The Cowboys agreed to terms with OG Mackenzy Bernadeau, who has played for the Panthers since entering the league in 2008.
Bernadeau played in all 15 games last season with one start. He had 12 starts in 2010. Bernadeau has appeared in every game but one over the past three seasons.
The 26-year-old Bentley (Mass.) product stands 6-foot-4 and weighs 308 pounds.
The way we see it
OGs Montrae Holland and Derrick Dockery are free agents, and the Cowboys were unable to sign ex-Saints Pro Bowl OG Carl Nicks, who signed with the Buccaneers. Bernadeau joins a group of young, interior linemen.
