Decisions made by the Video Assistant Referee are set to be explained to television viewers and those in the stadium at next month’s Club World Cup.
International Football Association Board (Ifab) says if the trial in Morocco is a success then it could be rolled out at other Fifa competitions.
That could include this summer’s Women’s World Cup.
Meanwhile, a temporary concussion substitute trial in the Premier League next season has been ruled out.
It was discussed when Ifab met at Wembley on Wednesday following a request from world players’ union Fifpro and the World Leagues Forum to test the protocol in the English top flight, Ligue 1 in France and Major League Soccer in the United States.
The current concussion protocols, which allow an additional permanent substitution to be made, have come in for criticism since they were approved in 2020, with campaigners highlighting instances where a player has been allowed to stay on the pitch before later being substituted.
