Dez Bryant has minor hamstring injury

Cowboys WR Dez Bryant pulled up with a tweaked hamstring in Saturday's practice.  He'll likely be held out of Monday night's preseason opener against the Raiders.  "At this juncture, I don't have anything to be concerned about," owner Jerry Jones said of Bryant's status.  It sounds like a very minor injury, but hamstrings can be tricky.  We'll keep an eye on Dez over the next few weeks.
