Marc Colombo, Kyle Kosier will practice

IRVING, Texas – Starting offensive linemen Marc Colombo and Kyle Kosier will practice Wednesday, but their status remains uncertain for Sunday’s game after sitting out the season opener due to knee injuries.

Colombo, the right tackle, underwent arthroscopic surgery to remove five loose particles from his right knee Aug. 16. Owner/general manager Jerry Jones said on the day of the operation that he expected Colombo to be sidelined only 10 to 14 days.

Kosier sprained the MCL in his right knee two days later. The timetable for his return was set at 4-6 weeks.

Coach Wade Phillips said he didn’t know whether either injured lineman would be able to play Sunday against the Chicago Bears.

“I don’t know about optimistic,” Phillips said. “There’s a possibility certainly. And I don’t really know which one, or both, or neither. We just have to wait until Wednesday and see what happens.”

Guard Montrae Holland and tackle Alex Barron replaced the two starters in the loss to the Redskins. Barron’s poor performance played a major role in the loss. He had three holding penalties, including one to negate a touchdown pass to Roy Williams on the final play of the game.
