Watford and Stoke have been charged with failing to control their players by the Football Association.
Stoke's 1-0 win at Vicarage Road on Saturday came to a bad-tempered conclusion with two separate incidents involving players from both sides squaring up to each other.
First, Watford's Abdoulaye Doucoure and City's Mame Biram Diouf were booked after they scuffled on the touchline three minutes from full-time.
Then, in stoppage time, Hornets skipper Troy Deeney sparked a second melee when he grabbed the face of Stoke midfielder Joe Allen.
That flashpoint came after Stoke had put the ball out of play with a player down injured, but rather than pass the ball back Deeney attempted a cross into the visitors' penalty area.
