Chelsea captain John Terry has been banned for four matches and fined £220,000 for racially abusing Queens Park Rangers defender Anton Ferdinand.
Terry had denied an FA charge that he racially abused Ferdinand in a Premier League match last October, for which he was acquitted in a criminal case in July.
Terry's representatives, Elite Management, said in a statement released on his behalf: "Mr Terry is disappointed that the FA Regulatory Commission has reached a different conclusion to the clear not guilty verdict of a court of law.
"He has asked for the detailed written reasons of the decision and will consider them carefully before deciding whether to lodge an appeal."
An FA statement said: "An independent regulatory commission has today found a charge of misconduct against John Terry proven and has issued a suspension for a period of four matches and a fine of £220,000, pending appeal."
Terry was found not guilty in Westminster Magistrates Court in July of a racially-aggravated public order offence with the prosecution unable to prove he had called Ferdinand a "f****** black c***" as an insult.
Terry admitted using the words, but insisted he had only been repeating words he thought Ferdinand had accused him of saying.
The FA's decision to press ahead with their own charges infuriated Terry to the extent that on the eve of the disciplinary hearing he announced he was quitting international football with immediate effect, saying his position was "untenable".
Terry's legal team had argued the governing body's own rules dictated that his acquittal in court meant the case could not proceed but the FA believed their charge was distinct from the court charge.
The panel who handed Liverpool striker Luis Suarez an eight-match ban when they found him guilty of racially abusing Manchester United defender Patrice Evra last season declared at that time that simply using racist language was enough to constitute a breach of FA rules.
