These are the regulations of the field. Also in the above picture when a ref calls a foul he will blow his whistle and will signal which direction the kick will be taken. In the picture at the right a ref is showing a substitute. |

In soccer when you commit a dangerous foul you can be awarded a card. If is is dangerous but non-harmful you could receive a yellow card. If you try to hurt someone or recklessly go after someone you could receive a red card. A yellow card is a warning. A red card means you are ejected from this game and the next. Also two yellows equals a red. |
