Norwich and Sunderland have been charged by the Football Association for their conduct during Saturday's Premier League game at Carrow Road.
Players and coaching staff from both teams were involved in a heated clash during the first half of Sunderland's 3-0 victory between the two relegation rivals.
A touchline shoving match was sparked by Norwich midfielder Robbie Brady's challenge on DeAndre Yedlin, which saw the Sunderland player fall into an advertising hoarding in front of the Black Cats bench.
An FA statement read: "It is alleged that in or around the fourth minute of the fixture, both clubs failed to ensure their players and/or officials conducted themselves in an orderly fashion.
"Norwich and Sunderland have until 6pm on 21 April 2016 to respond to the charge."
The development follows further controversy elsewhere in the Premier League on a weekend in which Leicester's Jamie Vardy was charged with improper conduct following his red card against West Ham, whose striker Andy Carroll accused referee Neil Moss of trying to "even things up" by awarding Leicester a late penalty in Sunday's 2-2 draw.
