In rugby union, a kick that sends the ball through the opponents’ goalposts during open play is called a drop goal.
The kicker must drop the ball onto the ground and kick it as it rises. If the ball passes above the crossbar and between the goalposts, the team scores three points. Unlike a conversion, a drop goal can be attempted during normal play rather than after a try.
Drop goals are often used when a team is close enough to the posts for a realistic attempt, especially late in a close match. A successful kick can change the result immediately, which is why teams may use it as a tactical scoring option.
A penalty goal also scores three points, but it follows an awarded penalty and is taken under a different procedure. A conversion follows a try and is worth two points.
