SAN ANTONIO – The contingency plan at center is for left guard Kyle Kosier to slide over if Andre Gurode goes down.

Kosier has yet to get a rep at center during training camp. That will change tomorrow.

Travis Bright, who spent last season on the practice squad as a guard, is trying to make the transition to center. He has taken every rep with the second team so far in camp, but he’s struggling at his new position.

Kosier has never played center, either. While Bright focused on that position during the offseason, Kosier got limited reps there. However, Wade Phillips said he didn’t think it’d be a problem for Kosier to prepare to play center even though he’ll remain the starter at left guard.

If Kosier struggles at center, the Cowboys could have to sign a center to back up Gurode. The problem, other than finding a good fit, is that they plan to have only two reserve linemen active on game days. They want one of them to be guard Montrae Holland.
