Three red cards in a single match. That is how the 2026 World Cup announced itself on Thursday, at the Estadio Azteca in Mexico City, where the host nation beat South Africa 2-0 in front of a roaring crowd and a refereeing crew that never quite stopped reaching into its pocket. Some context is in order: the entire tournaments in Qatar four years ago and Russia in 2018 produced four red cards apiece, across dozens of matches. Mexico and South Africa nearly equalled that haul before the opening day was done.
So the tone has been set, and it is a combative one. The opener delivered five goals, a thunderstorm that briefly interrupted proceedings, a glitzy ceremony and a running argument about how this expanded tournament will actually be officiated over its 39 days and 104 matches. Whether the early severity holds up across the competition is anyone's guess. Refereeing standards at the start of a World Cup tend to filter through to the rest of it, though, and the men with the whistles in North America appear to have arrived in a strict mood.
The red cards, and the VAR row that followed
The sendings-off went to South Africa's Yaya Sithole and Themba Zwane, and to Mexico's Cesar Montes, with Brazilian referee Wilton Sampaio at the center of it. The decision that drew the most heat was Zwane's. As Al Jazeera reported, Sampaio waved play on after Zwane's arm caught Mexico's Roberto Alvarado in the face, only to reverse course once the Video Assistant Referee summoned him to the pitchside monitor. He then produced the red, citing violent conduct.
The replays didn't make it obvious. Zwane appeared to be trying to move past Alvarado, and his hand connected as he did. South Africa's coach, Hugo Broos, made his displeasure plain afterward, suggesting the Mexican player had blocked his man and that the offense was too slight to merit dismissal. He stopped short of refusing to accept it. That is the position referees occupy, he acknowledged, and teams have to live with their calls.
It is, by now, a familiar World Cup subplot. VAR was sold as a tool to remove the howlers, and on the marginal, subjective calls it keeps producing the very arguments it was meant to settle. Thursday's incident won't be the last of its kind in this tournament. The three red cards in Mexico City fell just one short of the most ever shown in a single fixture, a mark reached at the 2006 World Cup when Portugal and the Netherlands met in a notoriously fractious last-16 tie that came to be known as the Battle of Nuremberg. That same tournament in Germany still holds the all-time red card record of 28. If the opening day is any indication, the figure is under threat.
Water breaks that nobody asked for
FIFA's other innovation arrived more quietly and went down less smoothly. For the first time at a World Cup, fixed hydration breaks were written into the rules: one per half, taken regardless of the temperature, introduced on player-welfare grounds. The trouble is what happens to the broadcast when play stops. In the United States, Fox cut to full-screen commercials during the breaks in the Mexico match, and viewers complained they had missed live action when the broadcast returned. Other broadcasters kept their cameras on the players. The experience, in other words, depended on where you happened to be watching.
Mauricio Pochettino, the United States head coach, was lukewarm on the whole idea, and said so. He doesn't see the point when conditions are good, he explained, reserving his support for genuinely extreme heat. He framed it as roughly even: useful for staff who want a window to make adjustments or address a problem, but unnecessary as a fixed feature of every game. He also admitted he hadn't watched the opener. His verdict, in the end, was that he disagrees with the breaks but doesn't think they'll meaningfully change matches. Which, frankly, is the sort of measured shrug that suggests the policy will survive its first round of grumbling.
There is a tension worth naming here. Player welfare in summer heat across North American venues is a real concern, and FIFA can hardly be faulted for taking it seriously. And yet a break imposed in mild conditions, dictated by the clock rather than the thermometer, hands the moment over to advertisers and risks killing the rhythm of a match. The governing body has bet that the trade-off is worth it. The early reviews are mixed.
South Korea's late escape in Zapopan
The second match of the day produced a comeback. South Korea, ranked 25th by FIFA, trailed Czechia and recovered to win 2-1 in Zapopan, near Guadalajara, in a game that took a long time to come alive. Both sides were jeered off at the interval after a flat opening 45 minutes. Czechia, appearing at a World Cup for the first time since that 2006 edition in Germany (the red-card tournament, as noted), took the lead in the 59th minute through a header from captain Ladislav Krejci, the product of a long throw into the box.
Then Hwang In-beom changed the game. As Al Jazeera detailed, he equalized in the 67th minute with a feinted shot that wrong-footed two defenders, then swung in the cross from the right that Oh Hyeon-gyu converted in the 80th to win it. A goal and an assist from one player, inside a quarter of an hour.
The headline, though, was about who didn't score. Son Heung-min, so often South Korea's decisive figure on the biggest occasions, had the bulk of the chances and finished none of them. He combined sharply with Lee Kang-in and Lee Jae-sung through the first half, the trio cutting through the middle with quick passing and movement, but the final touch kept deserting them. It fell to others to settle the result, and they did. South Korea controlled possession and outshot a Czech side that leaned on set pieces and a more direct, physical approach despite both teams lining up in a 3-4-3.
One detail sat oddly against the occasion. The announced crowd was 44,985 at a stadium that holds 45,664, yet whole sections in the middle of the stands sat empty, with gaps scattered elsewhere. A near-sellout on paper that looked, on camera, like something less. It is a small thing. But it is the kind of thing FIFA will be watching, given how much of this tournament's commercial story rests on filling North American venues across three countries.
What the standings mean now
After day one, Group A is split cleanly. Mexico and South Korea both have three points, the hosts ahead on goal difference, with Czechia third and South Africa, beaten and down to nine men, at the bottom. The format rewards the cautious as well as the brilliant: the top two from each of the 12 groups advance, joined by the eight best third-placed sides, into a round of 32. There is room, in other words, to recover from a poor start.
The next test comes on June 18, when Mexico face South Korea in Zapopan and Czechia meet South Africa in Atlanta. Two questions carry over from the opening: whether referees ease off after a punishing first match, and whether FIFA's water breaks settle into the background or keep irritating the people watching at home. Neither will be answered for a while. But the tournament has plenty of road left to run, and on the evidence of Thursday, it won't be a quiet one.
