At the Club World Cup taking place in a month, decisions made by the Video Assistant Referee will be explained to spectators in the stands as well as to television viewers.
If the Moroccan trial is a success, other Fifa competitions may adopt it, according to the International Football Association Board (Ifab).
The Women's World Cup this summer might be a part of that.
In the meantime, the Premier League's planned trial of a temporary concussion replacement has been scrapped.
Following a request from the World Leagues Forum and Fifpro to test the protocol in the English top flight, Ligue 1 in France, and Major League Soccer in the United States, it was discussed at the Ifab meeting on Wednesday at Wembley.
Since they were approved in 2020, the current concussion protocols, which permit additional permanent substitutions, have come under fire. Campaigners have cited instances in which players were permitted to remain on the field only to be later replaced.
Despite having backed the idea of a trial, Football Association (FA) Chief Executive Mark Bullingham claims that no agreement could be reached and that the current permanent concussion substitute trial will go on indefinitely.
Because there are players who, in our opinion, appear to have suffered a concussion but have not been removed from the game, we believe it would be worthwhile to test out [temporary concussion substitutes]." said Bullingham.
The justification for an evaluation away from the field of play is that you can learn more in 15 minutes than you can in three.
"However, the decision was made to strengthen the use of the permanent model through more education, more support, and more motivation, so that the concept of making the right decisions becomes a reality.
"Permanent substitutes are the most secure option if done properly because the player would be removed at the first sign of suspicion. ".
Dr. Adam White, Head of Brain Health for the Professional Footballers' Association (PFA), described the denial of a temporary concussion replacement trial as "extremely disappointing.".
If football's lawmakers, in the opinion of player unions and leagues, are preventing them from doing what is necessary to ensure players' safety, there is a fundamental problem, according to White.
The next step will be for unions and leagues to talk about what this means and their options. ".
In a joint statement, the association of professional football leagues, World Leagues Forum, and the global players' union Fifpro said they were "greatly disappointed" by the choice and would "further assess the situation" and "consider [their] options moving forward.".
Referees must inform players of VAR rulings.
The lack of communication between VAR decisions and fans has become increasingly frustrating.
If successful, a 12-month trial regarding stadium communication at Fifa events will continue at the women's World Cup in Australia and New Zealand and then the men's Under-20 World Cup in Indonesia. The trial will start at the Club World Cup, which runs from 1-11 February.
The preferred language of communication in Morocco will either be French, English, or Arabic.
A system that followed the cricket and National Football League (NFL) models of straightforward explanations would make the decisions more understandable to spectators watching at home and inside stadiums.
Bullingham continued, "We don't believe fans are receiving enough information.
"We are testing this in the most difficult environment first because we believe domestic leagues will make it simpler. ".
Prepare for additional injury time.
Ifab also praised its "successful" stoppage time policy at the World Cup in Qatar, where games lasting more than 100 minutes, including stoppages, became the norm.
It wants to increase the amount of time the ball is in play and, having ruled out alternatives like a countdown clock, thinks changes can be made to the game's current setup.
To put it simply, this entails timing injury delays and adding that precise amount at the conclusion of a game rather than a broad estimate of the total time, which will be communicated as guidance to all domestic competitions starting in the 2019–20 season.
Bullingham believes that once the players are aware of the implications, the potential for significant amounts of injury time will diminish.
He asserted that there would be less injury time once there was no incentive to remain injured.
debate from the sidelines.
The issue of players interfering with play was included in the initial offside decision guidelines that were first communicated last summer.
It was discussed whether there was a legal gap that needed to be closed in light of the controversy surrounding Manchester United's controversial equalizing goal against Manchester City on Saturday.
Bullingham stated, "We came to the conclusion that there is no legal gap.
