The Arsenal boss Arsene Wenger has been very outspoken in his criticism of the performance of referees lately, especially after Mike Dean's appalling decision on New Years Eve as well as other incidents this season.
'He was also fined £40,000'.
Wenger will have to watch from the stands as his team travel to Nottingham Forest in the FA Cup this Sunday, Chelsea in the Carabao Cup semi-finals next Wednesday and Bournemouth in the Premier League.
Mike Dean pulled up Calum Chambers for an alleged handball, which allowed Jay Rodriguez to convert from the spot and snatch a 1-1 draw for the Baggies.
However, that ban could yet be extended if the FA decide to extend the charge in the wake of his comments both before and after Wednesday's 2-2 draw against Chelsea.
Describing the incident, Wenger claimed that the decision was a "farce".
Not only that, the FA have asked for information on that too.
He has until 18:00 on Tuesday, January 9 to respond to the FA's request.
He followed that up after the Emirates thriller by saying: "A fantastic football game".
He said: "We got again a farcical decision and mentally we were shocked".
"We looked like we were mentally shot and could have lost the game - we had the resources to come back to 2-2".
"That's my opinion, but he will tell you he has seen it". We can spend all day talking about things that aren't important, but we want to see big games, with important players and see them refereed by top professionals. "I'm happy with the quality of our games".
