Middlesbrough have decided not to appeal against Mido's red card against Arsenal for his challenge on Gael Clichy.
The striker was sent off late on in Saturday's 1-1 draw at Emirates Stadium after catching Clichy in the head with a raised boot.
Boro had been contemplating an appeal against the three-match suspension, but have opted against challenging the decision.
Following discussions with match referee Mark Halsey and referees' chief Keith Hackett, Boro boss Gareth Southgate admits a successful appeal was unlikely.
Not very happy
"Having spoken to the referees' chief and to the referee himself, their feeling is that the decision wouldn't be altered," Southgate told the club's official website.
"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."
Mido, who has scored twice in 12 Premier League games this season, will now miss the upcoming matches against Derby County, Chelsea and Manchester United.
Boro's stance to accept the decision follows their last appeal against a red card, which was deemed 'frivolous', when Jeremie Aliadiere's ban was increased to four games after the striker was sent off at Liverpool.
