América vs. Pumas in the first leg of the Clausura 2026 quarterfinals remains mired in controversy, as there is now talk of an improper lineup on the part of the azulcrema side.
The focus of the incident centers on Sebastián Cáceres’ injury, as he was unable to continue on the field after the concussion protocol was activated due to a blow to the face.
Before the hit, Jardine and his coaching staff were planning to make adjustments to their setup, including bringing on Miguel Vázquez, but after the Uruguayan went down they decided not to go through with the substitution.
Given this, Pumas reportedly filed a protest over an improper lineup, since according to the university side, the América defender had already left the field and was pushed to return so the protocol could be applied.
Is it an improper lineup?
According to “El Cantante” Guerrero, it is not an improper lineup, because “El Shoker” NEVER completely leaves THE FIELD OF PLAY. So by the rules of the game, that is NEVER considered a completed substitution. There is nothing against the rules in this action. Cáceres’ concussion substitution is carried out, and that’s it.”
