Cowboys vs. Browns injury report: Centers Phil Costa, Ryan Cook miss practice

The Dallas Cowboys injury troubles continued in the wake of the team's 38-21 victory over the Philadelphia Eagles, as both Ryan Cook and Phil Costa missed practice on Wednesday. The Cowboys have started both centers at times this season as they have battled through injuries, with Cook missing practice with a sore knee.

With Cook and Costa out on Wednesday, guard Mackenzy Bernadeau took reps at center with Derrick Dockery playing guard with the first team.

Running back DeMarco Murray could also be in danger of missing the upcoming game against the Cleveland Browns, sitting out practice while working on rehab for his injured foot. Murray has missed four games with the injury and if he cannot play on Sunday, he could miss the Thanksgiving game against the Washington Redskins, as well.

Also missing practice on Friday were Mike Jenkins (back spasms), safety Matt Johnson (hamstring), defensive end Sean Lissemore (ankle) and fullback Lawrence Vickers (knee).

Linebacker Dan Connor (neck) and Jay Ratliff (ankle) both had full participation with the team on Wednesday.
