Queens Park Rangers captain Joey Barton was on Wednesday evening banned for 12 matches and fined £75,000 by the Football Association after being charged with two acts of violent conduct.
The punishment came as a consequence of his dismissal for elbowing Carlos Tevez on the final day of the Premier League season at Manchester City.
Barton kneed Sergio Aguero, sending the striker to the ground, and attempted to headbutt City captain Vincent Kompany before being ushered off the field.
The midfielder accepted the charge relating to Aguero, but denied the one against Kompany and requested a personal hearing, where the verdict went against him.
