Stoke City winger James McClean was targeted by sectarian chants during the Potters 5-2 win at Huddersfield.
There was a tannoy announcement in the second half of the game at the John Smith's Stadium saying "racist chanting is affecting the game and will not be tolerated".
However, it is understood the abuse Huddersfield are investigating is of a sectarian nature.

Stoke City head of media and communications Fraser Nicholson said: "Just to provide some context for that, James McClean is being encouraged to report abuse that he receives that's of a sectarian nature to the match official.
"He did it on Boxing Day when he was subjected to it by Sheffield Wednesday fans and obviously felt the need to do it again."
The referee stopped play in the 64th minute to inform both managers that McClean had reported abuse from the crowd.
Stoke boss Michael O'Neill added: "It's clearly the things that were said were of a sectarian nature and there's no need for that, there's no need for that in any stadium.
"James is obviously a player that is particularly targeted for this and has been consistently. I think he is right to bring it to the attention of the referee, I fully support him in that, why should James have to suffer that every time he goes and takes a corner kick.
"This is not something we want to see in football grounds, its unnecessary and for me James is 100 percent right in what he did. People have to be held accountable for their behaviour when they come to a stadium.
"It's not something we want to be consistently talking about - sectarianism or racism or whatever.
"We want to be talking about the game because there was seven goals here."
Huddersfield manager Danny Cowley added: "There's no place for discrimination of any type whatsoever.
"I'm sure the club will investigate this and make sure the people involved in it are duly punished."
