LONDON – The circumstances are unique, but Cowboys coach Jason Garrett said it will be the usual schedule for Tony Romo on Wednesday.

Romo missed Wednesday morning's practice with the team, as has been his usual routine during the season. While the Cowboys bused to practice at Allianz Park in northwest London, Romo stayed behind at the team hotel to receive treatment on his injured back.

That said, Garrett added that Romo participated in the team's Wednesday morning walkthrough and appears to be moving around well. Asked if Romo's absence was routine or related to injury, Garrett replied with a bit of both.

"Following a normal schedule but also listening to his body," Garrett said. "We had a good productive walkthrough at the hotel today, and we anticipate him adopting that schedule that we've had for most of the year."

Romo has not gone through a team practice since he injured his back in the Oct. 27 loss to Washington, though Garrett added he's hopeful the quarterback can do some work Thursday.

Elsewhere, the Dallas offensive line got a boost as both Doug Free and Ronald Leary returned to practice. It was Free's first sighting on the practice field since he fractured his right foot in the Oct. 12 win against Seattle. Leary missed all of last week with a groin injury he sustained in the loss to the Redskins.

Defensively, Rolando McClain missed practice as he continues to recuperate from injuries to his groin and knee. The groin injury has hampered McClain throughout the season, and it hasn't been uncommon to see him participate more as the week has gone on. Garrett replied "we'll see" when asked about McClain's availability Wednesday.

Tyrone Crawford and Nick Hayden also sat out of practice. Crawford remained at the team hotel to receive treatment on his sprained MCL, while Hayden attended practice and did not participate.
