Some players choose to forego the scrum caps and just tape their head and ears. A common result of playing rugby is a medical condition called cauliflower ears, which is swelling in the ears caused by blood. Ouch!

In rugby, players can throw the ball backward as many times as they want, just as long as no forward passes are made. This is one of the main rule differences between American football and rugby. If a forward pass happens, the game is stopped, referees give the opposing team a scrum and the throw-in goes to them as well.

1. Yes
   No
2. Yes, but only under certain circumstances.
   Not unless both teams agree at the beginning of each match.

Passes in rugby have to be made to a teammate behind or next to them, but never forward. This is one of the major differences between rugby and American football. The Guinness World Records lists the most consecutive rugby passes as 276 in Newport, U.K. in August 2010.

Originally, teams were allowed to have 20 players on the field, but that was eventually reduced down to 15 by 1876. Each number has a position that has a specific role on the field.

1. Martyn Williams
   Charles Monro
2. Arthur Pell
   William Webb Ellis

William Webb Ellis was a schoolboy playing in a football game when he decided to pick up the ball and run with it to try and score. It was this action that eventually made running with the ball an accepted play.

1. Rugby group
   Rugby league
2. Rugby team
   Rugby unit

Rugby league was created after rugby union, or just rugby, after disagreements of pay to the players. While rugby union allows 15 players on the field to play, rugby league only allows 13.

1. 75 minutes
   90 minutes
2. 80 minutes
   70 minutes

The game is split into two forty-minute periods. Additional time can be added at the referee's discretion based on lost time from injuries or player substitutions. The longest recorded rugby match is said to be over 26 hours long!

1. Rugby World Cup
   Rugby Championship
2. Canada Cup
   Nations Cup

Like the Olympics, the Rugby World Cup happens every four years. The top 20 international rugby teams compete for a chance to win the Webb Ellis Cup, which is named after rugby's creator, William Webb Ellis. The first Rugby World Cup was played in 1985, and the New Zealand All Blacks defeated Australia.

The shape of the ball apparently comes from a pig's bladder. In the beginning, the ball shape actually changed sizes depending on the pig's bladder that was used. Oink oink!

1. Rock, Paper, Scissors

2. Home team
   Coin toss

After the referee tosses the coin, the captain of the winning toss picks whether his team or the opponent will kick off. Captains normally pick based on what their team's strength is.

1. Knock-on
   Hooker
2. Offside
   Charge-down

In rugby there's no getting away with not being allowed to move the ball forward, even if it's by accident. When a knock-on (sometimes called knock-forward) happens, the referee gives a scrum to the team that didn't commit the knock-on.

1. Ruck
   Scrum
2. Obstruction
   Touchlines

If a player or the ball crosses the line, the play is stopped, usually by the touch judge. The teams both then form a line out and the ball is thrown back into play.

1. Loosehead prop
   Right wing
2. Hooker
   Scrum half

The scrum half is the facilitator of where the ball is going next. In this position, the player needs to be able to call plays, react quickly and read plays among several other skills. Joost van der Westhuizen is known as the best scrum half of all time.

1. 2 halves
   4 quarters
2. 1 period
   3 quarters

There are two forty-minute periods in rugby, and in between the two periods there's a ten minute break. A rugby game typically last an hour and a half.

1. Offside
   Onside
2. Outside
   Inside

There surprisingly isn't a penalty or offense for being offside, but a player can't be part of the game until they are back onside. In American football, there's a five-yard penalty for a player that jumps offside.

1. A lineout
   A scrum
2. A penalty
   A drop goal

Both teams line up on the sideline, and a player throws the ball straight down the middle of the line. Players can lift their teammates in the air to try and catch or tap the ball to a teammate, which will then put the game back in play. In early rugby days, it was actually illegal to lift players during a line-out.

1. The cross bar
   Scrum
2. Goal line
   The cross mark

The crossbar is three meters from the ground, while the goal posts are 5.5 meters apart from each other. In American football, there's no crossbar, just two goal posts that the ball has to pass through. Eamonn and Jackson Hickson hold the Guinness World Record for the most conversions recorded in a game at 30!

1. Yellow
   Red
2. Blue
   Green

Once a player has committed the foul, they immediately sit out the game for ten minutes. Two yellow cards in a match result in a red card, resulting in the dismissal of the remainder of the match. In 1995, South Africa got three red cards in one game, the most by any team in a single match. That must've been an intense game!

1. Scrum-half
   Backs
2. Flanker
   Forwards

Forwards are typically bigger and stronger than backs and do a majority of the tackling. They also form the scrum and lineout and are responsible for helping the backs advance the ball.

1. Goal zone
   Crossbar
2. Goal line
   Offside

The ball has to touch the player when it makes contact with the ground for the try to be counted and the team earns five points. Daisuke Ohata is the rugby's all-time leading try scorer with 69. Now that's impressive!

1. Goal zone
   Sin-bin
2. The box
   Outsider

Players are sent to this area for ten minutes for committing the penalty. Sin-bin wasn't added to rugby until 2001. Barry Jensen was the first player ever sent to the sin-bin.

Jonny Wilkinson has the most drop goals recorded by a rugby union player with 36. Wilkinson recorded these drop kicks from 1998-2011. While the kicker drops the ball and tries to kick it through the goal, the opposing team attempts to stop the kick. The tricky part is that the ball has to bounce before it can be kicked.

1. A hook
   A scrum
2. A ruck
   A maul

A ruck happens after a player is tackled and falls on the ground. When this happens, the tackler has to let go of the tackled player, and the tackled player must release the ball.

1. Only the player in possession of the ball
   Anyone on the field
2. Only backs
   Only forwards

Players are allowed to tackle their opponents using their head, arms and body. A player can be tackled anywhere except for their neck and head. In American football, Tackles can be made while a player is in the air, but it's not allowed in rugby.

The fullback is the last line of defense and responsible for making key attacks and tackles. Fullbacks need to be strong catchers because they do get deep kicks from the opposition.

While there may only be one referee, there are two touch judges who help the referee in certain situations. Before 1875, captains were responsible for making the decisions, and there weren't any referees.

1. Wing
   Backs
2. Forwards
   Scrum

The backs are responsible for advancing the ball up the field and scoring tries. In comparison to forwards, backs are usually smaller and faster and score most of the points. Israel Folau is ranked as one of the greatest backs of all time.

When William Webb Ellis decided to run with the ball, he was playing at school in Rugby, England. The sport was named after Ellis' school in honor of him essentially creating it.

1. Turf
   Field
2. Pitch
   Track

The pitch is close to the same size as a soccer field. Rugby end zones are 25 yards deep, whereas in American football it's 30 yards.

1. 10 minutes
   15 minutes
2. 20 minutes
   12 minutes

When teams return from halftime, they switch ends and attempt to score on the end they were previously defending. The origin of halftime actually came from the same place the sport got its name from, the Rugby School. A school captain felt his team had an unfair advantage because of windy conditions so he suggested switching ends and the rest is history.

In most sports, substitutions are made to replace an injured player, a strategic approach or for some fresh legs on the field. But in rugby, once a player is substituted, they can't go back on the pitch except for blood injury and replacing an injured front-row player. Much different from American football!

The four main ways to score are a try, goal kick, penalty and drop kick. A try is worth the most points out of the four options. The highest-scoring Rugby World Cup game was in 1995 when the All Blacks beat Japan 145-17.

1. Scrum
   Advantage
2. Knock-on
   Penalty kick

The referee's arms will then be horizontal pointing toward the team to throw the ball in. The referee will then blow the whistle to signal the scrum to begin. The scrum wasn't introduced to rugby until 1905, and since then, rules have varied and changed.

While rugby's style of play had been around for many years before, it wasn't until William Webb Ellis' move forward that it solidified its name. As you've no doubt gleaned by now, Ellis was playing at the Rugby School when he essentially invented the sport.

1. 110 yards
   120 yards
2. 100 yards
   125 yards

A rugby pitch is just 10 yards shorter than American football's 120-yard field. In rugby, they measure by meters.
