Middlesbrough have decided not to appeal against the sending-off of Egypt striker Mido during the 1-1 weekend draw at Arsenal.
Mido was shown a straight red card for catching Gael Clichy in the face with a high boot just minutes after coming on as a substitute at the Emirates Stadium.
Both managers felt that Mido had been harshly treated, but Boro have opted not to appeal the decision after talking to match official Mark Halsey.
Manager Gareth Southgate told the club's official website: "Having spoken to the referee's chief and to the referee himself, their feeling is that the decision wouldn't be altered.
"Whether or not there is intent is no longer considered, it's about whether a challenge puts the opponent in danger.
"At no time has anybody suggested Mido intended to do what he did, but unfortunately it is perceived as dangerous play because he caught the lad.
"We're not very happy about it but I can see why the referee has sent the lad off under those rules. But a three-match ban is very harsh."
Southgate had spoken up for his player straight after the game, with Gunners manager Arsene Wenger also feeling that Mido was unlucky to be red-carded.
He added: "Funnily enough I didn't think there was any intention there from Mido.
"I believe the referee gave the red card when he saw the injury, because he was bleeding on the top of his head, but it was very difficult to assess that he wanted to hit him on his head, I don't think so."
