FIFA has blocked rock concerts from being staged in World Cup stadiums in the weeks before the 2018 tournament kicks off in Russia.
FIFA passed a rule "to ensure that the field of play is of the highest quality, it shall not be used for a non-football event" for two months before a stadium's first match.
In updated 2018 World Cup regulations published Monday, FIFA requires "explicit prior approval" for exemptions.
FIFA has also introduced disciplinary records — a points system adding up red and yellow cards — as a potential tiebreaker in the group stage when teams have the same amount of points in the group stage.
