A drop goal is a method of scoring points in rugby union and rugby league, and also, rarely, in American football and Canadian football. It is scored by drop-kicking the ball (dropping the ball and then kicking it as it touches the ground) over the crossbar and between the goalposts. After the kick, the ball must not touch the ground before it goes over and through, although it may touch the crossbar or posts. A drop goal in rugby union is worth three points, and in rugby league, it is usually worth one point. There are four main ways to score points in rugby, including a try, penalty, conversion, and drop goal. A drop goal is scored during the course of play where the player drops the ball to the ground and kicks it as it touches the ground. If the drop goal attempt is successful, play is restarted with a kickoff by the team that conceded the goal.
