Mohammed Kudus will be suspended until December after being hit with an additional two match ban.
The West Ham star was shown a red card for a violent outburst against London rivals Tottenham last month.
After kicking out at and hitting Micky van de Ven in the face, Kudus knocked Richarlison down and shoved midfielder Pape Matar Sarr.
Kudus was initially shown a yellow card but it was quickly upgraded to red after a VAR review.
On top of the three match ban which would have seen him serve the final game of the suspension against Everton this weekend, Kudus will now miss games against Newcastle and Arsenal after the international break.
The Ghana international has also been fined £90,000, while his first game back will be away at Leicester City on December 3.
The former Ajax man, who has been one of West Ham's better players this season, accepted the charge and did not request a hearing with The FA.
However, the winger did offer mitigation having apologised and said he was "embarrassed" in a letter.
As part of the mitigation Kudus argued that his preparation had been "mentally and physically challenging" due to international duty and negative comments on social media.
West Ham have also been fined £30,000 for failing to stop their players behaving in an improper manner. Spurs were fined £20,000 for their part in the melee.
The FA statement read: "West Ham United and Mohammed Kudus have been sanctioned in relation to incidents during their Premier League fixture against Tottenham Hotspur on Saturday 19 October.
"It was alleged that the club failed to ensure their players didn’t behave in an improper and/or provocative and/or violent way around the 82nd minute.
"West Ham United admitted to this charge, and an independent Regulatory Commission subsequently fined the club £30,000.
"It was also alleged that Mohammed Kudus acted in an improper manner and/or used violent conduct after the offence that he was sent off for.
"The forward admitted to this charge, and he has been given a two-match suspension and £60,000 fine by the Regulatory Commission."
