LB Anthony Spencer expects to play

IRVING, Texas -- Dallas Cowboys starting outside linebacker Anthony Spencer said he expects to play in Sunday's game at the Baltimore Ravens. Spencer missed the Week 4 loss to the Chicago Bears with a pectoral muscle injury.

Spencer said he suffered a slight setback during the rehab of his injury, but that he feels better now.

Spencer didn't practice Monday and Wednesday but did some limited work on Thursday.

"Yeah, don't want to make it worse, just take a chill pill," Spencer said. "Just a little sore and got a little pain for the most part. The strength is there."

Spencer worked during the Thursday morning walkthrough and participated in individual and third down drills.

"I want to be careful with it," Spencer said of his injury. "Right now I feel like I'm going to play."

Also, punters Chris Jones (knee) and Brian Moorman (groin) didn't participate during the open media period of practice on Thursday. Jones has punted some this week and the Cowboys are waiting to see how he feels before making a final decision on whether or not he'll play in Baltimore. Moorman is out.

Center Ryan Cook (hamstring) didn't practice and if he doesn't play, center Phil Costa will return to the starting lineup. He started the first game of the season at the New York Giants, but left after just three snaps because he re-injured his back.
