The Football Association are to investigate further claims of racism against Newcastle midfielder Emre.
The FA's disciplinary team are to follow up a statement from Watford midfielder Al Bangura after looking into reports that he was allegedly abused by Emre, but Bolton forward El Hadji Diouf will not be pursuing a similar claim.
An FA spokesman said: "Following the allegations which appeared in the media of alleged racist incidents involving Emre, The FA wrote to El Hadji Diouf and Al Bangura to ask them if they were able to provide statements.
"El-Hadji Diouf has responded and confirmed he does not want to pursue the matter.
"Al Bangura has responded with a statement and further investigations will now be made."
Emre is currently awaiting a hearing date after denying an FA charge of using racially-aggravated words and/or behaviour during the defeat at Everton at the end of December.
