Palace had wanted the game to be replayed but the Football Laegue have announced that this will not happen. "The referee's decision must be final," Football League chief operating officer Andy Williamson has said.
On Warnock's cheating comments, City boss Johnson said: "Cheating is not a very nice word to use especially when we had nothing to do with it except for being the opposition on this occasion.
"We knew the ball had gone into the net, but we got word the ref said there was an infringement so there is nothing more we can do.
"It happened to us twice last year and it is very disappointing and you have a little moan and you get on with it.
"I can understand Neil being disappointed but you have to choose your words these days.
"But nobody has cheated, nobody means to make mistakes and we had a perfectly good goal on the day ruled out for offside. That happens.
"It will happen to us many times and to Palace many times and you are aggrieved and you have got to get on with it."
