The Dallas Cowboys could be facing a very interesting situation at center against the Cleveland Browns on Sunday, as center Ryan Cook has been listed as doubtful after missing practice all week with a sore knee. Phil Costa, the team's stated starter at center, remains out with an ankle injury.
If Cook cannot play on Sunday, the Cowboys would slide guard Mackenzy Bernadeau to over, who has been taking the majority of reps at center this week in practice. It would be Bernadeau's first career start at center, with Derrick Dockery taking his spot at right guard.
Also not practicing, once again, was running back DeMarco Murray, who was listed as doubtful for the Browns game. With a quick turnaround before the Thanksgiving Game just four days later, it's likely that Murray will not play against the Redskins if he misses Sunday's contest against Cleveland.
Cornerback Mike Jenkins (back) is also listed as doubtful, with tight end John Philips (ankle), Jay Ratliff (ankle) and fullback Lawrence Vickers (knee) probable against the Browns. Matt Johnson (hamstring) and defensive lineman Sean Lissemore (ankle) are out.
