Norwich and Cardiff have been charged by the Football Association for a confrontation between some of their players during Saturday's 0-0 draw, reports BBC Sport. The teams have been accused of failing to ensure their players conducted themselves in an orderly fashion.
The scuffle in added-on time came after Canaries midfielder Leroy Fer attempted to score from a throw-in when Cardiff had put the ball out for an injury.
Both clubs have until 18:00 GMT on 4 November to respond to the charge.
