If a soccer player receives two yellow cards in a match, they receive a red card and are ejected from the game. This means that they must leave the field of play, and their team must continue with one less player. A yellow card acts as a warning, and accumulating two leads to disciplinary action, demonstrating the need for players to maintain sportsmanship and adhere to game rules. This system aims to ensure fair play and minimize foul behavior during the match.
