Ravens and Steelers updates

I have a few roster moves to pass along from the Baltimore Ravens (5-5) and Pittsburgh Steelers (6-4). Both teams play this week in a huge AFC North matchup with playoff implications.

First, for the Ravens, the team placed cornerback Fabian Washington (knee) and running back Matt Lawrence (knee) on season-ending injured reserve. Baltimore signed two additional players to take up those roster spots in fullback Charles Ali and cornerback Cary Williams.

For the Steelers, in an effort to boost their special teams they signed veteran cornerback Corey Ivy and linebacker Rocky Boiman. Pittsburgh released cornerback Keiwan Ratliff and linebacker Donovan Woods to make room for the two moves.

(Update: The Cleveland Browns also announced Tuesday evening that the team released linebacker Josh Stamer, who was signed last week.)
