IRVING -- If you thought Alex Barron was done playing for the Cowboys, think again.

Barron, who committed three penalties, two holding calls in the fourth quarter, in Sunday's loss to the Washington Redskins might get some snaps in the Week 2 game vs. the Chicago Bears.

Starting right tackle Marc Colombo is expected to start the game, but he's coming off minor knee surgery and the Cowboys want to be cautious with his return.

The same could be said of left guard Kyle Kosier, who also recovered from a knee injury. Montrae Holland, who played well in the Week 1 opener, could also play.

How the Cowboys switch the players hasn't been determined.

"I think you have to have a feel for that during the game," coach Wade Phillips said. "Just like I said last week, we had some guys that were fresh we wanted to substitute for but they we're doing well."

Colombo came back from ankle surgery and a broken left fibula to play in last season's NFC wild card game where he was involved in all the offensive snaps (82) in the victory over the Philadelphia Eagles. In the NFC divisional round game, a loss to the Minnesota Vikings, Colombo participated in 67 snaps.

Colombo didn't have his best game vs. the Vikings, as he allowed two sacks and two quarterback hits.

There was a thought he came back too soon.

But with Barron's mistakes in the game it raises concerns about whether or not the Cowboys trust him. Barron said he wants another chance and owner/general manager Jerry Jones expressed confidence in him.

"I'm glad that we have Barron," Jones said.
