Roster updates: Claiborne, Tanner sit out

OXNARD, Calif. -- The first roster change of training camp resulted in two new offensive linemen for Saturday morning's walkthrough.

Guard Derrick Dockery will wear jersey No. 75 today according to the roster released to the media. Dockery wore the same number last season.

Guard Daniel Loper is wearing No. 76. Last year, Loper wore No. 70. Jeff Adams has that number now.

UPDATE: On the practice field Dockery is wearing No. 76 and Loper is No. 75. Mix up in communications.

The Cowboys received some additions to the injury report in cornerback Morris Claiborne (knee) and running back Phillip Tanner (hand). Those players will miss Saturday's practice sessions.

Orlando Scandrick moves back to the first-team unit and expect Lance Dunbar to get some snaps with the second-team today.
