Cowboys starting safety Barry Church sat out Monday's walk-through after needing a root canal.
"I guess it's been bothering him for a little bit," Cowboys coach Jason Garrett said. "He's a tough individual, but I guess he had a little incident this morning, so hopefully we'll get that cleaned up and he'll be ready to roll."
Rookie J.J. Wilcox got first-team reps in Church's absence.
Defensive end Cameron Sheffield (groin) and offensive guard/center Ryan Cook (lower back) were not at practice.
Offensive guard Ron Leary and long snapper LP Ladouceur participated in the walk-through for the first time after passing their physicals.
