Aston Villa coach Kevin MacDonald has been charged with improper conduct by the Football Association.
The charge relates to Villa's match against Sunderland at the Stadium of Light on Saturday.
A statement from the FA read: "Aston Villa coach Kevin MacDonald has been charged by the FA for using language and/or behaviour amounting to improper conduct."
MacDonald, who was sent to the stand during the game, is alleged to have protested to the fourth official following what he deemed an unfair decision.
The 50-year-old has until Thursday to respond.
