The new rule follows controversy during a Champions League game in February when Benfica winger Gianluca Prestianni was accused of racially abusing Real Madrid star Vinicius Junior.
Prestianni was accused of calling Vinicius a "monkey" repeatedly while covering his mouth. Prestianni denied racially abusing Vinicius but was later banned for six matches – with three of those suspended – for “homophobic conduct”.
FIFA also confirmed said that red cards would also be introduced for players leaving the field of play in protest at a referee’s decision, while a team causing a game to be abandoned will forfeit the match.
FIFA has also approved a change to the way sanctions are enforced during the World Cup.
From this year’s tournament, single yellow cards issued to players in the group stage will be cancelled after the first round, and then again after the quarter-finals.
The move is aimed at ensuring that star players do not find themselves suspended for crucial games in the tournament after collecting two separate yellow cards.
The 2026 World Cup kicks off in Mexico City on June 11.
