Either Uzebkistan or Colombia could jump to the top of Group K with a win today.
Despite leading and being the favourites on paper, Portugal only managed to draw with DR Congo, which opens up the group completely.
Next up is Uzbekistan vs Colombia, but who is on referee duty for the clash at Mexico City Stadium?
Referee for Uzbekistan vs Colombia
Anthony Taylor will be the referee for this World Cup 2026 tie in Group K.
He's a familiar name and face for fans of the Premier League, having now officiated 432 matches in the English top flight.
Taylor has also now refereed 42 matches in the Champions League, and is appearing at his second World Cup after taking care of two games at the 2022 tournament in Qatar.
Across 550 games in his career, Taylor has shown 1,997 yellow cards at an average of 3.63 per game (as per WhoScored) — that's a figure ever so slightly higher than your standard referee, but you would hardly call him a harsh referee.
Indeed, his red card rate is lower than most, with just 87 shown at a rate of 0.16 per game.
Alongside Taylor for the Uzbekistan vs Colombia game will be Gary Beswick and Adam Nunn as assistants on each touchline.
Costa Rican pair Juan Gabriel Calderón and Juan Carlos Mora are the fourth official and reserve assistant referee, respectively.
Ivan Bebek, of Croatia, will lead the VAR team for the game, while another Premier League ref, Jared Gillett, is in the room as his assistant.
