Cowboys turn to Mackenzy Bernadeau

IRVING, Texas – With Brian Waters’ season looking all but over because of a triceps injury, the Dallas Cowboys will look to Mackenzy Bernadeau once again.

Signed as an unrestricted free agent last season, Bernadeau started every game in 2012 and the first three games this season. Coach Jason Garrett said Bernadeau did a “good job” with the work Sunday against the Detroit Lions following Waters’ departure.

“Hopefully he's been positively influenced by watching Brian play and just learn from that experience as well,” Garrett said Monday before the team learned of the severity of Waters' injury. “He's played a lot of snaps for us and he's been banged up for the last couple of years and he's played a ton of football for us last year and a lot of football early for us. So hopefully he'll be ready to go and did a nice job getting his first snaps back in there.”

If the Cowboys give Waters the chance to get healthy, they might have to add a guard to the 53-man roster. They re-signed David Arkin to the practice squad on Monday after he was released over the weekend. He has not taken an offensive snap in two-plus seasons. They also have Ray Dominguez on the practice squad.

If they don’t make a move, then center Phil Costa would serve as the backup interior lineman on gameday.
