The Decatur Daily reports that Morgan County Chief Deputy Mike Corley says the charges against McClain mean his permit is invalid.
The former Alabama football star renewed his state pistol permit on Nov. 30, the same day he was allegedly involved in a confrontation that led to his arrest.
Police say he fired a gun by a man's head and is charged with assault, discharging a weapon in the city and other misdemeanor offenses.
A defense lawyer denies that McClain fired a gun, and he predicts the player will be acquitted. McClain's trial is set for Jan. 24 in Decatur municipal court.
