Cardiff manager Neil Harris has been charged by the Football Association after being sent off against Wycombe on Tuesday.
Harris was sent off nine minutes from the end of Cardiff's 2-1 loss at Adams Park, a third successive Sky Bet Championship defeat which has piled the pressure on the Bluebirds boss.
A statement on the FA Spokesperson Twitter account said: "Cardiff City FC's manager, Neil Harris, has been charged with a breach of FA Rule E3 following their EFL Championship match against Wycombe Wanderers FC on Tuesday.
"It is alleged that he used abusive and/or insulting language towards a match official in the 81st minute of the match. Neil Harris has until Wednesday (06/01/21) to provide a response.
Harris, who will be on the touchline when Cardiff visit Rotherham on Saturday, said at his pre-match press conference: "I have to respond to an FA charge by next week.
"So I have to look at the written report and respond to that."
