West Ham are still to be charged by the Football Association - almost a month on from the riotous scenes that broke out during the 3-0 home defeat by Burnley.
The match at the London Stadium descended into chaos as disgruntled West Ham supporters staged four separate pitch invasions in the second-half, including one physical remonstration between captain Mark Noble and a fan.
Hundreds of supporters also rounded on the directors' box for an extended period of the second half and co-chairman David Sullivan was struck by a coin.
In October 2016, West Ham received an official warning from the FA following crowd trouble during their 2-1 victory over Chelsea in the EFL Cup.
