Center Joe Looney has had added reps during training camp thus far and extended experience on the field during preseason. Starting center Travis Fredrick continues to have neck evaluations, after enduring several stingers in the week 1 preseason game against the San Francisco 49ers. The Cowboys are hopeful that their pro-bowl veteran will be back for the season opener against the Carolina Panthers, but until that time Looney is the guy in the middle leading the offensive line.
