After defeat to Hull City, Fulham defender John Pantsil reacted angrily to what he claimed was abuse, though it is unknown whether it came from fans or players.
Cottagers boss Roy Hodgson spoke to referee Mike Jones about the incident and is prepared to investigate further if Pantsil requests.
"The official said to me that John complained to him about being abused by somebody," said Hodgson. "The referee didn't hear anything so he couldn't take any action.
"It's unusual to see John quite that angry so something has obviously happened out there, but what it is I don't know.
"I'll investigate it with John. I wouldn't have thought he was abused by fans - if players got angry about that they'd be angry every time a game is played.
"I'll speak to John and hopefully he'll have calmed down. We shouldn't be making such a drama about it.
"But if John feels we as a football club need to do something about then we'll explore it."
