Chelsea defender John Terry has decided not to appeal against a four-match ban and fine of £220,000 for racially abusing QPR defender Anton Ferdinand.
Terry had until 6pm on Thursday evening to contest the sanction issued by an independent Football Association regulatory commission.
However, in a statement released via his representatives Elite Management, Terry said: "After careful consideration, I have decided not to appeal against the FA judgment."
He added: "I want to take this opportunity to apologise to everyone for the language I used in the game against Queens Park Rangers last October.
"Although I'm disappointed with the FA judgment, I accept that the language I used, regardless of the context, is not acceptable on the football field or indeed in any walk of life."
Terry's statement continued: "As I stated in the criminal case, with the benefit of hindsight my language was clearly not an appropriate reaction to the situation for someone in my position.
"My response was below the level expected by Chelsea Football Club, and by me, and it will not happen again.
"Looking forward, I will continue to do my part in assisting the club to remove all types of discriminatory behaviour from football. I am extremely grateful for the consistent support of Chelsea FC, the fans and my family."
Terry was found guilty by the independent FA commission of calling Ferdinand a "f****** black c***" during a Barclays Premier League match between Chelsea and QPR on October 23.
He has always maintained that he was merely repeating an accusation levelled at him by Ferdinand, but the commission found that his words were used as an insult.
