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.
