While the focus of late has been on the offensive woes of the Dallas Cowboys, they also have some concerns on the interior of the defensive line. Maliek Collins continues to be held out of practice as the team prepares for the game against the Detroit Lions, Datone Jones just went on IR, and Adolphus Washington was poached from the practice squad by the Cincinnati Bengals. The team added Caraun Reid to the 53-man roster earlier to fill in for Jones, and now they have signed Christian Ringo to take Washington’s PS slot.
