Can players be suspended for World Cup semifinals?
Rules for yellow cards have changed slightly for the 2022 World Cup with FIFA keen to avoid a player missing a final because of a suspension.
However, players can miss a semifinal, if they receive a second yellow card of the tournament at the quarterfinal stage, as per FIFA regulations for the 2022 tournament.
Argentina’s Marcos Acuna and Gonzalo Montiel both picked up their second yellows against the Netherlands and will miss a semifinal match vs Croatia as a result.
Players can also be suspended for a semifinal match, if they receive a red card in a quarterfinal game. This happened to Morocco’s Walid Cheddira who was sent off after picking up two quick yellow cards against Portugal and has been suspended for their semifinal against France.
