A similar rule is written into tournament rules for this year's World Cup.
FIFA would typically open disciplinary cases if teams breached the rule, but its scope for punishment is likely limited to imposing fines of about 10,000 Swiss francs ($10,500) on some of its wealthiest member federations.
The "One Love" campaign promotes diversity and inclusion in soccer and was started in the Netherlands. Last year, Georginio Wijnaldum wore the armband at a European Championship game in Hungary with the consent of UEFA, the governing body of European soccer.
In September, 10 European teams said their captains would wear the armband in upcoming UEFA-organized games. Eight of those had qualified to play in Qatar and said they would also ask FIFA for permission. France has since withdrawn support citing a wish to show respect for Qatar.ADVERTISEMENT
FIFA had not publicly responded to the requests before president Gianni Infantino announced an in-house alternative in Doha.
The FIFA choice of slogans for group games include "SaveThePlanet," "ProtectChildren" and "ShareTheMeal." The slogan "NoDiscrimination" - the only one aligned with the European teams' wish - will appear at the quarterfinal stage.
