Manchester United's Rio Ferdinand has been found guilty of improper conduct and fined £45,000 by the Football Association for comments on Twitter, BBC News reported.

An independent commission concluded Ferdinand's response to a tweet describing Chelsea's Ashley Cole as a "choc ice" did not make him a racist.

But it was ruled the centre-half had brought the game into disrepute.

"The commission found that the breach included a reference to ethnic origin, colour or race," read an FA statement.

Ferdinand was also warned as to his future conduct. Manchester United have decided not to appeal against the decision.

The United defender tweeted: "I hear you fella! Choc ice is classic hahahahahaha!!" in response to a message from @carltonEbanks which stated: "Looks like Ashley Cole's going to be their choc ice. Then again he's always been a sell out. Shame on him."

The term relates to the black and white nature of a choc ice and can imply someone is being black on the outside and white on the inside,
