Romo shuffled through the hallway on his way to a quarterbacks meeting before the workout. Asked if he felt better, Romo said, "Oh, yeah. I feel like a hundred dollars."
The Cowboys (9-6) close the regular season Sunday in Philadelphia and would earn an NFC wild-card spot if they win. They would miss the playoffs with a loss.
"We'll make him practice double today," Cowboys coach Wade Phillips said of Romo with a smile. "We'll make him practice extra so he can catch up for people who worried about him missing practice yesterday."
Tight end Jason Witten (sprained left ankle) also returned to practice after missing Wednesday's workout. Running back Marion Barber (dislocated right pinkie toe) and safety Ken Hamlin (foot) practiced, too.
Witten and Hamlin are expected to play against the Eagles. Barber likely will be a game-time decision.
