Rugby union positions

There is a maximum of 15 players from each team allowed to be playing at any time. The players' positions at the start of the game are indicated by the numbers on the backs of their shirts, 1 to 15. The positions are divided into two main categories; forwards (numbered 1 to 8) and backs (numbered 9 to 15). In international matches, there are eight substitutes that can replace an on-field team-mate. The substitutes, numbered 16 to 23, can either take up the position of the player they replace or the on-field players can be shuffled to make room for this player in another position. Typically, the forwards among the substitutes will have lower numbers than the backs. There are no personal squad numbers and a versatile player's position and number may change from one game to the next. Players can also change positions during the match; common examples are the fly-half playing the full-back's position in defence or a prop taking the hooker's position at line-outs. Different positions on the field suit certain skill sets and body types, generally leading to players specialising in a small number of positions. Each position has certain roles to play on the field, although most have been established through convention rather than law. During general play, as long as they are not offside, the players may be positioned anywhere on the field. ==History==

in a traditional football game in Lower Normandy, France, 1867 During early rugby union games there were only really two positions; most players were in the forwards, who formed part of the scrimmage (which later was called "scrummage" and then "scrum"), and a few defensive "tends" (from "goaltenders"). Eventually, the attacking possibilities of playing close behind the scrimmage were recognised. The players who stationed themselves between the forwards and tends became known as "half-tends". Later, it was observed that the players outside scrimmage were not limited to a defensive role, so the tends and half-tends were renamed "backs" and "half-backs". As the game became more sophisticated, the backs positioned at different depths behind the forwards. They were further differentiated into half-backs, three-quarter-backs, and full-back. Specialised roles for the scrum also evolved with "wing-forward" (modern day flankers) being employed to protect the half-back. The first international between England and Scotland was played in 1871 and consisted of 20 players on each side: thirteen forwards, three half-backs, one three-quarter and three full-backs. The player numbers were reduced to fifteen in 1877. Numbers were added to the backs of players' jerseys in the 1920s, initially as a way for coaches and selectors to rate individual players. ==English names of positions==

The various positions have had different names over time, and many are known by different names in different countries. Players in the flanker positions were originally known as "wing forwards", while in the backs, "centre three-quarter" and "wing three-quarter" were used to describe the outside centre and wing respectively (although the terms are still sometimes used in the Northern Hemisphere) The names used by World Rugby tend to reflect Northern Hemisphere usage although fly-half is still often known as "outside-half" or "stand-off" in Britain, and "outhalf" in Ireland. In New Zealand, the scrum-half is still referred to as the "half-back", the fly-half as "first five-eighth", the inside centre as "second five-eighth" and the outside centre simply as "centre". In South Africa the number 8 is known as "eighth man", and in the United States and Canada as "8-man". Collective terms are also used to describe similar positions; the props and hooker form the "front row", the locks the "second row" and the flankers and number 8 the "back row", "loose forwards" or "loosies". The front row and second row combined are termed the "tight five". In the backs, "half-backs" can be used to describe the scrum-half and fly-half; "inside backs" to describe the scrum-half, fly-half and inside centre; "midfield" for the fly-half and both centres (in New Zealand it refers only to the second five-eighth and centre); "outside backs" for the outside centre, wings and full-back: and "back three" the wings and full-back. The two props are distinguished by being either a "tighthead" (their head is positioned between the opposition prop and hooker) or "loosehead" (their head is positioned on the outside of the scrum). The "blindside flanker" binds to the scrum on the side closest to the side line, while the "openside flanker" binds on the side with the most space between the scrum and the sideline. ==Backs==

Full-back , fields the ball from a kick. Full-backs (number 15) usually position themselves several yards behind the back line in defence. They field any deep opposition kicks and are often the last line of defence should an opponent break through the back line. On attack, they can enter the back line, usually near the centres or wings, with the aim of providing an extra person and overlapping the defending players. Three of the most important attributes of a good full-back are good catching ability under a high kick, the ability to punt the ball a long distance with accuracy, and the speed and skill to join in back line attacking moves, especially counter-attacks. The full-back is the player most likely to field the high ball or "up and unders" kicked by the opposition. Good hands are needed to ensure the ball is caught cleanly to deny the opposition the chance to regain possession. As the full-back will inevitably catch the ball deep in their own territory with little support from their own players, they should either kick the ball downfield or run forward to link up with their backs to start a counter-attack. If the full-back kicks the ball out, the opposition have the line-out, whereas if they start a counter-attack they have a number of options. To provide effective cover behind the defensive line, good full-backs are careful not to get caught out of position and must anticipate the opposition's play. Their position behind the backline allows them to see any holes in the defensive line and they either communicate with the backs to close the gaps up or cover the gaps themselves. The full-back has the most potential for attacking the opposition, especially from a misdirected kick. If a kick is fielded and there is enough space and support, the full-back may decide to counter-attack by running the ball back towards the opposition. Due to their kicking skills, in some teams the full-back is also responsible for taking the goal kicks. For much of the history of the sport, the full-back position was almost totally defensive. Originally, the ball could be kicked directly into touch from any spot on the field, with a line-out then following at the spot where the ball went into touch. This effectively placed a premium on full-backs' skills in kicking from hand. The first test tries by full-backs in international matches came relatively early, in 1878 and 1880, but it was not until 1934 that a full-back scored a try in the competition now known as the Six Nations Championship. Only three tries had been scored by full-backs in the Championship prior to 1969. According to rugby historian John Griffiths, the worldwide adoption of the current law restricting direct kicking into touch in September 1968 (a law previously used in Australia) "revolutionised full-back play". J. P. R. Williams of Wales was the first full-back to regularly score tries after the law change, scoring six times in Five Nations matches in the 1970s. Notable full-backs include Serge Blanco, who scored 38 tries in 93 tests for France and was known for his counter-attacking ability. In 1997, he was among the inaugural set of rugby players inducted into the International Rugby Hall of Fame and in 2011 he was also inducted into the IRB Hall of Fame. Four full-backs who played for the British and Irish Lions are in the International Rugby Hall of Fame; Gavin Hastings (also inducted into the IRB Hall in 2013) and Andy Irvine from Scotland, Tom Kiernan from Ireland and the aforementioned Williams. Hastings and Irvine were accurate goal-kickers and Kiernan is credited with being the first attacking full-back in Irish rugby. Williams was chosen as the greatest Lions full-back at the inaugural Lions Legends Dinner at Lord's in 2008 and is praised for his safety under the high ball, tackling and calm decision making. The other full-backs in the International Rugby Hall of Fame are Don Clarke and George Nēpia from New Zealand. Clarke, nicknamed "the boot", was an accurate goal kicker and Nēpia was noted for his tackling and kicking ability. Three-quarters Wing The wings are generally positioned on the outside of the backline with the number 11 on the left and the number 14 on the right. Their primary function is to finish off moves and score tries. Wingers are usually the fastest players in the team and tend to be either elusive runners or, more recently, big, strong and able to break tackles. The skills needed for the left wing and right wing are similar, although left-footed players are usually played on the left wing as they can step and kick better off their left foot. The winger on the blindside often "comes off the wing" to provide an extra man in the midfield, in the same way as would a full-back. One or both wingers will usually drop back on opposition kicks to give the full-back extra options for counter-attacking. There have been a number of notable wings throughout history. David Campese, a member of both the International and IRB Halls of Fame, Welsh international Gerald Davies was influential in helping the British Lions of 1971 become the only Lions touring party to win a test series in New Zealand. Ieuan Evans played 72 games for Wales and scored 33 tries – at that time a record for Wales. In 1994, International Rugby Hall of Famer John Kirwan retired as the (then) most capped player and highest try scorer in All Black history. One of the most notable wingers is Jason Robinson, who played 51 games for England. He also scored 248 points in 159 matches (about 6.5 points per match) for the Sale Sharks from 2000 to 2007. Tony O'Reilly played wing for Ireland between 1955 and 1970 and scored a record 38 tries on two Lions tours. André Boniface is a French international that is a member of both the International Rugby Hall of Fame and the IRB Hall of Fame. Another 2011 inductee in the IRB Hall is Brian Lima of Samoa, In 2012 Demi Sakata, a Japan star, who was considered one of the world's top players of the 1960s, became his country's first inductee into the IRB Hall. Jonah Lomu entered the International Hall in 2007 and the IRB Hall of Fame in 2011, debuted as the youngest ever All Black. Centre passing the ball There are two centres in a rugby team, inside centre (number 12) and outside centre (number 13). The inside centre usually stands close to the fly-half or at first receiver on the other side of the scrum or breakdown. Like the fly-half, they generally possess a good kicking game and are good at reading the play and directing the attack. The outside centre is positioned outside the inside centre and is generally the faster of the two. Outside centres generally have more room to move than inside centres. Centres also provide support at the breakdowns and can run as decoys to confuse the defence. Brian O'Driscoll is the sixth-most-capped player in rugby union history, having played 141 test matches, 133 for Ireland (83 as captain), and 8 for the British and Irish Lions. He is the 8th-highest try scorer in international rugby union history, and the highest-scoring centre of all time. Danie Gerber played centre for South Africa during the apartheid era and even though he was only able to play 24 tests over 12 years, he scored 19 tries. Mike Gibson played for Ireland and the Lions; his record of 69 caps for Ireland lasted for 26 years. Tim Horan won two World Cups for Australia, being named the Player of the Tournament in 1999. As a player, Ian McGeechan won 32 caps for Scotland and went on two Lions tours, while as a coach he led the Lions a record four times. Welsh centre Gwyn Nicholls played from 1896 to 1906 and was known as the "Prince of Threequarters". Other centres in the International Rugby Hall of Fame are Jo Maso and Philippe Sella from France, known for their flamboyant attacking play. Gibson and Sella are also in the IRB Hall of Fame. Guy Boniface, French international and younger brother of André; Zimbabwe international Richard Tsimba; and Bleddyn Williams and Jack Matthews, who formed a legendary centre partnership for Cardiff and Wales in the era immediately following the Second World War. South African Naas Botha scored 312 points (including a record 17 drop goals) despite playing most of his career when the Springboks were boycotted. Australia's Mark Ella used his vision, passing skills and game management to orchestrate a new flat-back attacking style. Grant Fox was one of the most respected goal-kickers who scored more than 1,000 points in all matches for New Zealand. Barry John was known simply as "the king" to Welsh rugby fans and was rated third in the 1971 BBC Sports Personality of the Year Award. Jack Kyle is widely considered Ireland's greatest player. Michael Lynagh took over fly-half from Ella, and in his first test in that position scored an Australian record of 23 points against Canada. Bennie Osler played for South Africa from 1924 until 1933, during which he played a South African record of 17 consecutive games and scored a then world record of 14 points in one game against New Zealand. Hugo Porta is regarded as one of the finest players that Argentina has produced and has been a member of the Laureus World Sports Academy since 2000. Of the players mentioned above, Ella, Kyle, Morgan, Osler and Porta are members of the IRB Hall of Fame. Kennedy Tsimba of Zimbabwe, younger brother of the aforementioned Richard, only played four times for his country, but was one of the world's top fly-halves in the early 21st century, twice being named the player of the year in South Africa's domestic Currie Cup. He was also the first black player to captain the Zimbabwe national team. and went on to captain the Wallabies in nearly half of his 27 tests. Gareth Edwards played for Wales and the British and Irish Lions during the 1970s and is regarded by many as the greatest player in history. Nick Farr-Jones captained Australia through their 1991 Rugby World Cup winning campaign; he was enshrined in the International Hall in 1999. When Joost van der Westhuizen retired in 2003, he had 89 caps, at the time the most for any South African. Of these players, only van der Westhuizen is not in the IRB Hall. which eventually led to their 2012 entry into The Rugby Championship, previously the Tri Nations. Australian George Gregan, inducted in 2013, retired from international rugby in 2007 with a then-world record 139 test caps, and also captained the Wallabies 59 times. ==Forwards==

Back row (Loose forwards) The back row (or loose forwards) consists of three players – two flankers, one on either side of the scrum; and a number eight at the back of the scrum. Number eight The number eight, or eighthman in South Africa, usually binds between the locks at the back of the scrum, providing extra weight at the push. Number eights interact with the scrum-half at the back of the scrum to control and provide clean ball for the backs. They can also pick the ball from the back of the scrum and run with it or pass it to the scrum-half. At line-outs, they can be either another jumper or a lifter. Around the field, they have a similar set of responsibilities as the flankers at the breakdown. Number eights are often strong ball carriers and run off the backs in an attempt to break through or push past the opposition's defensive line. Number eights in the International Rugby Hall of Fame include: Mervyn Davies (Wales and British and Irish Lions), Morne du Plessis (South Africa), Brian Lochore (New Zealand) and Hennie Muller (South Africa). On their own scrum, the loosehead's role is to provide the hooker with a clear view to strike the ball, while the tighthead tries to keep the scrum stable. Props in the International Rugby Hall of Fame include: Jason Leonard (England and Lions), Syd Millar (Ireland and Lions) and Wilson Whineray (New Zealand). Hooker The hooker (number 2) is positioned between the two props in the scrum. After the scrumhalf throws the ball into the scrum, the hooker from the team which threw in the ball must strike for the ball. Any front-row player may use a foot to strike for the ball and gain possession. However, given the role of the props in keeping the scrum stable, it is usually one of the hookers who successfully "hooks" the ball back with the movement of a leg and foot coming into contact with the ball to win possession for their team. Hookers generally have a short back and long arms to aid in binding to the props. Hookers are usually more mobile than the props, and are often used to carry the ball up during open play. Only specialist front-row players can play hooker; if a team cannot field one for any reason, the scrums will become uncontested. was inducted in 2011. Ronnie Dawson of Ireland and the Lions was inducted in 2013. He earned 27 caps for Ireland and appeared 17 times for the Lions from 1958 to 1965, captaining the Lions in six tests; after his playing career ended, he became the first head coach of Ireland and still later served as president of the IRFU and chairman of the IRB Council. ==Utility players==

Players who have the ability to play a number of positions in a team are called utility players. Utility players can be seen as "Jack of all trades" For this reason, many try to avoid being labelled as utilities. Players in the forward positions are generally more specialised than those that play in the backs. However, flankers can usually play number eight, and many players can play lock as well as a back-row position. The front row positions are usually very specialised, although some props can play both sides or even hooker. South Africa captain and IRB Hall of Fame member John Smit has played test matches in every front row position. Another IRB Hall of Fame member to have played multiple forward positions is John Thornett, an Australian utility forward who played at flanker, number 8, lock and prop for the Wallabies from 1955 to 1967. Utility backs tend to cover a greater number of positions, with players commonly switching between scrum-half and fly-half, fly-half and centre, or wing and full-back. Another famous utility player was Austin Healey, who started and played test matches for England and club matches for Leicester Tigers at fly half, scrum-half, full-back and winger. Among members of the International Rugby or IRB Halls of Fame, Mike Gibson has 28 caps at fly-half, 48 at centre and 4 on the wing, and Tim Horan played 62 tests at centre, 2 on the wing and 9 at full-back. Danie Craven mostly played at half-back, but has also started a test in the forwards at number 8. Matt Giteau has also shown great versatility throughout his career, playing 6 tests at scrum-half, 46 at fly-half, 50 at centre and one on the wing. 2013 IRB Hall inductee Waisale Serevi, although most famous as a sevens player and primarily a fly-half in 15s, also started tests as a scrum-half, full-back and wing, and came off the bench once as a centre and once as an emergency lock. An example of a player changing from playing a position in the forwards to one in the backs was Richie Vernon, who began his career as a flanker or number 8 before transitioning successfully into an outside centre. He represented Scotland at Test level in both roles, before retiring in 2019. ==Rugby sevens==

Rugby sevens teams have only seven players on the field and can nominate five substitutes. The seven players are split into three forwards and four backs. Scrums are formed with three players who bind together the same as the front row. There are four backs: scrum-half, fly-half, centre, and wing. The scrum-half feeds the ball into the scrum. The other three players form the backline. Since play is much more open in sevens, with rucks and mauls generally kept to a minimum, most sevens players are backs or loose forwards in fifteen-a-side teams. When a team is defending in open play or from a penalty kick, the defending team will often play a line of six defenders across the field, with one player deeper known as the "sweeper" whose role is to field kicks or to tackle attacking players who have broken through the defensive line. ==See also==
