Cowboys welcome Colombo, Kosier back to practice as offensive line may get back to normal

Dallas linemen back at practice

IRVING, Texas — For the first time in a month, Tony Romo has taken a snap behind the guys he’s counting on to be the front wall of the Dallas Cowboys’ offense.

Right tackle Marc Colombo and left guard Kyle Kosier returned to practice Wednesday, replacing the fill-ins who were partly to blame for the offense’s poor showing in a season-opening loss at Washington on Sunday night.

If all goes well, Colombo and Kosier would play in the home opener Sunday against Chicago.

Their return would bump Alex Barron from right tackle and Montrae Holland from left guard. Barron had three holding penalties against the Redskins. One came on the final play, wiping out a potential game-winning touchdown catch and costing Dallas the game.
