The Hammers are expected to be receive a heavier fine than Millwall but despite the game being played away from The Den the club will be charged with offences ranging from racist chanting to the destruction and throwing of seats.
Both clubs are not expected to contest the charges but will ask for mitigating circumstances to be taken into account. West Ham are expect to be hit with a large fine but will not be asked to play games behind closed doors or be thrown out of the competition despite three pitch invasions and threats to the Millwall team.
One fan from South London was stabbed outside of the ground and several others were injured.
