First XV

Rugby union is a team sport played between two teams of fifteen players. It is known for its rich terminology.

This is a general glossary of the terminology used in the sport of rugby union. Where words in a sentence are also defined elsewhere in this article, they appear in italics.

89

An "89" or eight-nine move is a phase following a scrum, in which the number 8 picks up the ball and transfers it to number 9 (scrum-half).

99

The "99" call was a policy of simultaneous retaliation by the 1974 British Lions tour to South Africa, (the 99 comes from the British emergency services telephone number which is 999). The tour was marred by on-pitch violence, which the match officials did not adequately control and the relative absence of cameras compared to the modern game made citing and punishment after the fact unlikely. The Lions' captain, Willie John McBride (Ireland), therefore instigated a policy of "one in, all in" - that is, when one Lions player retaliated, all other Lions were expected to join in the melee or hit the nearest Springbok. By doing so, the referee would be unable to identify any single instigator, and so would be left with the choice of sending off all or none of the team. In this respect, the "99" call was extremely successful - no Lions player was sent off during the tour.

Advantage

"Advantage" is the period of time after an infringement in which the non-offending side have the opportunity to gain sufficient territory or tactical opportunity to negate the need to stop the game due to the infringement. The referee will signal advantage with his arm out horizontally toward the non-infringing team. If no tactical or territorial advantage is gained, the referee will whistle and give the decision that had been delayed. If sufficient advantage is gained, the referee will call "advantage over", and play will continue. The Advantage Law allows the game to flow more freely, and not stop for every minor infringement, giving no incentive for a player to commit "intentional" fouls.

An example of the application of advantage would be if Team A knocked the ball on (technical offence, conceding a scrum) but a Team B player picked the ball up and made a run forwards before being tackled.

Advantage line

Also called the gain line. It is an imaginary line drawn across the centre of the pitch when there is a breakdown in open play, such as a ruck, maul or scrum. Advancing across the gain line represents a gain in territory.
