NFL Collective Bargaining Agreement

Article 44
Injury Grievance

Section 2

Any player and/or the NFLPA must present an Injury Grievance in writing to a Club, with a copy to the Management Council, within twenty-five (25) days from the date it became known or should have become known to the player that his contract had been terminated. The grievance will set forth the approximate date of the alleged injury and its general nature. If a grievance is filed by a player without the involvement of the NFLPA, the Management Council will promptly send copies of the grievance and the answer to the NFLPA.
