Everton will appeal against the controversial red card given to Dominic Calvert-Lewin in Thursday's FA Cup third-round draw with Crystal Palace.
The striker faces a three-match ban having been dismissed for a sliding challenge on Nathaniel Clyne following a VAR review during the second half of the 0-0 stalemate.
Referee Chris Kavanagh initially did not even give a free-kick but was sent to review the incident on the pitchside monitor and decided the contact was enough to dismiss Calvert-Lewin.
The decision was widely criticised and a Toffees statement read: "Everton Football Club has today notified the FA of its decision to appeal the red card issued to Dominic Calvert-Lewin in our FA Cup third round fixture at Crystal Palace on Thursday evening."
Everton manager Sean Dyche said he remained a fan of VAR but that the system was "beginning to test my patience".
"I look at the obvious offsides, which I think is fair, that should be there," said Dyche. "Some of the others I’m going, 'Well, what’s got a chance now of being let play and what’s got a chance of being called’, but we don’t actually know."
If the decision is not overturned, Calvert-Lewin faces missing the third-round replay as well as Premier League matches against Aston Villa and Fulham.
After the game, Dyche called for a "tidying up" of VAR following the controversial decision in the goalless FA Cup third-round tie at Crystal Palace.
Nathaniel Clyne went down wincing following a sliding tackle by Calvert-Lewin, who appeared to catch the Palace defender's shin with his studs.
Referee Chris Kavanagh went to review the incident on the pitchside monitor and decided the contact was enough to dismiss the Toffees striker, who was sent off for the first time in his career.
Dyche said: "It seems a bit confused at the moment. I said recently, we had another one, where I said I don't know who is refereeing which. I am a fan, (but) I definitely think we're all aware it needs tidying up.
"I thought it was getting tidied up, and then it seems to have stepped back a bit. I remain a fan at this stage, but it is beginning to test my patience."
Dyche had lamented the decision to turn to VAR in the first place, suggesting the calls throughout the contest had perhaps been inconsistent after an Everton penalty shout went unanswered.
He told ITV: "If you want to slow-mo everything, then you have got to slow-mo everything - you can't just have it one for one and one for the other.
"At the end of it is minor contact. In live time, he doesn't give everything, then you slow it down - and everything looks worse on slow-mo, we all know that."
Palace boss Roy Hodgson could understand his counterpart's frustration, but stopped short of criticising the decision to dismiss Calvert-Lewin.
He said: "I mean Sean comes from a type of football, was brought up in a type of football where those sort of challenges were pretty commonplace and they weren't punished if people got the ball.
"We now live in a slightly different world I think, and that is if you go into challenges with a straight leg and you have a bit of intent behind it, there's a risk.
"There was definitely no malicious intent from Calvert-Lewin, there's no question of that, not from seeing it back, it's just a situation of an interpretation these days of a challenge, and the interpretation unfortunately can be that if you're straight-legged and your foot is off the ground as you go into a challenge it can be deemed a red card.
"So have I got sympathy for him? Yes I have."
