Manchester City could find themselves without the services of Sergio Aguero in their upcoming matches. The player has been charged with violent conduct after an alleged elbowing incident against William Reid in City’s league match against West Ham United on Sunday.

Manchester City won 3-1 against West Ham, but the incident between the two players could mean that Sergio Aguero will be missing the upcoming Manchester Derby and two other matches. The much-awaited derby against Manchester United has been scheduled to be played on Sept. 10. According to Give Me Sport, if Aguero receives the customary three-match ban associated with such charges, he won’t be making an appearance at the crucial game.

The English Football Association has assigned a three-man panel who will review the case. Aguero allegedly elbowed Reid in the second half of the match at the 76th minute. Referee Andre Marriner was in charge, but the FA has decided to review the incident and impose retrospective action, if need be. The statement declares that match officials did not see the incident clearly, but everything was caught on video.

“Each panel member will review the video footage independently of one another to determine whether they consider it a sending-off offence. For retrospective action to be taken and an FA charge to follow, the decision of the panel must be unanimous,” read the official statement. The identity of the members of the panel has remained anonymous and were described only as “former elite match officials.”

Sergio Aguero has been given until Wednesday, Aug. 31, to respond to the allegations. If he is found guilty, Pep Guardiola would have to devise a way to make do without their star player in the upcoming games. Manchester City will be facing Bournemouth and Swansea aside from the Manchester Derby.
