On the sporting field, goalposts are posts between which players must carry, kick or pass a ball or similar object in order to score points, or simply a goal. In many games, at each end of the field of play, there are two vertical posts (or uprights) supporting a horizontal crossbar. In some games, such as Association Football or Hockey, the object is to pass the ball between the posts below the crossbar, while in others, such as those based on Rugby, the ball must pass over the crossbar instead.
