Could Dockery's return mean change in line?

IRVING, Texas -- With Derrick Dockery close to returning from a knee injury suffered Week 2 at San Francisco, the Cowboys could look to switch around their offensive line.

Dockery could move to right guard with Kyle Kosier replacing Phil Costa at center. Montrae Holland will start for the second straight week at left guard.

“If they need me to I will,” Kosier said of a possible switch.

Kosier has not played center before, but he has worked the spot in practice the last two years. He was the gameday backup center to Andre Gurode most of last year.

“It’s not easy to make the calls, loud stadium with your head down on a silent count, snaps the ball too,” Kosier said. “It’s not an easy deal. I respect those guys for doing that.”

Dockery, who started the Niners game, was limited in practice on Wednesday and Thursday.

“I think he’s had a good week of practice,” Garrett said. “We’re all hopeful he’ll get better as he practices. It seems like he’s moving around well and getting himself back into football shape physically and you can tell he’s progressed well this week.”
