Dez Bryant part of walk-through

OXNARD, Calif. -- One day after leaving practice with a left hamstring strain, Dallas Cowboys receiver Dez Bryant worked with the starters during Sunday's walk-through and will be a game-time decision for Monday night's preseason opener against the Oakland Raiders.

The Cowboys will determine whether Bryant will play after he warms up before the game.

Bryant's left hamstring tightened during the middle of team drills Saturday, but he said he was "fine" as he walked off the field.

Cowboys owner and general manager Jerry Jones said Saturday if there was any "sensitivity" to further injury then Bryant would not play against the Raiders.

"At this juncture, I don't have anything to be concerned about," Jones said Saturday.

The Cowboys already are without wide receiver Miles Austin, who also has a hamstring strain.

Kevin Ogletree, who is subbing for Austin, and Dwayne Harris worked as the starting receivers to close Saturday's practice.

"This early in camp we're not going to push hamstrings," Jones said. "That's just the policy, and this is exactly why we have the policy. When a player gets a little tightness, then we will be very conservative. The word is conservative, how much he pushes it, and there wasn't any need of him to go through the last drill. And that may be the extent of the precaution."

Austin has not practiced in a week because of his strain. He missed six games last season with two hamstring injuries, and the Cowboys will be cautious given his history with the injury.

The Cowboys will be without at least six expected starters for Monday's exhibition opener.

Declared out are Austin, rookie cornerback Morris Claiborne, Pro Bowl nose tackle Jay Ratliff (foot), defensive end Jason Hatcher (groin), linebacker Anthony Spencer (hamstring) and center Phil Costa (back).
