Anthony Spencer returns to practice

IRVING, Texas -- Cowboys outside linebacker Anthony Spencer, who missed the Week 4 game against Chicago with a pectoral muscle injury, participated in Monday's practice at Valley Ranch.

Spencer did individual drills and some game-plan work but "not everything" in practice.

"I feel good," Spencer said. "I feel way better than I did last week. No setbacks."

Spencer was off to a strong start before his injury. He has 21 tackles, two sacks, nine quarterback pressures and two tackles for loss. Prior to the Bears game, Spencer was leading the team in quarterback pressures.

Victor Butler replaced Spencer in the lineup and finished with one solo tackle.

It appears Spencer will play this week at Baltimore, and if that's the case he'll wear a harness to stabilize the shoulder area.

Other injuries of note: Punter Chris Jones (knee) and center Ryan Cook (hamstring) missed practice. Several players, including wide receiver Miles Austin, were getting some extra stretching on their hamstrings.
