Anton Ferdinand has been targeted with racist abuse via his Twitter account.
The Football Association are investigating claims that QPR defender Ferdinand was the subject of a racial slur by Chelsea and England captain John Terry on October 23.
Ferdinand released a statement yesterday saying he had "strong feelings" on the matter and backed the FA's inquiry.
This morning, Ferdinand retweeted messages of support sent to him - but also a shocking racist jibe at him that appears to be from a Chelsea fan.
Ferdinand has submitted an account of his exchange with Terry during QPR's 1-0 win over Chelsea to the FA, and said in a statement: "I have very strong feelings on the matter, but in the interests of fairness and not wishing to prejudice what I am sure will be a very thorough inquiry by the FA, this will be my last comment on the subject until the inquiry is concluded."
Terry has denied racially abusing Ferdinand, who he admitted had accused him of making a racist remark, but insisted his own response was actually a denial and not racist in any way.
Chelsea refused to allow questions from journalists about the saga in yesterday's press conference in Belgium ahead of their Champions League match against Genk.
Terry, who has had a turbulent 18 months off the pitch, could find himself losing the England captaincy for the second time in his career if he is found guilty of racially abusing a fellow footballer on the pitch.
