In the event of an actual or suspected concussion, Qatar 2022 protocol allows for a single additional permanent concussion substitution (APCS).
This substitution allows a team to withdraw a player who may have suffered a brain injury but does not impact the five permitted substitutions. The opposing team is granted an additional substitution with each APCS to avoid any advantage.
It will be the first time such a rule is implemented at a FIFA World Cup.
Medical staff, known as “concussion spotters”, will also review video technology for possible concussions.
Two additional permanent concussion substitutions (APCS) have been allowed in the Premier League since February 2021, when they were introduced as a trial.
The Premier League, Football Association and English Football League have since adopted the rule permanently.
