IRVING, Texas -- The Cowboys added some new names to the injury report Wednesday, and wide receiver Miles Austin was listed with a knee injury. Austin had his right knee wrapped, although he was a full participant in practice. Austin was on the report last week with a hamstring.

Starting outside linebacker Anthony Spencer is on the injury report with a shoulder injury and he was limited in practice. Starting left guard Bill Nagy was on the injury report with a neck problem and he was limited in practice. That would explain why Derrick Dockery got some reps with the first team during Wednesday's practice.

Wide receiver Dez Bryant did not practice with a thigh injury. He was a little gimpy as he walked through the locker room on Wednesday afternoon.

Cornerback Terence Newman, who was expected to practice on Wednesday as he recovers from a groin injury, did not practice.

Also, Mike Jenkins who is battling a bruised shoulder, was limited in practice, but said he would do more work on Thursday. Tight end Martellus Bennett (ankle) fully returned to practice.

Right tackle Tyron Smith (knee) and center Phil Costa (knee) practiced with no issues on Wednesday. Cornerback Orlando Scandrick didn't practice as he recovers from a sprained right ankle. Scandrick, who is wearing a protective boot, hopes to return soon.

"I'm trying to stay upbeat and listen to the trainers and stay off it," Scandrick said. "The biggest thing is staying in it mentally."

Scandrick said he injured the ankle on the second play of the New York Jets game Sunday night and tried to play through it, but couldn't after the second defensive series.

Losing Scandrick and possibly not having Newman makes for a thin secondary.

"It's very frustrating," Scandrick said. "I was looking forward to getting Terence back and all of us playing together."
