A yellow card in soccer means a warning from the referee for a cautionable offense, like a reckless tackle, dissent, time-wasting, or unsporting behavior. A player can usually stay in the game after one yellow, but two yellow cards in the same match become a red card and the player is sent off.

What it does

  • Warns the player to stop the behavior.
  • Goes on the referee’s record as a booking.
  • Can affect later matches if yellows are accumulated across a tournament or league.

Simple example

If a player slides in late and makes a reckless challenge, the referee may show a yellow card. If that player later argues too aggressively with the referee and gets another yellow in the same match, they are sent off with a red card.

In one line

Yellow = “careful, that’s your warning.” Red = “you’re out.”
