Strong safety Bernard Pollard is out with a rib injury he aggravated during the Ravens' 31-28 overtime loss to the Washington Redskins last week. He'll be replaced by James Ihedigbo, a former New England Patriots starter.
Starting middle linebacker Jameel McClain had already been ruled out with a neck stinger and back injury and visited a back specialist in Los Angeles with the team awaiting second opinion test results.
Starting tight end Ed Dickson was ruled out because of a hyperextended knee, missing his third consecutive game.
Starting inside linebacker Dannell Ellerbe was ruled out after attempting to convince the coaches and trainers he was ready to play during warmups. He was questionable with a sprained right ankle and a left foot injury and was limited in practice for the past two days. Josh Bynes and Albert McClellan are slated to start inside.
"I'm going to work it before the game," Ellerbe said Friday. "If I feel good, I'm going to go. If I can't go, I'm not going to goout there and hurt the team."
Ihedigbo started a dozen games for the New England Patriots last season, recording 72 tackles and one pass deflection. For Baltimore this year, Ihedigbo has nine tackles and a sack.
"Definitely, I'm ready," Ihedigbo said. "It's been going well. Whatever's needed by me, I'm ready to do so. You've got to do whatever's asked of you as a player."
Defensive end Pernell McPhee is dealing with a groin injury, but is active.
