O-line could look a lot different after bye week

IRVING, Texas -- The Cowboys’ offensive line could look a lot different after next week’s bye.
Offensive coordinator Bill Callahan said he is hopeful that Monday night’s matchup with the Bears would be the last game that Phil Costa misses due to back problems that have bothered him since training camp. Once Costa has recovered, there could be an interesting conversation among the coaching staff about whether Costa or Ryan Cook should start at center.
There could also be a change made at right guard, a topic Callahan and head coach Jason Garrett danced around but didn’t deny Wednesday. The Cowboys have the option of replacing struggling Mackenzy Bernadeau with Derrick Dockery, a veteran with 113 career starts.
