Do you miss the next game if you get a yellow card?
No. If someone got two yellow cards in two consecutive matches then he will miss next match.
What does "Misses next match if booked" mean in soccer terms?
This means that the player already has one caution (yellow card) from a previous match. In the World Cup, two accumulated cautions in separate matches means that player is ineligible to play in the next match. This player should be careful not to get another caution.
