Unit 35, Soccer Rules. Soccer is one of the most popular sports in the world. Although the main idea of the game is easy to understand, there are many rules to be followed.

He is ejected from the game. Another rule is about handling. Handling is when another player touches a ball with his hands on purpose. Players cannot handle the ball. A player may not do anything that is dangerous to another player. He cannot kick an opponent's leg to get the ball. There are also some lesser known rules.
