Ferguson was given a three game touchline ban by the FA on Thursday for being charged with with improper conduct aggravated by insulting and/or abusive language and behaviour towards Leicestershire based referee Kevin Friend.
The incident for which Ferguson was fined £4,000 happened in the tunnel after Preston's 4-3 defeat at Burnley on Saturday September 11th.
Ferguson was in the stand for the home defeat against Norwich and will not be allowed into the dug-out and technical area for Wednesday's League Cup tie at Wigan Athletic and Saturday's game at the Ricoh Arena.
