What is indicated by a player receiving a second yellow card in a match?

When a player receives a second yellow card during a match, it leads to the issuance of a red card. This red card indicates that the player is being shown the consequences of receiving two cautions, which results in their ejection from the game. Consequently, the player must leave the field and cannot continue participating in the match. This rule is designed to maintain discipline on the field and discourage misconduct by penalizing players who repeatedly commit fouls.

In contrast, receiving either a single yellow card or having a team receive a free kick for an infringement does not lead to ejection. The yellow card serves as a warning, while a red card signifies that the player must exit the match entirely.
