Birmingham City Football Club has been charged with failing to ensure their fans behaved properly after the Aston Villa captain was assaulted during the derby.
The Football Association made the announcement this afternoon following the incident last Sunday, when a fan broke onto the pitch during the game and punched Jack Grealish.
Paul Mitchell, who is a Blues season ticket holder from Worcestershire, has since been jailed after pleading guilty to assault.
The FA statement reads: "Birmingham City FC has been charged with breaches of FA Rule E20 (a) and (b). It is alleged the club failed to ensure that its spectator[s] conducted themselves in an orderly fashion; refrained from improper or violent conduct and refrained from encroaching onto the pitch during the EFL Championship fixture against Aston Villa on Sunday [10/03/2019]. They have until 22/03/2019 to respond."
The FA also announced that Birmingham City and Aston Villa have both been charged with failing to ensure their players conducted themselves properly.
It follows a rash tackle from Birmingham midfielder Maikel Kieftenbeld on Villa captain Jack Grealish in the fifth minute, when players from both sides were involved in scuffles.
Both clubs have until Monday March 18 to respond, the Football Association said in a statement.
