The NFLPA has filed a non-injury expedited grievance against the NFL to challenge the league's new personal conduct policy.

The union maintains that the policy is in violation of the collective bargaining agreement and seeks a cease and desist order to enjoin implementation of the policy.

In the grievance, the NFLPA emphasizes that "the NFL adopted the new Policy without the consent, and over the objections, of the NFLPA."

The NFL responded to the union's grievance in a statement Friday morning.

"The league's revised conduct policy was the product of a tremendous amount of analysis and work and is based on input from a broad and diverse group of experts within and outside of football, including current players, former players, and the NFL Players Association," the statement read.

"We and the public firmly believe that all NFL personnel should be held accountable to a stronger, more effective conduct policy. Clearly, the union does not share that belief."
