Incognito filed a grievance Thursday, Nov. 14, 2013, against the Dolphins over his suspension. A person familiar with the situation told The Associated Press that the guard filed it over his suspension for conduct detrimental to the team. The person spoke Thursday on condition of anonymity because the grievance has not officially been announced. (AP Photo/Wilfredo Lee, File)
