ARLINGTON, Texas -- The Cowboys made three changes to the offensive line in practices this week.
Then there's Mackenzy Bernadeau. He moved from starting right guard to left guard.
Coach Jason Garrett said the switch for Bernadeau isn't a big deal. Bernadeau played center and left guard in his career.
"He's played a little bit of both throughout his career," Garrett said Thursday before the Cowboys' open practice to the fans at AT&T Stadium. "He's also played center, as you guys know, (and) that was one of the reasons why he was an attractive player to us.
"He's kinda of a developmental guy who hadn't played that much when we signed him. We felt like he had some potential, and not only potential, but also some versatility. We don't think that's a huge issue for him cause he's done a little bit of that in his career in the past. The stance doesn't seem to be an issue, just where the defenders are doesn't seem to be a problem for him either."
Garrett said Free has to make an adjustment to playing guard because he's used to blocking defenders coming from an angle. As a guard, defenders come more at him straight up and in tight spaces.
Parnell has to get used to playing on a regular basis, given his limited time as a NFL player and the fact he missed practice time this summer with a hamstring injury.
Garrett said discussions haven't occurred yet regarding if the new first-team line will debut Saturday against Cincinnati. But every indication says it will.
