QPR manager Neil Warnock has labelled Blackburn's El-Hadji Diouf "a gutter type" and claimed the Senegal international verbally abused Jamie Mackie while he lay on the pitch with a broken leg.
Mackie suffered a double fracture in a challenge with defender Gael Givet which saw both players leave the field on stretchers during Blackburn's 1-0 FA Cup third round victory at Ewood Park.
"He's broken both bones, his tibia and his fibula, and he's gone to hospital but will travel home with us," Warnock said. "The lads were furious with El-Hadji Diouf; he (Mackie) had broken his leg and he is calling him all sorts on the pitch.
"There was no need to put the finger up and call him a disgrace and even the Blackburn people were embarrassed. I can't abide people like that, I don't know why he wants to take on the world every week.
"For many years I have thought he (Diouf) was the gutter type - I was going to call him a sewer rat but that might be insulting to sewer rats.
"I think he is the lowest of the low and I can't see him being at Blackburn much longer because I can't see Steve Kean putting up with someone like that in the dressing room when he is trying to form a new image for Blackburn.
"I think he will be the first to go and good riddance - I hope he goes abroad because I won't miss watching him. He is a nasty little person."
Warnock fears Scottish international Mackie will miss the rest of the season but he attached no blame to Givet for the challenge.
"It was not a malicious tackle but it is his standing foot and you can see in the slow motion his leg bends. It is disappointing for everyone and the result pales into insignificance. I'm pulling my hair out because I didn't want to play him but he pleaded with me to play yesterday - that's how he is, he wants to play in everything.
"We will miss him, it is a massive blow because I can't see him playing [again] this season. I didn't want to play [Adel] Taarabt because I thought he would break his leg - those were the words I used, ironically."
Blackburn boss Steve Kean revealed that Givet may return in time for Rovers' clash with Chelsea next weekend.
"He has a badly swollen knee so we don't know the extent of that but the doctor is hopeful that will be okay for the Chelsea game," Kean said. "Hopefully the lad (Mackie) is okay and can make a speedy recovery.''
Rovers finally took the lead through David Hoilett in the 76th minute after missing a host of chances.
"We felt as though it could have been one of those games where we got many chances early on and each time you miss it gives the opposition a little bit of confidence.
"Fortunately enough Junior Hoilett popped up with a good goal, rounding off a good display.''
Kean also revealed that Blackburn's ambitious plans to sign AC Milan's Ronaldinho had failed.
"I think that looks like that is dead in the water. It looks like he is going to go back to Brazil. We followed that right through as much as we could but it looked like it was on the back foot, then it came alive and now it is totally finished now from what I've been told."
