In anticipation of some potential season-ending injuries, the Cowboys made a roster move Saturday by releasing wide receiver Andre Holmes, according to a source.

Holmes was supposed to compete for the No. 3 receiver job in training camp, but he got off to a slow start when he failed the conditioning test. Despite making the squad, he also battled some knee problems. Holmes didn't get much work on the offense but played special teams.

He was active for seven games with his only notable play a recovery of an onside kick at Baltimore late in the fourth quarter in an eventual Cowboys loss.

Holmes finished with two catches for 11 yards and three special teams tackles. He caught one pass for four yards in the Thanksgiving Day loss to the Washington Redskins.

Who replaces Holmes on the roster is uncertain. The Cowboys most likely will lose inside linebacker Bruce Carter for the season when he undergoes elbow surgery next week, and cornerback Orlando Scandrick had surgery Friday to repair a broken hand. Scandrick's long-term status hasn't been determined.

The Cowboys worked out veteran receiver Anthony Armstrong this week and could sign him to the active roster. Miles Austin (hip) and Kevin Ogletree (concussion) are battling injuries and their status for the Philadelphia game Dec. 2 hasn't been determined.
