West Ham and Tottenham have been charged by the Football Association with failing to control their players in Saturday's derby at London Stadium.
Spurs won the Premier League match 3-2 but almost squandered a three-goal lead.
The Hammers were pressing for an equaliser in stoppage time when a late melee involving several players occurred, prompting the charge.
Both clubs have until 18:00 BST on Thursday to respond to the charge.
A statement from the FA said: "It is alleged that in or around the 95th minute of the game, both clubs failed to ensure their players conducted themselves in an orderly fashion."
