Several Hammers players crowded the referee Mark Noble's sending off.
The charge relates to the aftermath of Mark Noble’s sending off, where several Hammers players crowded referee Kevin Friend in protest.
Noble’s dismissal was harsh, to say the least, and has since been overturned, meaning he is free to return to action in West Ham’s next game against Newcastle on September 14th.
The club has until 6pm on September 7th to respond to the charge and will likely be aggrieved at the FA's decision.
The Hammers have had a tough time on the disciplinary front this season and have failed to keep their full quota of players on six separate occasions already, leading Winston Reid to call for greater restraint from his team-mates.
The likely outcome is a fine rather than any ban for anybody, but it is still a matter the club could do without having to respond to.
