IRVING, Texas -- Cowboys coach Jason Garrett said Tuesday he didn't anticipate any changes to the offensive line, even mentioning how good the pass protection was in the loss to the Chicago Bears.

On Wednesday morning, Garrett was asked again about potential changes and said none are coming.

There seems to be a thought that right guard Mackenzy Bernadeau should be benched in favor of Derrick Dockery. Most of the problems stem from Bernadeau's inability to block on a consistent basis from the right side.

The Cowboys have run just three plays toward Bernadeau's side for an NFL low 1.67 yards per carry.

"We like the five guys who are playing up front as we talked yesterday," Garrett said. "I think collectively as a group they blocked that front fairly very well, particularly in the passing game the other night against Chicago, and Mackenzy is apart of that. Like everybody on the football team, it can get better. He watched the tape this morning and there's some areas where he can improve and he's got to keep working at it. It's nice to have a guy like Dockery sitting right there where we feel like he's a guy who has some experience and we're certainly confident in his ability to go out there and play."

Garrett said Bernadeau wouldn't take any center snaps over Phil Costa or Ryan Cook. Garrett wants Bernadeau to focus mainly on the guard position.
