In the World Cup, referees are not hesitant to show yellow and red cards to players who break the rules. The tournament's disciplinary rules are designed to ensure fair play and sportsmanship.
Yellow cards are reset at two stages of the tournament: after the group stage and again after the quarter-final stage. This means that players who receive a yellow card in the group stage will not be suspended if they receive another yellow card in the Round of 32.
However, players who receive a yellow card in both the Round of 32 and Round of 16 will be suspended for their team's quarter-final game. Similarly, players who receive a yellow card in either the Round of 32 or Round of 16 and then another yellow card in the quarter-final will miss their team's semi-final game.
A yellow card received in the semi-final will not prevent a player from participating in the final. The only way a player can be ruled out of the final is by receiving a red card in the semi-final.
Players who receive a red card in the World Cup will be suspended for their team's next game, regardless of the stage of the competition. There is no exception to this rule.
Neither yellow cards nor red cards resulting from a second yellow card can be appealed. However, players who receive a straight red card can appeal to FIFA within a limited timeframe after the match.
If an appeal is successful, the card can be overturned. However, the committee hearing the appeal also has the power to extend the ban in cases where violent conduct is involved.
