In any football tournament, such as the World Cup, fouls are committed by players during matches, after which a yellow or red card is shown by the referee._x000D_
_x000D_
Every time the referee puts his hand in his pocket, it is not known which color card will come out._x000D_
_x000D_
But the question is, what are yellow and red cards?_x000D_
_x000D_
These cards are issued by the referee for dangerous or undesirable behavior._x000D_
_x000D_
Also called penalty cards, a yellow card is basically a warning, while a red card leads to immediate expulsion from the match._x000D_
_x000D_
When did the practice of showing cards start?_x000D_
_x000D_
You will be surprised to know that the use of yellow or red cards in football has not been very long._x000D_
_x000D_
The introduction of these cards to football was due to several incidents and controversies and was first suggested by a FIFA official and referee, Sir Kenneth George Austin._x000D_
_x000D_
In fact, two incidents led Sir Kenneth George to think about the penalty card system._x000D_
_x000D_
_x000D_
_x000D_
The most important of these was the match between Chile and Italy in Santiago in the 1962 World Cup, in which the first foul was committed within 12 seconds of the start and a player was sent off 8 minutes later._x000D_
_x000D_
The police had to be called four times during the match because the players were fighting each other._x000D_
_x000D_
The second incident was the conflict between England and Argentina during the 1966 World Cup._x000D_
_x000D_
Before these cards were used, players were given a verbal warning and it was very difficult for all parties to track it._x000D_
_x000D_
Why were these colors of the cards chosen?_x000D_
_x000D_
Sir Kenneth George got the idea of ​​choosing these colors for the cards by looking at traffic signal lights._x000D_
_x000D_
He was driving past Wembley Stadium when he came up with the idea for a system of colour-coded cards._x000D_
_x000D_
Yellow means a warning or a clear signal to a player to consider his actions._x000D_
_x000D_
Red means a complete stoppage, meaning the player is not allowed to continue playing._x000D_
_x000D_
Both colours of cards were first used at the 1970 FIFA World Cup and have now been in use for over 50 years._x000D_
_x000D_
What does a yellow card mean?_x000D_
_x000D_
A yellow card is issued for minor offences and is the most commonly used card in football._x000D_
_x000D_
When a player is shown a yellow card, he does not face any immediate consequences._x000D_
_x000D_
The player who receives a yellow card is allowed to continue playing and the referee writes the reason, the player’s name and number on the card._x000D_
_x000D_
This helps the referees track which players were shown cards in a match and needs to be monitored for future matches._x000D_
_x000D_
If a player is shown a yellow card twice in a match, it becomes a red card and he has to leave the match._x000D_
_x000D_
No substitute for that player can take his place in the team and the team has to complete the match without a player._x000D_
_x000D_
This does not have to happen in the same match, if a player is shown a yellow card in 2 different matches, he will not be allowed to play the next match._x000D_
_x000D_
If a player is given a yellow card in the group stage of a tournament, he must avoid another card until the quarter-finals, otherwise he will not be allowed to play the next match._x000D_
_x000D_
If a yellow card is shown in the semi-finals after the quarter-finals, it will be considered the first._x000D_
_x000D_
What is a red card?_x000D_
_x000D_
A red card is issued for a serious or violent incident and results in the player being sent off immediately and cannot be replaced._x000D_
_x000D_
A red card is the referee’s last resort and is therefore not as common as a yellow card, however, when a player is shown this card, they are sent off and suspended for the next match._x000D_
_x000D_
This punishment can be more severe, but it depends on the reason for the red card._x000D_
_x000D_
So far, 8 red cards have been issued in the ongoing World Cup in the United States, Canada and Mexico._x000D_
_x000D_
Interestingly, if a goalkeeper is shown a red card during a match, the team will play with 10 players, although a substitute goalkeeper can be part of the game if the team has not met the quota of substitutes._x000D_
_x000D_
If the quota has been met, then the goalkeeper has to be replaced by one of the team’s 10 players._x000D_
_x000D_
A goalkeeper usually receives a red card when he goes outside the penalty area and prevents a player from the opposing team from scoring a goal.
