However, the 29-year-old has been found guilty on both charges at a personal hearing by an Independent Regulatory Commission.
"There are rules of conduct that should be adhered to, and such behaviour tarnishes the image of football in this country, particularly as this match was the pinnacle of the domestic season and watched by millions around the globe," said the chairman of the commission.
Four games of the ban are from the initial sending off, while another eight matches have been added because of the subsequent incidents. He has also been fined £75,000.
The ban will begin at the start of next season.
