 Although both rugby codes are forms of football, in many places, it could cause confusion as "football" is understood to mean association football, gridiron football, Gaelic football or Australian rules football depending on the country (or indeed region of the country).In much of the rugby union-playing world, the sport of rugby league is infrequently played and rugby union is commonly known simply as "rugby"; in countries where both codes are played, there is a need to distinguish between the codes of rugby.In the United Kingdom, rugby union or rugby league fans rarely refer to their sport as "football" as in most cases this would refer to association football.
