Joey Barton has been banned for 12 matches and hit with a £75,000 fine after two charges of violent conduct were proven against him.
Barton was sent off for elbowing Carlos Tevez during the Rs' 3-2 Premier League loss at Manchester City, before he kicked Sergio Aguero and had to be manhandled off the pitch.
This eight-match suspension is to run consecutively to the four-game suspension Barton was already given for his dismissal in the fixture, making a total of 12 matches.
Barton accepted the charge of violent conduct against Aguero but denied the second breach of violent conduct against Kompany. The independent Regulatory Commission, however, found this second charge proved.
His dismissal came in his club's biggest game of the season, as they bid to avoid relegation to the Championship, having returned to the top flight for the first time in 15 years in 2011.
With the scoreline at 1-1, the the Rs had to play the majority of the second-half a man short, but took the lead through Jamie Mackie, until City's late comeback when them the title.
QPR however stayed up by virtue of Bolton Wanderers drawing 2-2 at Stoke City.
