IRVING, Texas -- Dallas Cowboys outside linebacker DeMarcus Ware will start Sunday's game against the Washington Redskins, but he may be limited to some passing situations because of a shoulder injury.

"I think we're going to have to watch how many plays we give him," defensive coordinator Rob Ryan said Friday. "We've got good players here, so we're going to play them. There's only one DeMarcus Ware. There's only one Sean Lee. But we've had to function without Sean. Now, sometimes we've had to function without DeMarcus. I mean, these are two of the premier guys in football. Nobody's got them except us. But we're fortunate to have them, and when we don't we have to move on. We'll do the best we can."

Ware said earlier this week that he'll wear a harness over a shoulder that keeps popping out and may need surgery in the offseason, which could eliminate him from playing in the Pro Bowl. Ware is also playing with a brace to protect a hyperextended elbow.

Ware's backup, Victor Butler was limited in Friday's practice with a groin injury but is expected to play.

Ryan said he liked the Cowboys' pass rush in the first meeting with the Redskins on Thanksgiving Day. The Cowboys sacked Redskins quarterback Robert Griffin III four times, but he was still able to throw for 311 yards and four touchdowns. Griffin also completed four pass plays of 20-or-more yards.

Ware said this week he can't put too much pressure on himself to make big plays.

"You can’t try to put too much on yourself," he said. "The plays that come your way are the plays you're able to make, those are the plays you need to make because there are 10 other guys out there that are playing really well. So it's going to come down to one of those games where you always say you got to stop the run, and when it comes time to pass you got to get pressure on the quarterback. That’s what we have to do."
