In rugby union a scrum is a means of restarting play after a minor infringement. It involves up to eight players from each team, known as the pack or forward pack, binding together in three rows and interlocking with the three opposing teams front row. At this point the ball is fed into the gap between the two forward packs and they both compete for the ball to win possession. Teams can be penalised for intentionally causing the scrum to collapse, and for not putting the ball into the scrum correctly. A scrum is most commonly awarded when the ball is knocked forward, or passed forward, or when a ball becomes trapped in a ruck or maul. Because of the physical nature of scrums, injuries can occur, especially in the front row.

Rugby union football, commonly known simply as rugby union or more often just rugby, is a close-contact team sport that originated at Rugby School in England in the first half of the 19th century. Rugby is simply based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends.
