The Football Association has charged Queens Park Rangers captain Joey Barton with two charges of violent conduct following his dismissal against Manchester City on Sunday.
Barton was shown a red card for swinging an elbow at Carlos Tevez, but before he left the field he felled Sergio Aguero, went head to head with Vincent Kompany and had to be pulled away from Mario Balotelli.
The shameful scenes did not overshadow City's thrilling, last-gasp title success, but he is now facing the prospect of a lengthy ban after being charged by the FA.
"The FA has today [Monday 14 May] charged Queens Park Rangers midfielder Joey Barton in relation to two acts of alleged violent conduct during Sunday's match against Manchester City at the Etihad Stadium," read a statement on the FA's official website.
"Following the player's dismissal in the 54th minute of the fixture, there followed two incidents involving Manchester City's Sergio Aguero and Vincent Kompany.
"As Barton had already been dismissed, both of these incidents fell outside of the jurisdiction of the referee.
"Barton has until 6pm on Tuesday 15 May to respond to the charges."
