Hincapié was not reported as saying anything specific that’s publicly confirmed; the reporting only says he spoke to Santiago Giménez while covering his mouth, which led Giménez to alert the referee and the red card to be reviewed.

What’s known

  • The incident happened late in Ecuador’s match against Mexico.
  • Hincapié appeared to address Giménez with his hand over his mouth.
  • Giménez then informed the referee, which triggered the review and sending-off.

What isn’t confirmed

  • No reliable report in the available coverage quotes the exact words Hincapié used.
  • There has also been no indication in the coverage that he made discriminatory remarks.

TL;DR: the exact phrase hasn’t been publicly confirmed; all that’s reported is that Hincapié mouthed something to Giménez, who complained to the referee.
