Terry has apologised for the language he used after announcing he will not challenge the ban and fine of £220,000 issued by an independent Football Association regulatory commission two weeks ago. Terry has not however apologised directly to Ferdinand.
Chelsea said in a statement they have taken further steps against their captain. The statement said: "Chelsea Football Club believes John Terry has made the correct decision by not appealing against the FA judgment relating to language he used at the QPR match last October."
The statement continued: "Chelsea also appreciates, and supports, John's full apology for the language he used. The club firmly believes such language is not acceptable and fell below the standards expected of John as a Chelsea player.
"The board has conducted its own investigation into the matter, and considered the various issues involved. The board has taken further disciplinary action in addition to the four-match suspension and £220,000 fine imposed by the FA. In accordance with our long-standing policy, that disciplinary action will remain confidential."
