Why is Slot not banned for Liverpool vs Aston Villa after red card?

Slot has landed himself in hot water with the Football Association for his sending off as the final Merseyside derby to be held at Goodison Park ended in chaos a week ago.

Slot has been charged for “allegedly acting in an improper manner and/or using insulting and/or abusive words and/or behaviour towards both the match referee and an assistant referee after the match had finished”.
Is Arne Slot banned for Liverpool’s trip to Aston Villa
As things stand, no. Slot has until Wednesday, February 19 (today) respond to his FA charge and any potential ban cannot be imposed in time for the Villa match.
This is because, as per the BBC, the charge is being treated as “non standard”, which means Slot does not have the opportunity to accept a set sanction without a hearing.
Therefore, after Slot has responded, the FA has three days to go back to the club and a hearing will then take place within 10 days.
Liverpool face Man City in another big game on Sunday and Slot is also likely he will be on the touchline for the trip to the Etihad Stadium – unless the process is fast-tracked.
