It's the first time the Cowboys were back on the field since Ware and Barber got hurt in the team's Thanksgiving Day victory over Seattle.
MRI tests Friday revealed no significant damage for Ware and Barber. Phillips expects Ware to practice this week, but was less certain about Barber.
Also: Cornerback Mike Jenkins (hamstring) and receiver Miles Austin (sprained left knee) were held out of practice.
The Cowboys put left guard Kyle Kosier on injured reserve, ending his season after he played in only three games because of a right foot injury.
Kosier re-injured his foot twice trying to return.
He played in only one of the first nine games, then got back for only two more before missing Thursday's game.
Dallas signed rookie linebacker Steve Octavien off Washington's practice squad.
Cornerback Adam "Pacman" Jones will be eligible to play Sunday at Pittsburgh after his six-game suspension.
Jones has already returned to practice, but the Cowboys still have a roster exemption and do not yet have to put him on their 53-man roster. Jones recently finished alcohol-related rehab.
