If a hamstring injury prevents Ravens inside linebacker C.J. Mosley from playing in Sunday's game at the New York Giants, the defense will lose a playmaker who leads the unit in interceptions (three) and ranks second in tackles (29).

But the team won't worry about who will replace Mosley as the primary communicator.


Fellow inside linebacker Zachary Orr has in previous years worn the green dot helmet that enables him to receive play calls from defensive coordinator Dean Pees and relay them to his teammates. Pees confirmed that Orr will handle that responsibility again if Mosley is out.

"Obviously, when I'm out there with C.J., I haven't been doing it." Orr said. "But whenever C.J. came out of a game, I was doing it. Even in my rookie year, I was doing it when I was in, late in the game. I had the headset and every day in practice, I had the headset with C.J. So I'm used to hearing the calls and relaying them.

"...When C.J. went out [in Sunday's 16-10 loss to the Washington Redskins], I did it in the latter part of the third quarter, and I don't think we'll have any problems. I think everything will go smooth."

The Ravens usually work in several players during practices to get them accustomed to handling the calls. When Ray Lewis played in just six games in 2012 because of a torn right triceps, Albert McClellan replaced him as the defensive play caller.

"We have about four or five guys, linebackers that have done the helmet communication in practice," Pees said. "In fact, earlier in the season in training camp and OTAs when you have the helmets on, they all have a headset. There's no rule; that's just in the game. So in practice, they all kind of have the headset so that they all get used to hearing. So that's usually not a big problem."

Handling a responsibility usually borne by Mosley might seem heavy for an undrafted free agent in just his third year in the NFL. But Orr, who leads the defense in tackles with 37 and has posted an interception, forced fumble and fumble recovery, said he is ready for the task.

"I guess you could say there's a little bit [of pressure] just to make sure everybody gets the call," he said. "But as a defense, we do a great job. I can tell one person, and that person is going to tell the next person, and we'll relay the call to everybody. There will definitely be a little bit of extra responsibility, but we're all in it together, and we'll be fine."
