Manchester City midfielder Gareth Barry has been banned for one match after admitting a Football Association charge of using abusive and/or insulting words to an official.
The 31-year-old "reluctantly" accepted the punishment after the charge arose from an incident after City's derby defeat to Manchester United on Sunday.
"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," said the FA's statement.
"Also as part of the standard penalty for this offence, Barry has been fined £8,000."
In posting the statement on their website City said "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."
Barry will be available for selection again for the home game against Reading on December 22.
Barry has started 15 of the last 17 matches both domestically and in the Champions League and plays a vital part in the defensive balance of the side.
Having lost to United, Mancini's side are now six points adrift of their nearest rivals and only four ahead of third-placed Chelsea.
They have taken five points from a possible 12 and need to get back to winning ways at St James' Park against a Newcastle team who have won just once in 10 matches.
