The Dallas Cowboys are preparing to board a plane to Oxnard, CA so that they can get the ship going in the right direction. On Monday, the club will travel in advance of Wednesday’s start to training camp practice. While things seemed relatively smooth heading into July, things have been shaken up a bit by contract situations that are not ideal for the players in question.

Also, the team has a small number of injury concerns that may or may not impact eligibility to be full participants once the on-field work begins. Check below on the latest updates from ESPN’s Todd Archer on Zack Martin, Jourdan Lewis, Terence Steele and Tony Pollard.
