against the Redskins in Washington.
With Kyle Kosier all but ruled out as well with a slight MCL tear, this means that reserves Montrae Holland and Alex Barron will start at left guard and right tackle, respectively.
Colombo underwent arthroscopic knee surgery in mid-August to clean up some loose particles in the joint, but was expected, at the time, to return in time for the opener; his status was thrown into doubt on Wednesday, though, when he was held out of yet another practice.
The Cowboys hope Colombo will be healthy enough to return to practice next week, and play in the home opener next Sunday against Chicago. The timeframe for Kosier’s return is a little less clear; he may return for the home opener, but it’s equally likely that he’ll require another week of recovery after suffering the MCL injury on August 18.
