Dallas Cowboys wide receiver Miles Austin won't practice today at Valley Ranch due to a hamstring injury. Austin suffered the injury in last week's victory over the St. Louis Rams.

Austin has a history of hamstring problems but had not dealt with one since last season.

"We can be a little more conservative today" Cowboys general manager Jerry Jones said of Spencer.

Coach Jason Garrett said Austin did not return to the game as a precaution because the Cowboys were ahead by more than two touchdowns. Still the team has to be concerned about Austin's health given his history.
