Nottingham Forest will appeal against the first-half dismissal of Chris Cohen during their 4-1 defeat at Leeds.
Cohen was given a straight red after referee Mark Halsey adjudged he used excessive force while winning the ball in a tackle with George McCartney.
"I've spoken to our chief executive Mark Arthur and we're intending to appeal," said Forest boss Billy Davies.
The match was goalless when Cohen was dismissed after 35 minutes, with his tackle sparking a melee.
Leeds boss Simon Grayson invaded the field of play to protest against what he thought was a dangerous challenge, while players and members of the coaching staff of both teams exchanged angry words.
It is a pity the game did not stay 11 versus 11 because we totally dominated

"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," said the Leeds boss.
"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."
Forest assistant boss David Kelly refused to shake Grayson's hand at the final whistle - and the Leeds boss added: "I'll always offer my hand to anybody - win, lose or draw - and if people refuse it, then that's their problem."
Davies would not be drawn on whether the Leeds boss and his backroom staff had influenced the referee.
"You decide for yourselves," added Davies. "You don't need me to tell you. We all know what took place.
"It is a pity the game did not stay 11 versus 11 because we totally dominated. We created many, many chances."
Two goals in quick succession from Jonny Howson and Luciano Becchio after the restart put Leeds in control before Garath McCleary pulled a goal back for the visiting side.
Grayson urges Leeds not to get carried away
Max Gradel scored twice to put the result beyond doubt as Leeds remained fifth in the table but Forest slipped out of the play-off zone and down to seventh.
Davies' team are now without a victory in eight games but the manager remained upbeat as he analysed his team's chances of winning promotion.
"I said last week 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," added the Scot.
"Promotion will all be decided on refereeing decisions, suspensions, injuries and Lady Luck.
"We did not deserve that today. Did we look like a side lacking in confidence? No. Did we look like a side that didn't have a work ethic? No."
