Two of the matches will be suspended until the end of next season, while United boss Ferguson was also given a £20,000 fine by an FA regularity commission for suggesting Wiley "just wasnt fit enough" to officiate in the Barclays Premier League after last month's game.
Peter Griffiths QC, who chaired the commission, said: "Each member of the commission recognised Sir Alex Ferguson's achievements and stature within the game.
"Having said that, it was made clear to Sir Alex that with such stature comes increased responsibilities.
"The commission considered his admitted remarks, in the context in which they were made, were not just improper but were grossly improper and wholly inappropriate.
"He should never have said what he did say."
