Cowboys' roster in state of flux

IRVING, Texas -- At 4-4, the Dallas Cowboys have issues entering the second half of the season.

The first thing they have to do is figure out the roster.

Injuries will force the Cowboys to manipulate several spots and they won’t have a lot of time to get it right.

Brian Waters is likely done for the season because of a triceps injury. He is holding out hope for a possible return, but the Cowboys might not have time to wait. They need to bring in an offensive lineman, likely David Arkin, just to have another guard available on game day. They could go with Phil Costa at center and move Travis Frederick to guard if something happened to Ronald Leary or Mackenzy Bernadeau, but they would like to keep Frederick entrenched at center.

The Cowboys are banged up at safety, as well. J.J. Wilcox’s sprained knee is feeling better, but he does not know if he can practice or play Sunday. Barry Church said he will play despite a hamstring strain suffered Sunday against the Detroit Lions, but the Cowboys have been cautious with hamstring strains this season. Danny McCray has toe, hip and hamstring injuries. Jason Garrett called McCray a “warrior,” but he might be too compromised to help. That leaves undrafted free agents Jeff Heath and Jakar Hamilton as the only healthy safeties, and Heath has a hand/wrist injury he’s dealing with.

Morris Claiborne is looking at a two-game absence because of a hamstring injury, according to a source, and the Cowboys have only three healthy corners on the 53-man roster. It seems they have to make a move at cornerback and at least call up Micah Pellerin from the practice squad.

The Cowboys also have to make a roster move to add defensive end Everette Brown.

Add in the unsure status of DeMarcus Ware (quadriceps), Miles Austin (hamstring) and DeMarco Murray (knee), and the roster is in a state of flux.

Oh, and the trade deadline is today at 3 p.m. Don’t look for any moves, but the Cowboys sure wish they could have more than 53 players on their roster right now.
