W2W4: One more practice before a day off

OXNARD, Calif. -- The Cowboys will have their ninth practice of training camp Tuesday before a day off.

Backup corners: Monday when Orlando Scandrick went down briefly with a twisted ankle, it moved Akwasi Owusu-Ansah to the first-team with Brandon Carr. Injuries to Teddy Williams, Mike Jenkins and Morris Claiborne raised issues about the depth at the position as it allowed some inexperienced players to get more snaps. C.J. Wilson had a strong Monday practice and the Cowboys matched up Mario Butler against Dez Bryant a few snaps. The Cowboys might keep five corners this season. Carr, Jenkins, Claiborne and Scandrick are the main ones. But the uncertainty of when Jenkins will play could bring Owusu-Ansah or Wilson to make the 53-man roster.

Not ready for Oakland yet: Coach Jason Garrett said the Cowboys won't prepare for the Oakland Raiders, whom the Cowboys meet Monday night on ESPN, early this week. Instead the Cowboys will continue with their installation plan and work on situational plays. The Cowboys will work on the Raiders during the end of the week.

Offensive line movement: If the preseason opener was today, right now, at this moment, Ronald Leary and David Arkin would start at guard surrounding center Phil Costa. The Cowboys seem comfortable with this alignment going into the preseason opener. For continuity this is the best thing but maybe the team should consider giving Derrick Dockery and Daniel Loper snaps with the first-team early next week. if Mackenzy Bernadeau returns soon from his injuries, he will also get snaps at not only guard but also center.
