Lang, Sitton limited in practice, McCarthy says

Green Bay Packers coach Mike McCarthy spoke with the media for about 6 minutes after Thursday's practice in preparation for Sunday's game against the Philadelphia Eagles at Lambeau Field. Here are some highlights:

Injury report

Did not practice: TE Brandon Bostick (hip), LB Jayrone Elliott (hamstring). Limited: G T.J. Lang (ankle), G Josh Sitton (toe).

On how much Lang and Sitton did at practice:

T.J. Lang and Josh Sitton practiced in a limited fashion. They did not do any team drills.

On the Eagles' Darren Sproles' special-teams ability:

Big time. Darren Sproles has done it for a long time in this league. He's definitely a focus for us.

On Sproles' size being an advantage:

I think he does a great job of playing to his skill set. He has a very unique skill set. You talk about his height, he's very quick and explosive, but you don't talk about how smart he is. We'll be very matchup conscious on him. He's been an excellent player in this league for a long time.

On Lambeau Field being an advantage:

I think you have a tremendous advantage playing at home. You play to your environment at home, whether it's Green Bay or Miami.

On when is a good time to call a screen pass:

A good time to call a screen is when the defensive end flies upfield. That helps, but it's a feel. Playing calling is a feel. Philosophically, when you call it and when you don't, that's really up to the play caller.

On whether Clay Matthews told McCarthy he was unhappy about playing inside linebacker:

I have not. We obviously talked to Clay before the decision was made. He played extremely well. We'll see where he plays this week.

On the Eagles' ability to force fumbles:

Oh, definitely. We recognize that. That's something you can tell when you get the characteristics of a defense, the identity of a defense, how we match up. We definitely recognize their ability to take it away.
