A furious Steve Morison branded one fan's behaviour "an absolute disgrace" after he claimed vile abuse was hurled towards Cardiff City's 65-year-old club doctor during the match with Sheffield United.
During the first half of the match with the Blades, Morison and his assistant Mark Hudson were seen talking to a member of Bramall Lane's security after Bluebirds wing-back Cody Drameh had just received treatment for a knee injury by Len Nokes, the club's chief medical officer.
The Bluebirds' coaching staff members singled out a supporter in the crowd, however it was difficult to ascertain the root cause of the issue. However, after the match, which they lost 1-0, Morison alleged that what the supporter was shouting towards Dr. Nokes was unacceptable.

"It's amazing how some people are allowed to talk to you and talk to someone like Len Nokes, who has been at this club for 30-odd years. Someone talks to him like that? Obviously I can't say what they said to him but it just shows a complete lack of respect," he said after the match.
"When asked to sort it out, because you can see the culprit, nothing gets done. 'Oh, he's been spoken to', well, he carried on for the rest of the game. Imagine I had said that? I think it's an absolute disgrace.
"But it is what it is and that's football. You're allowed to say what you want to us but we can't say anything back because we are the professionals. It's an absolute disgrace, what they said to him. An absolute disgrace.
"They heard it, everyone knows who it was, but he was allowed. I maybe should have said it was racist, because then they would have gone and done something. But it was an absolute disgrace, he is an old man, a doctor, looking after a player on the pitch. And they talk to him like that? Totally wrong.
"And when they know who it is and they let him carry on and sit there for the rest of the game, because it's easier to do that, and we wonder why we've got problems in the world. It's a disgrace."
Cardiff suffered their third straight league defeat on Saturday afternoon after Iliman Ndiaye scored the only goal of a toughly-fought game.
But Morison was heartened by how his players performed up in Yorkshire, saying the encounter was a positive experience in all for a side who are transitioning.
"Nothing negative coming from me today," he added. "That was excellent from our lads. We limited a top, top team to their least amount of shots this season at Bramall Lane.
"We had just as many chances as them, we could have easily been in the lead. We could have been level or come away with something, but we haven't.
"We are a team in transition. I am really proud of that [performance]. I thought we played really well, it's just they took one of their five chances and we didn't take one of ours, so I am frustrated from that point of view. But they are a top team and fighting for the play-offs.
"You could see their reaction after the game, they were desperate for that game to finish. I really enjoyed standing there and watching the players carry out what we asked them to do.
"The changes at half-time maybe killed us a little, because people were not in the game where others were. Ultimately, that's maybe cost us in the end.
"It was an average age of 23 when we left that football pitch today, but it shows just where we are. There were £2m worth of transfer fees [on the pitch for Cardiff], whereas they've got over £30m. So it's something to be proud of for our football club."
