Players at the 2018 World Cup will be banned for one match if they pick up two yellow cards before the quarter-final stage.
The list of players who have already picked up a yellow card going into the round of 16 is long, but some of the most prominent players in the world also fall into that category.
The likes of Lionel Messi, Cristiano Ronaldo, Neymar and Kevin de Bruyne also happen to fall into that category.
These players are very instrumental to their teams, so they need to be careful not to pick up any other yellow cards.
Messi was booked for time wasting against Nigeria and Ronaldo got one for throwing his arm against a marker.
