The official Cowboys roster on DallasCowboys.com shows the following players with specific injury/roster designations that are keeping them off the active roster:
Additionally, the Cowboys have the option of using the Reserve/Injured designation, which they used for the likes of Rico Gathers, Charles Tapper, and Brian Price last year, and can also use the Reserve/Non-Football Injury designation for players whose injury/Illness happened outside of the purview of the NFL.
Those designations will become an important roster management when the Cowboys have to reduce their roster to 53 players by September 1.
