When can a player be cautioned with a yellow card without contact?

A player can be cautioned with a yellow card without any physical contact when they engage in behaviors that violate the laws of the game in a manner that does not involve direct play or interference with other players. This includes actions such as dissent, which encompasses any verbal or non-verbal disagreement with the referee's decisions, delaying the restart of play—such as taking too long to set up for a free kick or corner—or entering or exiting the field without permission from the referee.

These actions are considered unsporting behavior and warrant a caution as they can disrupt the flow of the game and undermine the authority of the referee. Therefore, they are taken seriously, even when no physical contact occurs on the field. This reinforces the idea that maintaining respect for the game and its officials is essential for sportsmanship and fair play.

Other scenarios mentioned, like aggressive celebrations or arguing without direct reference to dissent, typically involve different violations or are not specifically categorized as cardable offenses without contact. Similarly, excessive time-wasting during a throw-in is often considered delaying the restart of play and may also lead to a yellow card, but it is a specific instance that can be classified under the behaviors highlighted in the correct answer.
