Sheffield United manager Danny Wilson raged at referee Steven Rushton after two red cards for his side during the 1-1 draw at Scunthorpe - and he insists he will appeal against them both.
However, Wilson was full of praise for his nine-man team who fought back to draw with an 83rd-minute equaliser from centre-back Neill Collins. That followed the dismissals of skipper Michael Doyle after just 15 minutes and midfielder Ryan Flynn in the 72nd minute.
"We have been asked not to criticise referees but it it difficult to accept that when you get a performance like we have seen here," fumed Wilson.
"It was an absolutely terrible game from this referee's perspective.
"First he has sent Michael off for an alleged stamp. But he got nowhere near their player, he was a foot away from making contact. And then in the second half the referee has sent off Ryan. It was a situation where both players were going for the ball hell for leather. It was a booking at best, but the sending off was ridiculous.
"Of course we will be appealing against each red card and I just hope that the referee realises the mistakes he has made. If he does that, then he will come out of it a better man. What he has done is spoil what could have been a very good match."
Scunthorpe manager Alan Knill was left frustrated not to get his first win of the season.
It seemed likely when new loan signing Leon Clarke headed the Iron in front on the hour mark, five minutes after coming off the bench.
"Leon is a good player. It has been a real struggle to find the strikers that we need, but Charlton have agreed to let him come here on loan," said Knill. "He and Karl Hawley, who we have also brought in, will make us stronger and competitive.
"I thought we played well against Sheffield United but they have one chance and the ball finishes in the back of our net. That's the way it is going for us at the moment. But there are plenty of positives to take from this performance."
