- Not to be confused with Rugby union.
Rugby league football, commonly known as rugby league in English-speaking countries and rugby 13/XIII in non-Anglophone Europe, is a full-contact sport played by two teams of thirteen players on a rectangular field measuring 68 m (74 yd) wide and 112–122 m (122–133 yd) long with H-shaped posts at both ends. It is one of the two major codes of rugby football, the other being rugby union.
