Mohammed Kudus has been charged with improper conduct following his red card against Tottenham on Saturday – leaving the forward at risk of an even longer ban.
Kudus saw red in West Ham's 4-1 defeat after lashing out at Micky van de Ven and Pape Matar Sarr in the closing stages of the game.
The forward was originally shown a yellow card by referee Andrew Madley, but this was upgraded to a straight red on VAR review.
Kudus aimed two kicks at Van de Ven while the defender was on the floor, then shoved the Spurs man in the face after he had got up to confront him.
Despite his team-mates' attempts to retrain him, Kudus then also pushed Sarr in the face.

The 24-year-old has now been charged with improper/violent conduct by the Football Association. A statement read: 'Mohammed Kudus allegedly acted in an improper manner and/or used violent conduct after the offence that he was sent off for.'
Violent conduct offences are a minimum three-game ban but Kudus risks having this increased if his respective charge is upheld.
The forward is guaranteed to miss games against Manchester United, Nottingham Forest and Everton. The Hammers then play Newcastle and Arsenal in their two fixtures after the international break.
West Ham and Tottenham have also been charged for failing to control their players.
The statement added: 'Tottenham Hotspur allegedly failed to ensure that their players didn't behave in an improper and/or provocative way around the 82nd minute.
'West Ham United allegedly failed to ensure that their players didn't behave in an improper and/or provocative and/or violent way at the same time.'
The two clubs and Kudus have until Thursday to respond.
Former Premier League referee Mike Dean had said after the game that Kudus could 'get done twice' for his two altercations.

'When you see the footage back, the first one he could have got sent off for, which hopefully he has,' Dean said.
'Hopefully the second one the FA will then take retrospective action so he'll get done twice in my opinion because he's hit two different players in the face on two occasions.'
Joey Barton was given a nine-game ban for three separate violent clashes when he was sent off for Queens Park Rangers against Manchester City in 2012.
