Within fifteen (15) business days following the completion of the investigation, or sooner if practical, the Executive Director of the NFLPA and the NFL Commissioner shall be advised of the status of the investigation and shall attempt to determine if a violation occurred and, if so, the proper disciplinary response. If the Parties are unable to agree upon whether or not a violation occurred, or as to the appropriate discipline, then either Party may immediately refer the matter to the Impartial Arbitrator (as established by Article 16 of the CBA).
