Most forms of football have a move known as a tackle. The primary and important purposes of tackling are to dispossess an opponent of the ball, to stop the player from gaining ground towards goal or to stop them from carrying out what they intend.
The word is used in some contact variations of football to describe the act of physically holding or wrestling a player to the ground. In others, it simply describes one or more methods of contesting for possession of the ball. It can therefore be used as both a defensive or attacking move.
In Middle Dutch, the verb tacken meant to grab or to handle. By the 14th century, this had come to be used for the equipment used for fishing, referring to the rod and reel, etc., and also for that used in sailing, referring to rigging, equipment, or gear used on ships. By the 18th century, a similar use was applied to harnesses or equipment used with horses. Modern use in football comes from the earlier sport of rugby, where the word was used in the 19th century.
In American football and Canadian football, to tackle is to physically interfere with the forward progress of a player in possession of the ball, such that his forward progress ceases and is not resumed, or such that he is caused to touch some part of his body to the ground other than his feet or hands, or such that he is forced to go out of bounds. In any such case, the ball becomes dead, the down is over, and play ceases until the beginning of the next play.
A tackle is known as a quarterback sack when the quarterback is tackled at or behind the line of scrimmage while attempting to throw a pass. A tackle for loss is a tackle that causes a loss of yardage for the opposing running back or wide receiver. This happens when the quarterback is sacked, when either a rusher or a receiver is tackled behind the line of scrimmage, or when the ball is fumbled behind the line of scrimmage and was picked up by an offensive player who does not manage to move past the line before being tackled. When a player who does not have the ball is taken down, it is generally referred to as a block.
Tacklers are not required to wrap their arms around the ball carrier before bringing him to the ground; in fact, the ball carrier is often "tackled" by the defender taking a running start and hitting the ball carrier to knock them to the ground. Tackles can also be made by grabbing the ball carrier's jersey (or even hair, should it be long enough and allowed to dangle freely from beneath the helmet) and pulling him to the ground. As mentioned above, the referee can declare that a play is dead if the ball carrier's forward progress has been stopped, even if he has not actually been taken to the ground.
To protect players from potentially catastrophic injury, there are some restrictions on tackles and blocks. At no time may a defensive player tackle an offensive player by grabbing the facemask of their helmet; doing so incurs a 15-yard penalty and the victimized team is awarded a new set of downs. Although spear tackles are allowed in gridiron football, a player may not use his helmet to tackle an opponent as the technique can cause serious injury to both players (more often the tackler, due to the force of reaction on the tackler, which is apt to be beyond the limit that the neck can handle) and also warrants a 15-yard penalty as well as a fresh set of downs if committed by the defending team; this is known as "spearing the player". A similar penalty is assessed to any player attempting to make contact with his helmet against another opponent's helmet, which is known as a helmet-to-helmet collision. Grabbing a ball carrier by the pads behind his neck and pulling him down is known as a "horse collar", a method which has been made illegal at all levels of American football.
It is also illegal to tackle a player who has thrown a forward pass (generally a quarterback) after he has released the ball; doing so is called "roughing the passer" and incurs a 15-yard penalty and a fresh set of downs for the team with the ball. However, in the NFL a player can continue forward for one step, which means that often a player who is committed to attacking the quarterback will still make a tackle. Place kickers and punters are afforded an even greater protection from being tackled.
Once the play is ruled complete, no contact is permitted; a player who makes contact with an opponent after the play is charged with "unnecessary roughness" and his team is assessed a 15-yard penalty.
Blocks that occur in the back of the legs and below the knees, initiated below the waist, or clotheslines are also generally prohibited and players who use them are subject to much more severe penalties than other illegal tackles. However, a player who plays on the line can block below the knees (cut block) as long the block is within five yards of the line and the player they block is in front of them and not engaged by another blocker (chop block).
In the National Football League (NFL), tackles are tracked as an unofficial statistic by a scorekeeper hired by the home team. Though the statistic is widely cited, the league does not verify that the counts are accurate.
Unlike other codes, tackles in association football have to be predominantly directed against the ball rather than the player in possession of it. This is achieved by using either leg to wrest possession from the opponent, or sliding in on the grass to knock the ball away. A defender is permitted to use their body to obstruct the motion of a player with the ball, and this may be part of a successful tackle. Pulling a player to the ground in the style of tackle common to other codes is completely absent from the game (this would be considered "serious foul play" and result in a dismissal).
Although some contact between players is allowed, the rules of association football significantly limit the physicality of tackles, explicitly forbidding contacts which are "careless, reckless or [use] excessive force". Almost all tackles where the tackler's legs make contact with the opponent before the ball are considered illegal, and heavy contact after initially touching the ball may also be penalised.
Illegal tackles are fouls and are punished with a direct free kick (or penalty if committed within the penalty area) for the opponent's team. Such incidents are common, with dozens of occurrences in a typical match. In most cases these fouls are not considered misconducts, however yellow cards (cautions) may be delivered for more egregious fouls that constitute "unsporting behaviour". If a foul tackle endangers the tackled player's safety, it is likely to be considered as "violent conduct" by the referee and punished with a red card (dismissal).
Tackles that involve lunging at an opponent with both legs, regardless of whether the ball is won, are generally considered to constitute serious foul play and hence result in a sending-off. This explicitly includes "scissoring" (tackling with legs apart, so as to trap the opponent's leg or legs in between), which is likely to be punished with a send-off (red card), as it poses a high risk of severe knee injury to the player being tackled. Tackling with studs up is considered dangerous. A studs up tackle is made when a player lunges into a tackle with a leg or both legs outstretched exposing the soles of their boots. Referees are encouraged to at the very least caution (yellow card) players who commit such challenges.
The most spectacular form of tackle in association football is the slide tackle, wherein a tackler slides, leg extended, along the ground, aiming to hit the ball away. This form of tackle carries a high risk of committing a foul.
"Diving" in association football involves tackled players exaggerating the physicality of tackles, so as to gain favourable decisions from the referee.
In Australian rules football, the move commonly described as a "tackle" is similar to in rugby and involves wrapping, holding or wrestling a player who has possession of the ball to the ground. Players not in possession of the ball are not allowed to be tackled, and will receive a holding the man free kick if tackled.
As there is no offside rule in Australian rules football, players can be tackled from any direction, and are often blindsided. For this reason, the sport allows players to shepherd and bump their opponents within 5 metres of the ball, to protect the ball carrier.
A tackled player must immediately dispose of the ball legally, by kicking or handballing, but not by throwing or dropping the ball. If this is not done, a holding the ball free kick will be awarded to the tackler. If the ball is knocked free by the tackler, pinned to the player by the tackler, or the player unsuccessfully attempts a kick or handball, a free kick will only be awarded if the ball carrier is deemed to have had a prior opportunity to dispose of the ball prior to being tackled. If a player has not had prior opportunity to dispose of the ball and a tackler knocks the ball free during a tackle then no free kick is paid and the game continues.
A tackle must only contact below the shoulders and above the knees, and a player is able to be thrown to the ground, so long as the tackle is deemed not to be reckless or likely to cause injury. There are also rules outlawing pushing in the back making tackling more difficult. Tripping, by both hand or foot, is not allowed and can be a reportable offence.
Players wear little to no padding to cushion the impact of tackles, however players generally wear mouthguards to protect their teeth.
There are many types of tackles in Australian rules football:
Although the term "tackle" is used in Australian rules to exclusively describe wrapping, holding or wrestling a player in possession, there are also several other ways of contesting possession in Australian rules that other sports would describe as a "tackle" and that also involve a degree of contact.
Other defensive actions are generally categorised as one percenters. The defensive tactic of punching away (commonly known as spoiling) from a player is allowed. Smothering, which involves using the arms or body to get in the way of an opponent's kick as it leaves their boot, is similar to a charge down in rugby football.
Gaelic football defines tackling as wresting the ball from an opponent's hands. Bumping is allowed on the player with the ball, but a player cannot be grabbed.
International rules football is a hybrid game between Australian rules football and Gaelic football. Tackling in International Rules is subject to similar rules as Australian rules football, but with some subtle differences. Tackling is only allowed as low as the waist, whereas it is allowed down to the knees in Aussie Rules. One handed tackling has been banned in International Rules since the 2008 International Rules Series.
In rugby league the ball-carrier can be tackled by any number of defenders from any direction. The initial contact in the tackle must be made below the ball carrier's neck or it will be deemed a high tackle and penalised. A tackle in rugby league is completed when any of the following occurs:
Once the tackle is completed, the ball-carrier must be allowed to get to his feet to 'play-the-ball' and the defensive team must retreat 10 metres (except 2 markers, facing the tackled player). Spear tackles are illegal in rugby league, with most tackles in which the defender is lifted 'above the horizontal' bringing about penalties in the modern game. A stiff arm tackle is an offence. A 2012 New Zealand study found that over 659 tackles are made per game in professional rugby league. Of all the rugby league positions, second-row averages the most tackles.
In rugby union, a player must be brought to ground for a tackle to be completed. The tackled player must release the ball, but the ball is not dead and a ruck forms to contest possession of it. If the ball carrier is not brought to the ground a maul will usually form. High/reckless or stiff arm tackles laws once dictated any contact made above the shoulders was an offence. Now, even if contact starts below the shoulders, if the head is involved in any reckless tackle it results in the offending player being given a yellow card and therefore sin binned. World Rugby now defines a reckless tackle as being any contact where the tackler "knew or should have known that there was a risk of making contact with the head of an opponent, but did so anyway"
For various codes of football, variant codes have been developed which substitute out the tackling element, making the game less physical. In these games, either a being touched by an opponent or, in some codes, having a tag on the player's person removed, has effects similar to a tackle in the parent code.

Some illegal tackle moves result in a penalty play, however others may be "reportable" offences -- that is, the option exists for an official to penalise a player's conduct individually rather than during the game refer it to a tribunal for deferred penalty.
