Reports suggest West Ham United and Millwall have been charged by the Football Association following the violence that marred last month's Carling Cup clash between the two teams.
No official announcement has been made but it is believed the FA will make their decision public on Monday.
It is understood that the Metropolitan Police were concerned that because the Lions face Leyton Orient on Saturday, which is close to Upton Park, any statement ahead of the match could worsen the situation.
One man was stabbed and several other people were injured after trouble erupted before the game and there were further incidents during and after the match, which the Hammers eventually won after extra-time.
Andy Williamson, the chief operating officer at the Football League, said of the problems that night: "We utterly deplore the violence that took place in the match.
"Such behaviour has no place within the game. We will work with the relevant authorities to ensure those behind it are held to count."
