Cards affect World Cup players mainly through warnings, suspensions, and team disadvantages. A yellow card is a caution, while a red card sends a player off immediately and usually triggers a one-match ban.

How yellow cards work

  • A yellow card warns a player for a foul or misconduct, but the player stays on the field.
  • Two yellow cards in the same match become a red card, so the player is ejected and the team finishes with 10 players.
  • In tournament play, yellow cards can also build up across matches and lead to a suspension.

How red cards work

  • A straight red card removes the player from that match right away.
  • The player also misses the next match, which can hurt the team in a knockout round.
  • FIFA can add extra penalties for serious offenses.

World Cup tournament rules

  • In the 2026 World Cup, yellow cards are wiped clean after the group stage and again after the quarterfinals.
  • That reset helps players avoid missing a later match because of early tournament cautions.
  • Yellow cards from qualifying do not carry into the tournament.

Why it matters

Cards can change a match by forcing a team to play short-handed, and they can change the tournament by suspending important players for later rounds. In some cases, card totals can even affect fair-play tiebreakers in group play.
