Sergio Aguero has been handed a three-match ban for his elbow on Winston Reid in the 3-1 win over West Ham on Saturday.
The incident left the New Zealand international dazed and he was subsequently replaced by Jonathan Calleri.
Manchester City denied the charge levelled against the player and requested a lenient sentence.
But a Football Association statement revealed the player will now miss his club’s next three fixtures, starting with Manchester United ahead of another Premier League clash with Bournemouth, and the English Football League cup match with Swansea.
The statement read: “Sergio Aguero will serve a three-match suspension with immediate effect after an FA charge of violent conduct against him was found proven.
“The Manchester City forward was involved in a 76th minute incident with West Ham United’s Winston Reid on Sunday [28 August 2016], which was not seen by the match officials but caught on video.
“The club denied the charge and submitted further that if it was to be found proven, the standard punishment would be clearly excessive.
“On finding the charge proven at a hearing today [Friday 2 September 2016], an Independent Regulatory Commission went on to reject the club’s further claim to decrease the three-match ban.”
