Cowboys hope Phil Costa back to practice Monday

ARLINGTON, Texas -- The Cowboys hope that their starting offensive line will finally get practice reps together Monday.

Center Phil Costa, who has been sidelined three weeks with a strained lower back, worked out before Saturday night’s game. Costa snapped to backup quarterback Kyle Orton and worked on his footwork, showing no noticeable signs of being hampered by back pain.

“He says he feels better,” coach Jason Garrett said. “We’ll evaluate him day to day. We’re hopeful he’ll practice on Monday.”

The chemistry of the interior offensive line, in particular, is a concern because Costa and free agent guards Nate Livings and Mackenzy Bernadeau have yet to work together.

Bernadeau missed the entire offseason and several training camp practices because he underwent hip and knee surgery. Livings was sidelined for much of training camp and the first two preseason games due to a strained hamstring.

“It’s a challenge, but it’s reality, so you make the best out of it,” Garrett said.

The vast majority of the Cowboys’ starters will not play in Wednesday’s preseason finale, but Garrett left open the possibility of Costa, Bernadeau and Livings getting some work in that game. Owner/general manager Jerry Jones said he expects Costa to play Wednesday.
