Mackie charged in for a tackle with Gael Givet and ended up with a broken leg, Diouf is then alleged to have verbally abused the player as he lay on the ground.
Never missing a chance to flap his lips, Neil Warnock had a go at the Senegal international via the press admitting that he "was going to call him a sewer rat but that might be insulting to sewer rats."
Now Mackie has had his fifty pence worth by telling the Sun newspaper: "I'm lying on the floor with a bad injury and even his team-mates were embarrassed by what Diouf was saying.
"There's no room for that in the game - and in my opinion he's an absolute disgrace.
"I'm trying hard not to think about Diouf. That's because when I do it makes me want to snap my cast off and run up there and find him.
"There's no place in football for the likes of Diouf. There's a line and he crossed it. Diouf was repulsive."
