Sunderland manager Gus Poyet has been charged with improper conduct by the FA following his dismissal after clashing with Hull boss Steve Bruce during Tuesday's 1-1 draw.
Poyet's sending off by referee Mike Dean came as a result of an on-pitch incident involving Jack Rodwell, who had just been cautioned for simulation. Poyet believed Sunderland should have been awarded a penalty, while Hull boss Steve Bruce claimed Rodwell dived.
The two managers then clashed as Poyet was making his way to the stands, with hosts Hull leading 1-0 at the time. The Uruguayan walked over to shake hands with Bruce, who had to be restrained by officials after appearing to react angrily.

A statement on the FA's official website read: "Sunderland manager Gus Poyet has been charged by the FA following the game against Hull City on March 3, 2015.
"It is alleged that his behaviour in the 35th minute of the fixture amounted to improper conduct. He has until 6 p.m. on March 9 2015 to respond to the charge.
"Meanwhile, Hull manager Steve Bruce has been contacted by the FA in relation to the same incident and formally reminded of his responsibilities."
Poyet told BBC's Match of the Day following the draw at the KC Stadium: "I was sent off for kicking the bucket. The bottles coming out of the bucket didn't help me.
"I know it doesn't look good but it's nothing to worry about. I prefer that than saying something I would regret. I'm old fashioned. What happens on the pitch stays on the pitch. There are no problems for me at all."
He added: "In football things happen. I have to convince the officials not to put any buckets of drinks around me. I have no regrets whatsoever."
Poyet and Bruce shook hands in a KC Stadium corridor after seeing goals from Dame N'Doye and Rodwell cancel each other out, but there was plenty of simmering resentment beneath the surface.
"I've spoken to Steve and shaken hands. I just saw him, nothing happened. It's football. It's passion," Poyet said. "I have to convince the officials not to put any buckets of drinks around me. I have no regrets whatsoever. If that is a bad image for football I am sorry but I don't think it's something to worry about."
Poyet was at least clear that Rodwell was the victim of inconsistency from referee Dean, suggesting Paul McShane had won a free-kick in similar circumstances to Rodwell.
"I was not happy with the decision of McShane. He was diving like he was in a theatre, dancing, ballet and then he got a free kick for Hull.
"And then Jack was diving and got a yellow card and free kick against him. So give me one, you cannot get both against you.
"McShane, in the first half, jumped with both feet and went down like he had been shot, but he won a free kick. I was just asking for the same treatment, simple as that."
Bruce, who has been reminded of his responsibilities by the FA, said: "The big contentious issue is Jack Rodwell running through and then from where I was standing he dived and the referee called it right.
"From Gus' reaction he thought it was wrong. You have to ask him why he came over to myself. I don't know what I was supposed to have done.
"These things happen in the heat of the moment. Grown men acting like a couple of children. They happen in big games. I don't mind being accused. I suppose I'm not flavour of the month. Let's go and have a glass of red."
