Blackburn Rovers boss Steve Kean will investigate claims El Hadji Diouf taunted QPR's broken leg victim Jamie Mackie.
Diouf's behaviour infuriated the QPR players after Mackie fractured his right leg in two places during Saturday's FA Cup tie at Ewood Park.
Kean said: "At the time when he was on the ground nobody knew he had a broken leg.
"Hopefully whatever comes out will be the full story."
