Defensive end Marcus Spears said he would have an MRI on his left calf injury he suffered in the third quarter. He did not return.
Defensive end Sean Lissemore was on crutches after the game with a left ankle injury.
The Cowboys finished the game with four defensive linemen, which forced Jay Ratliff to see some time at end in the regular defense and rookie Josh Brent manning nose tackle.
Roy Williams said he was feeling fine after taking a big hit in the back from Green Bay safety Nick Collins after an incomplete pass. Williams remained down on the field and received medical attention.
"I was fine, but I just wanted to make sure everything else was alright before I got up," Williams said.
With the focus on hitting defenseless receivers, Collins is likely looking at a fine from the NFL. Jacksonville's Don Carey was fined $12,500 for a hit on Jason Witten last week.
Terence Newman said his sore ribs were feeling better after the game but that he could still feel the pain from the muscle strain and cartilage tear.
