Manchester City midfielder Gareth Barry is to serve a one-match ban for using "abusing and/or insulting words towards a match official" following Sunday's 3-2 defeat to Manchester United.
Barry will now be unavailable for the Premier League encounter at Newcastle United on Saturday after he and City "reluctantly" accepted the decision.
An FA statement read: "Manchester City's Gareth Barry will serve a one-match suspension with immediate effect after admitting a breach of FA Rule E3 in that he used abusive and/or insulting words towards a match official following his side's match against Manchester United on Sunday 9 December 2012.
"Also as part of the standard penalty for this offence, Barry has been fined £8,000.''
Had Barry appealed the decision, he would have been liable to face a two-game ban.
City added on their official website: "Both the club and Gareth Barry reluctantly accept the punishment which leads to Gareth being unavailable to take part in the weekend's match against Newcastle. He will return to first-team action against Reading on 22 December."
City may also be without captain Vincent Kompany for the trip to Newcastle after he limped out of the derby defeat with a hamstring injury.
