The Black Cats will attempt to have Kevin Friend's decision to send off their defender during their clash with Stoke overturned, with their manager having already sought an apology
Sunderland eventually lost the game 2-0, having been forced to play much of the match with 10 men after Brown’s 36th-minute dismissal by referee Kevin Friend for a challenge on Charlie Adam.
Subsequent replays showed no obvious breach of the laws by Brown in the incident and Black Cats boss Gus Poyet went as far as to demand an official apology from the Referees’ Association in the game’s immediate aftermath.
A Sunderland spokeswoman said on Monday: "We have lodged our intention to appeal against the decision."
Former Premier League referee Dermot Gallagher has endorsed Sunderland’s plans to appeal by claiming that Friend did indeed get the decision wrong.
"I can keep this very short,” Gallagher told Sky Sports News. “We have to take it smack on the chin. The referee has lost concentration or not seen it.
"It is not a red card, that's all you can say. Brown's gone in hard but he's entitled to do that. As a refereeing body you have to take that smack on the chin."
