure one accurate bomb.
"You guys saw them," Flacco said. "I'm going to have to look back at them to see what happened. I think we missed a couple of opportunities early in the game to take a better hold of the game. I thought we could have put up 30 or 40 points, and we didn't do it. That's probably the best reflection that we hurt ourselves a little bit."
Oher beaten by Harrison
It was a bitter pill to swallow for Ravens offensive tackle Michael Oher.
Steelers outside linebacker James Harrison looped around him in the fourth quarter, evading his blocking attempt to sack Flacco and force a fumble recovered by defensive end Ziggy Hood.
It was a pivotal moment, leading to Miller's touchdown catch on the ensuing series.
"He's a good player," Oher said of Harrison. "You've got to account for him. You can always get better. We can do a lot of things better."
The turnover was reminiscent of strong safety Troy Polamalu stripping Flacco in a Dec. 5, 2010 loss to Pittsburgh.
“I had been bull-rushing all game,” Harrison said. “On the sack, I basically set up the same way. It looked like I was going to bull-rush, but I just slapped the hands (of Oher). I just hand-played him outside. Flacco held on to the ball a little longer than usual and I was able to get my hand in there."
Flacco waited in vain for receivers to create separation.
"Everybody was covered downfield," Flacco said. "I was getting ready to tuck it and chalk it up as a loss. The guy came around and hit my wrist. He hit the ball and just got it out. I tried to hold, but I couldn't."
Cornerback Jimmy Smith remains out indefinitely after having sports hernia surgery in November.
"Jimmy Smith continues to get better," Harbaugh said. "So, he will be moving around a little this week. We'll see how that goes.
