Can a player be cautioned for dissent if they yell at their coach?

A player cannot be cautioned for dissent simply for yelling at their coach. The Laws of the Game specify that dissent pertains to a player's behavior towards match officials, such as the referee or assistant referees. Dissent occurs when a player shows disagreement or disrespectful behavior towards decisions made by match officials.

Yelling at a coach does not fall under the category of dissent related to match officiating. While it may not be considered sportsmanlike conduct, it does not meet the criteria necessary for a caution under the rules governing the game. Dissent must specifically target officials, and communication between a player and coach does not involve the same level of accountability under the Laws. Thus, the proper interpretation is that this situation does not warrant a caution.
