Concussion substitutes: System in place at Club World Cup in Qatar
Al Jazeera, 06 Feb 2021
For the first time at a FIFA tournament, concussion substitutes are being trialled in Qatar at the Club World Cup.
This means even if a team has used all its allowed replacements, an additional substitute can be brought on
if a player is struggling with a head injury.
A similar system is already used in rugby where the use of temporary replacements gives medical staff longer to assess a player before deciding if they are fit to continue.
FIFA says the system being used at this tournament is on trial only and more research is needed before any permanent changes to the laws are approved.
