Aguero has been handed a three-match suspension after a charge of violent conduct against him from the Football Association was found proven.
He was charged retrospectively by the FA after appearing to elbow West Ham's Winston Reid in the second half of the Premier League game at the Etihad Stadium on August 28.
The incident, after which Reid was seen holding his neck, was missed by referee Andre Marriner and his fellow officials during the match.
The charge was issued after a review panel felt he should have been sent off, and was subsequently contested and rejected.
A statement from the Football Association 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 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."
