Emmanuel Adebayor will miss the Manchester derby after not appealing the violent conduct charge lodged against him by the Football Association.

Adebayor had until 6pm to respond to the charge and in accepting it, has effectively condemned himself to a three-match ban.

The FA's disciplinary panel will formally sit in judgement on Thursday. But the punishment for such offences is automatic and it seems unlikely there will be any change in that stance.

City knew there was little point in contesting the case once referee Mark Clattenburg confirmed he would have sent Adebayor off if he had seen the Manchester City forward's challenge on Robin van Persie.

The Dutchman sustained a cut to the head and launched a fierce attack on his former team-mate, who he claimed had acted in a "malicious" manner.

Arsene Wenger weighed into the debate as well on Tuesday, and with wider opinion lined up against him, it was futile for Adebayor to take the matter further.

City have another few days before they decide whether to contest the improper conduct charge brought against Adebayor for his ill-advised goal celebration in front of the Gunners' supporters at Eastlands.

Although Manchester United's Gary Neville was fined £5,000 for a similar offence in a match against Liverpool at Old Trafford in 2003, the FA do have the power to suspend players for such behaviour.

And, as both Premier League chief executive Richard Scudamore and FA counterpart Ian Watmore have both spoken out against the reaction, which left the Greater Manchester Police fuming, leniency cannot be guaranteed.

Providing the FA confirm a three-match ban tomorrow, Adebayor will miss the encounter with United on Sunday, the Carling Cup tie with Fulham next Wednesday and a Premier League meeting with West Ham on 28 September.

Any additional suspension would start with the trip to Aston Villa, which would rule Adebayor out of domestic action until 18 October, when City travel to local rivals Wigan.

It leaves City boss Mark Hughes facing a striker crisis this weekend, with only Craig Bellamy of his front-line forwards likely to be available.

Robinho, Roque Santa Cruz and Benjani have already been consigned to the injured list and Carlos Tevez is rated extremely doubtful to face his old club.

In addition, City had a scare over Micah Richards earlier this week when the young defender was forced to miss two days' training after going down with a bout of tonsillitis.

Thankfully, Richards' symptoms have now eased, which should allow him to face Alex Ferguson's men, along with Stephen Ireland, who is optimistic about his recovery from an ankle injury that forced him to be replaced at half-time in Saturday's win against Arsenal.
