A person familiar with the situation tells The Associated Press that Richie Incognito has filed a grievance against the Miami Dolphins over his suspension.
The person spoke Thursday on condition of anonymity because the grievance has not officially been announced.
Incognito, a guard, was suspended by the team Nov. 3 for misconduct related to the treatment of teammate Jonathan Martin, who abruptly left the Dolphins late last month to receive help for emotional issues.
The NFL is investigating whether Incognito harassed or bullied Martin. Incognito has said the conduct was all part of the normal locker room environment.
ESPN first reported the grievance.
