The Scotsman was given the charge on Thursday following his comments aimed towards the referee of the match between Chelsea and Sir Alex's side on Tuesday evening, Martin Atknison.
Ferguson expressed his displeasure after Atkinson failed to show Chelsea defender David Luiz a second yellow card, before awarding the Stamford Bridge side a penalty, from which Frank Lampard scored the game's winner, and then sent off Nemanja Vidic for a second bookable offence.
The 69-year-old vented to MUTV after the game: "You want a fair referee, or a strong referee anyway - and we didn't get that.
"I must say, when I saw who the referee was I feared it. I feared the worst."
The former Rangers player had until Tuesday to respond to the charge, but has decided to act quickly. However, a failed appeal may well lead to an extensive stay on the sidelines.
