A Premier League statement read: "The Premier League has received a complaint from West Ham United regarding certain comments made by a Fulham official and is currently looking into the matter."
Meulensteen confirmed on Tuesday night that a bid had been rejected by Upton Park officials for Morrison, though he remained hopeful about the prospect of an agreement being reached.
"We got knocked back," the Dutchman explained. "We will review it and move on. I've left it with (chief executive) Alistair Mackintosh.
"I've explained how I think about the situation so I have to wait and see."
When asked whether Morrison wants to join Fulham, he replied: "Yes."
