Steelers linebacker Jarvis Jones, suffering from a concussion, is listed as questionable for the game vs. Baltimore on Sunday.

Jones said Friday that his headaches have dissipated, but after a series of NFL-mandated tests, he has not been cleared. He worked out on Friday at team headquarters, then took another exam before the injury report was issued.

"We're still taking precautions and going through the steps and trying to do the right things in the process for this type of situation," Jones said. "So, we're just taking it slow. We've still got two more days before the game. We'll see what they say."

If Jones can't start, veteran Jason Worilds is expected to reclaim the role that he lost in Game 2 at Cincinnati.
