Nottingham Forest and Derby County have been charged by the Football Association.
The charge comes after skirmishes broke out between players in the 96th minute of Saturday's East Midlands derby, as well as after the final whistle was blown by referee Tim Robinson.
In a statement, an FA spokesperson said: "Nottingham Forest FC and Derby County FC have been charged with two breaches of FA Rule E20.1 following their EFL Championship match on Saturday 22 January 2022.
"It is alleged that the clubs failed to ensure their players conducted themselves in an orderly fashion in both the 96th minute and following the final whistle. Nottingham Forest FC and Derby County FC have until Monday 31 January 2022 to provide their respective responses."
Former Premier League referee Keith Hackett predicted the charge earlier this week, saying: “The Football Association will charge both clubs for failing to control their players."
Referring to the Rams' financial troubles, he added: “That’s the last thing that Derby County want. A simple thing like that could be a heavy fine.
“When they are short of cash, it can lead to other things. The whole scenario that surrounds Derby County is horrendous and could follow the path of Bury.”
On the scenes after full-time, Derby boss Wayne Rooney told the media: "It is an emotional game, a local derby.
"I know players get frustrated when they feel it is the wrong decision against them, but I am fully with him [Morrison], and the players, I support them.
"Of course we need to behave in the right way, but it shows the players are fighting and care, and that they are giving everything to try and help this club."
