Sunderland have confirmed they will appeal the red card shown to defender Wes Brown during Saturday's 2-0 defeat to Stoke.
The centre-back was controversially dismissed for a foul on Charlie Adam 36 minutes into the contest at the Britannia Stadium.
Brown appeared to make contact with the ball as he slid in to tackle Adam, who had opened the scoring on the half-hour.
Sunderland manager Gus Poyet was incensed by referee Kevin Friend's decision and the club has lodged an intention to appeal it.
Poyet said after the match: "I hope, maybe I am the first foreign manager to get a call this week from (referees' chief) Mike Riley.
"I know that Steve Clarke took a call last week. It happened at a key moment when we were trying to come back. We were then put down to 10 without explanation.
"If we take every danger out of the game then what do we do? You must then give a penalty for Asmir Begovic's challenge on Steven Fletcher in the second half."
Ex-Premier League referee Dermot Gallagher believes Sunderland's Wes Brown should not have been sent off.
And Gallagher says referee Kevin Friend made an error, telling Sky Sports News: "I can keep this very short. 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."
Friend has not been given a match for the next two rounds of Premier League games.
