Quarterback Tony Romo (back), linebacker Sean Lee (neck) and linebacker Ernie Sims (groin) were the only players out of practice Wednesday.
Romo continues to undergo treatment on the herniated disc in his back.
"I saw him briefly today, and he's fighting through it," Cowboys coach Jason Garrett said Wednesday. "He's certainly in a situation where he's trying to do everything he can to get himself back. He's going through the rehab process and the treatment process like any injured player would. He's a tough guy as we saw the other day. We'll just see how he does."
Garrett was asked if Romo's pain level has decreased since he had an epidural shot.
"He certainly doesn't seem overly comfortable, so he's clearly working his way back through it," Garrett said.
Romo is not expected to play Sunday, but the Cowboys have not ruled him out. Kyle Orton was working with the first team, and Jon Kitna also was on the practice field as the second quarterback.
