Ferguson was angry over Atkinson's failure to dismiss Chelsea defender David Luiz for fouls on Javier Hernandez and Wayne Rooney after he had already been booked.
He was further upset when Chelsea were awarded what he considered a "soft" penalty when Yuri Zhirkov fell under the challenge of Chris Smalling.
If Ferguson's suspended ban is triggered, he will be suspended from the touchline for United's FA Cup sixth-round tie with Arsenal at Old Trafford on 12 March and the Premier League game with Bolton a week later and then whatever extra games - if any - are added on for his latest outburst.
