A historic moment at the World Cup

The 2026 FIFA World Cup witnessed a historic first on Friday during the Türkiye vs Paraguay clash in Group D.

Miguel Almirón became the first player to be sent off under one of the new regulations introduced by FIFA and IFAB ahead of the tournament.

The incident occurred following a heated exchange between several players on the field. During the confrontation, Almirón was seen speaking to Turkish defender Mert Müldür while partially covering his mouth with his hand.

VAR stepped in and the decision followed

The incident was reviewed by the video assistant referee, prompting immediate attention from the officiating crew.

After receiving the recommendation from the VAR room, Salvadoran referee Iván Barton reviewed the play and ultimately showed a red card to the Paraguayan midfielder.

The decision sparked protests from Paraguay's players, but replays appeared to show a clear violation of one of the tournament's newly implemented regulations.

The sending-off left Paraguay a man down during a crucial stage of the match and quickly became one of the most talked-about moments of the day.

What is the so-called "Vinicius Rule"?

The regulation was introduced in the months leading up to the World Cup following debates surrounding situations in which players attempted to conceal comments directed at opponents.

Under the new rule, players are prohibited from covering their mouths with their hands, arms, or jerseys while engaging in confrontational exchanges with opposing players.

The measure was developed after a controversial incident in the UEFA Champions League and was later reviewed by football's rule-making bodies before being included as part of a broader package of World Cup regulations.

A warning for the rest of the tournament

Almirón's dismissal now stands as the first recorded case under the new rule at a FIFA World Cup and could serve as an important warning for players throughout the competition.

FIFA has repeatedly emphasized that the new regulations are designed to increase transparency on the field and help officials better manage potentially controversial situations.

As a result, the incident at Levi's Stadium may be remembered as one of the defining moments of the group stage—not only because of the red card itself, but because it marked the first enforcement of a rule that is already generating significant debate across the football world.
