Newcastle boss John Carver accused defender Mike Williamson of getting sent off deliberately in a blistering attack on his players after their 3-0 loss at Leicester.
Williamson was dismissed just after the hour when he collected a second yellow card for a late, knee-high challenge on Leicester's Jamie Vardy on the touchline.
He was followed off the pitch by Daryl Janmaat who was also sent off in injury time of what proved another dismal afternoon for the crisis-hit Magpies.
After eight successive Barclays Premier League defeats, Newcastle are nosediving towards relegation and Carver was furious after the final whistle at the King Power Stadium, with Williamson the prime target of his ire.
"I thought he meant it," Carver said in his post-match press conference. "When the ball went onto that left-hand side, my first reaction, five yards before making the tackle was, 'Don't do it' – and he did it.
"Vardy was off the pitch, Willo was off the pitch, the ball was off the pitch. There was no need to do it. I am not accepting that, especially in the situation we are in."
Asked why Williamson might have done something like that on purpose, Carver said: "I don't really know. It was just my thought when it happened. I thought he meant that and I have told him so. I have actually said this to his face."
Newcastle fell behind within a minute as resurgent Leicester, fully fired up and determined to maintain their survival charge, stole the ball from the kick-off and Leonardo Ulloa headed from a corner.
Wes Morgan added a second after 17 minutes and an Ulloa penalty put the result beyond doubt early in the second half.
Newcastle were booed off the field by their increasingly angry fans, some of whom held up a banner accusing the team of not trying. Some of the players were later jeered as "cowards" as they boarded the team bus on their way out of the stadium.
Carver, who has won just two of 16 games since succeeding Alan Pardew, said: "I can't disagree with them. I know some of them went over at full-time and the fans had a go, and more or less said, 'We don't want to see you'.
"If I was sitting in the stand with them I would be doing the same thing.
"We are a soft touch. We are a soft touch when the ball comes into the box because we are not prepared to put our heads on it.
"We can talk and talk – We need to grow up and we need to accept it. The ones that don't want to grow up and accept it can stay at home."
Newcastle have been locked on 35 points since February while Leicester, adrift on 19 points and seemingly doomed at the start of April, are now just a point behind them after five wins from six.
Carver said: "It is in our hands to do something about it. We have got to do something about it. The minute it is out of our hands then we are in trouble. I don't want to have to rely on anyone else."
Opposite number Nigel Pearson offered a word of sympathy for Carver, who was also the subject of fierce criticism from Newcastle fans.
Pearson said: "Whatever happens this season I can guarantee John Carver will have done everything in his power to make sure things are right for Newcastle United. He is a pretty selfless man."
Newcastle's capitulation arguably took the attention away from Leicester's superb performance, which was fueled by a passionate crowd.
In such form they are heading towards safety although Pearson is taking nothing for granted, noting his side are still below Newcastle.
He said: "We have a more realistic chance than we did before we kicked off today. Newcastle are having a difficult time but they have still got one more point than us at the moment.
"Momentum is important but off the back of a defeat in midweek – had we not got this result, then again (you can find) things can change quickly. We have given ourselves a better chance.
"The result is the most important thing but the performance I thought was very good."
Pearson himself has had a difficult week after putting himself in the spotlight with his bizarre 'ostrich' confrontation with a journalist following the Chelsea loss on Wednesday.
He later apologized but a further exchange with a different reporter on Thursday kept the matter in the news.
He said: "If I make an apology, I make an apology based on what I think is the right thing to do. There is no smoke and mirrors on that.
"What I do and what I am is what I am and I have to live with that, and I don't necessarily want to change.
"But we all learn from what we do, good and bad. I don't see too much mileage in going much further with that.
"It was important to get back to winning ways today. Anything else, side issue-wise, is not really as significant."
