Neil Warnock has been charged with improper conduct for comments made earlier this month following a match against Bristol City.
Warnock slated the performance of referee Richard Beeby after he gave a penalty to The Robins three minutes from time and played five minutes of injury-time, which City scored in the last minute of, when he only signalled four.
Warnock told the after match press conference.
He said: 'I didn't think anybody should shake the referee's hand tonight if I am honest. I think they all wanted to talk to him the ones that did, I don't think they were shaking it with any loving care.
'The first half he played one minute and blew on the dot as we were attacking outside their box and then he puts four up in the second half and it's four minutes and 55 seconds when they score and they are attacking. I just think it is totally out of order.
'I thought the penalty was the one of the softest I have ever seen but it didn't surprise me on the evening.'
