Manchester United defender Rio Ferdinand was charged by the Football Association on Monday with improper conduct for comments about Chelsea rival Ashley Cole in a twist to the fallout from John Terry's racism trial.

Terry was cleared in court of racially abusing Ferdinand's brother, Queens Park Rangers defender Anton, while playing for Chelsea in a Premier League match last October.

Cole, who is black like the Ferdinands, appeared in court as a defense witness earlier this month. A day after the verdict, Rio Ferdinand appeared to endorse a tweet describing Cole as a ''choc ice,'' a slang term perceived as meaning black on the outside and white on the inside.

Ferdinand tweeted: ''I hear you fella! Choc ice is classic hahahahahaha!!''

Ferdinand later tweeted that it was ''not a racist term. It's a type of slang/term used by many for someone who is being fake.''

Cole said he didn't plan to complain. But Ferdinand, a former England captain, is now facing a fine or ban after being charged by the FA.

''The allegation is that the player acted in a way which was improper and/or brought the game into disrepute by making comments which included a reference to ethnic origin and/or color and/or race,'' the FA said in a statement.

Ferdinand failed to make England's squad for the European Championship squad in June and July, even after several defenders were ruled out because of injury. He has until Thursday to respond to the charge.

Terry is also the subject of an FA investigation after being charged by the governing body over the racism allegations he was cleared of at Westminster Magistrates' Court earlier this month.

Terry denies the charge, saying he only used the offensive term sarcastically to counter the profanity he claims Ferdinand was accusing him of using.
