Nottingham Forest manager Billy Davies confirmed the club will be appealing against defender Chris Cohen's first-half dismissal in the 4-1 defeat at Leeds.
Davies' assistant David Kelly was so incensed by referee Mark Halsey's game-changing decision, he refused to shake Leeds manager Simon Grayson's hand after the match.
Davies said: "I've spoken to our chief executive, Mark Arthur, and we're definitely intending to appeal the red card. Definitely."
He added: "We've seen the DVD and the referee said it was for excessive force, but I agree with our chief exec Mark and we'll definitely go to appeal and see how we get on."
"I said last week it (promotion) will not be decided until the last two or three games and you're better being a lucky manager than a good one at this stage of the season.
"Promotion will all be decided on refereeing decisions, suspensions, injuries and Lady Luck.
"They worked their socks off and I'm very proud of what my players gave us. You can't legislate for certain decisions that take place."
Grayson, who challenged his players to try and win all their remaining games this season before kick-off, felt Halsey was correct to send Cohen off.
He said: "The referee got it clearly right. I know Chris Cohen and he's not a malicious player, but he left the ground two-footed, caught George McCartney and the ball. It was the right decision.
"If it had been one of my players that had done that I would have accepted the decision. It was a reckless, not malicious challenge and the decision was correct."
