Before Saturday’s training camp practice began, the Dallas Cowboys announced a series of roster moves. The Cowboys officially added two players to the roster, signing offensive tackles La’el Collins and Geron Christian.

If healthy, Collins can help solidify a Cowboys offensive line that was recently hit with an injury to starting left tackle Tyler Guyton. Cowboys coach Brian Schottheimer recently tabbed Asim Richards and Nate Thomas as two players "who'll get the first couple cracks" to temporarily replace Guyton, who is slated to miss the next 4-6 weeks.

Veterans La'El Collins and Geron Christian join a battered Cowboys OL. Injured WR Parris Campbell goes to IR; OL Matt Waletzko was waived with injury.
