Tottenham striker Mido has been charged with improper conduct by the Football Association after he was sent off in the defeat against Chelsea.
And his appeal against the red card, issued by referee Rob Styles for an elbow on Asier del Horno, was rejected, meaning he will serve a three-game ban.
The charge relates to his reaction to the dismissal for serious foul play in the White Hart Lane clash.
It is also centres on Mido's failure to promptly leave the field of play.
He has until 1800 BST on 1 September to respond to the charge and the case will be heard by a disciplinary commision on 9 September.
"The decision to send me off was very unfair, as I was only protecting myself and not elbowing the player," said Mido on his official website.
"The referee was about 25 metres away and instead of asking the linesman he was quick to show me the red card."
The 22-year-old, who is on loan from Italian club Roma, faces a three-match ban.
Mido added: "It was a normal collision, I went for the ball and even a yellow card is too much."
