Netherlands vs Morocco will be refereed by Wilton Sampaio, from Brazil.
Co-hosts Canada became the first side to book a place in the last-16 when they saw off South Africa with an injury-time goal on Sunday, while Brazil will take on Japan in Monday's early kick-off, which will be followed by Germany vs Paraguay.
It's then over to Monterrey for what - on paper, at least - should be one of the best ties of this first knock-out round.
Referee confirmed for Netherlands vs Morocco
Despite being held to a 2-2 draw in their Group F opener against Japan, the Netherlands would go on to progress as group winners following emphatic wins over Sweden and Tunisia.
That meant that Group C's second-place finishers awaited them, with Morocco finishing behind Brazil on goal difference after also claiming two wins and a draw in the opening phase of the tournament.
The referee for this match will be Wilton Sampaio.
And yes, that's the Brazilian official who sent off three players in the opening match of the tournament, when he gave South Africa duo Yaya Sithole and Themba Zwane, plus Mexico's Cesar Montes, red cards during the co-host's 2-0 victory at the Azteca.

Sampaio's other match in the tournament was a quieter affair, as he oversaw Norway's 3-2 victory over Senegal without having to dole out any cards.
England fans may also recognise the 44-year-old from England's 2-1 quarter-final defeat to France at the last World Cup in 2022.
Sampaio will be joined by his countrymen Bruno Pires and Bruno Boschilia as assistant referees.
Chile's Cristian Garay will be the fourth official for this one, while the reserve official will be another Chilean in Jose Retamal.
Details of the VAR crew for this one are yet to be confirmed at the time of writing.
