Bass dislocated his left shoulder during Thursday's practice, and he will undergo an MRI on Friday. The early prognosis is that Bass will miss anywhere from two to four weeks.
This puts even more pressure on an already thin group of defensive tackles. Bass and
Jay Ratliffare currently injured, and the Cowboys traded Sean Lissemore to San Diego on Sunday. That leaves Landon Cohenas the only reserve defensive tackle on the current roster, behind starters Jason Hatcherand Nick Hayden.
The defensive line has borne the brunt of the injuries for the Cowboys in 2013. In addition to Ratliff, Tyrone Crawford was lost for the season on the first day of training camp. And Anthony Spencer is expected to miss the opening game against the New York Giants, leaving Dallas short at defensive end as well.
It is possible that the team may use newly acquired Caesar Rayford to try and help at defensive tackle. His recent acquisition, along with that of Edgar Jones, was first seen largely to bolster special teams, but now they may have been just in time to help out with the line.
One way or another, the Cowboys are going to find out if they do have the depth to handle the new 4-3 defensive scheme.
