Mexico will not appeal the six-game suspension of coach Juan Carlos Osorio, the national federation announced on Friday.
FIFA banned Osorio last week for protesting a controversial referee decision in the third-place game of the Confederations Cup, leaving the coach to watch the ongoing CONCACAF Gold Cup from a stadium suite.
But Mexico, which will play the complete six games at the Gold Cup if it reaches the final, will not push back against the punishment.
The Mexico Football Federation statement said: "After having received complete documentation about the incidents during the match for fourth place in the 2017 FIFA Confederations Cup between Mexico and Portugal and having analysed the situation carefully, it has been decided to not appeal the sanctions imposed upon Juan Carlos Osorio, manager of the Mexico national team."
Mexico's Gold Cup squad, consisting mostly of second-choice players who did not play at the Confederations Cup, was booed off the pitch after a 0-0 draw with Jamaica on Thursday night.
Assistant coach Luis Pompilio Paez, overseeing the team in Osorio's absence, said he accepted the criticism.
"The fans bought the tickets, they came out to watch a team win and perform well, so we understand their frustration," he said. "We didn't perform as we should have. The result wasn't good enough.
"We created some chances with the header from [Jesus] Molina in the first half, we had the ball, we had the possession, we just didn't create enough opportunities.
"Jamaica came out with three players on the attack, they attacked with two players in the second half and in the end they attacked with one player.''
