Overshown (hamstring) did not practice Wednesday, Patrik Walker of the Cowboys' official site reports.
Overshown has missed the Cowboys' last four games due to a hamstring injury he sustained in Week 1 against the Giants. He's also been held out of practice since picking up his injury, so he would have to log at least a limited session over the next two days to have a realistic shot at returning for this Sunday's road game against the Packers.
