A case of mistaken identity was at the heart of referee Mick Russell's failure to send off Sheffield Wednesday's Jeremy Helan in today's derby with Huddersfield, Press Association Sport understands.
Huddersfield manager Simon Grayson described Russell's blunder in not sending off the midfielder, despite showing him two yellow cards, as "staggering", and called on the Football Association to introduce post-match press conferences for officials.
Helan was shown a first card for diving in the ninth minute and was then given a second for a 26th-minute foul on Adam Hammill.
However, Press Association Sport understands Russell had intended to book Helan's team-mate Michail Antonio for the initial offence, something which will be reflected in his report.
Grayson also fell foul of the confusion, believing the erroneous card was the second one and not the first.
"I think he's probably written the wrong number down in his book, which is staggering, and I also think he should have been helped by his officials, who should be overruling because they all know, when a referee makes a mistake like that, who he's booking," he said.
"The lineman should be helping out. He's not done it deliberately, but you can't make major mistakes like that.
"He's put (Michail) Antonio's number in his book, but he was nowhere near the incident. I don't mind referee's making big mistakes in terms of tackles and sendings off, but something quite simple like that shouldn't be happening in Championship football."
Amid the chaos, though, it appeared Town defender Anthony Gerrard understood what had happened.
Gerrard told Press Association Sport: "I didn't really notice to be honest. I thought he had booked two different players.
"I thought the first booking for the dive in the box was (Michail) Antonio and the second one was Helan, so I didn't concern myself with it.
"If he did make a mistake, so be it, it's just one of those things that can happen in football."
Wednesday manager Dave Jones had also got lost in the mess, believing Helan and not Antonio had been booked for diving.
"I don't know about a first booking, it was a penalty. That's the controversy," he said."Helan has been clipped and he's not the type of lad to do that (dive). I think we should have won the game, that's what I'm perplexed about."We should have had a penalty and we had the chance towards the end with (Mamady) Sidibe's header."Grayson admitted that having a man advantage would not have made his side certain winners, but asked for referees to explain their actions in future."I'm not going to say Wednesday going down to 10 men would have guaranteed us winning the game, but it would have certainly helped us and what if the lad had gone on to score or created the winning goal?" he said."It would have been a massive talking point, which it is already."I just think referees in general should be accountable for any decisions and have a press conference after the game, whether good decisions or bad decisions."It shouldn't be up to myself or Dave Jones to explain, they should be out and you (the media) should be able to ask questions as to why he made certain decisions."I've not seen Dave, but I'm sure if it was the other way round he wouldn't have been so calm and as placid on the touchline as he was."Speaking before the explanation of the incident emerged, former Football League official Tony Leake said he expects Russell to have to stand down for a period over his error, and believes a replay of the fixture is not out of the question.Leake told Press Association Sport: "The matter will now need to be dealt with by the relevant authorities. You cannot rule out the possibility of a replay."If Huddersfield won the game 3-0 I would not expect that to happen. But if Huddersfield believe the player being on the field meant the result did not go in their favour then it could be that the game is replayed."English referee Graham Poll famously booked Croatia defender Josip Simunic three times before showing a red card during their 2006 World Cup fixture against Australia.Following that error FIFA president Sepp Blatter indicated Australia could have demanded a replay had they lost and been knocked out.
