Rodrigo Aguirre became the first player expelled in Liga MX under the Ley Prestianni on Thursday, after he was shown a red card in the first half of the Tigres-Tijuana match for covering his mouth while speaking to an opponent. The decision turned a routine dispute into a precedent, because the dismissal was not for the argument itself but for the way Aguirre chose to speak during it.
That is why his name is being searched now. The red card came in the Apertura 2026 and immediately raised the question of where the line now sits in Liga MX: under the new FIFA-backed rule, a player can be sent off with a straight red card if he deliberately covers his mouth while talking to a referee or an opponent during a match. Aguirre was the first to pay for it in the league.
The play unfolded near the end of the first half, after a dispute involving Alejandro Gómez and Fernando Gorriarán. Gorriarán stepped in to separate the players, and Gómez could be heard saying, “¡Ya, ya!” in an effort to cool things down. Aguirre was still caught in the middle of the confrontation, but he was the one punished by Ismael Rosario López Peñuelas, who applied the red card after the mouth-covering exchange.
That detail matters because it shows how quickly the rule can shift responsibility from the general melee to one specific gesture. Aguirre was arguing in a scene already crowded with voices and bodies, yet the sanction landed on him alone. The rule does not require a racial slur or a visible insult to be proven on the field; if the act is judged deliberate, the cover itself can be enough.
The Ley Prestianni is being described as a measure aimed at hidden insults and racism, and its first uses have already crossed competitions. During the recent Mundial, Miguel Almirón and Piero Hincapié were the first two precedents for expulsions linked to the same kind of gesture, while Vinicius Jr. later accused Gianluca Prestianni of racist insults after a goal celebration when Prestianni had his mouth covered by his hand. For Liga MX, Aguirre’s dismissal is now the first reference point.
What remains unanswered is the part the red card could not show: what Aguirre actually said, and how the review led the referee to treat the gesture as enough for a sending-off. For now, Tigres has the first Liga MX case under the new rule, and Aguirre leaves it with one red card and a precedent he did not choose to make.
