Who are the officials and where do they come from?
The man in the middle will be Portuguese official Joao Pinheiro, a very experienced referee who has previously taken charge of games in Portugal's Primeira Liga, the Champions League, the Europa League and for Tottenham Hotspur's 2025 Super Cup defeat against Paris Saint Germain.
It will be his first appearance at the tournament, although he has been on FIFA's list of referees since 2019, having first refereed a senior international match back in 2019, when he was put in charge of a match between Brazil and Panama.
He is used to dealing with high profile players, including the likes of Cristiano Ronaldo and Sadio Mane, as he's also a regular in the Saudi Pro League, as well as the Egyptian Premier League.
However, he is very fond of dishing out cards, handing out a total of 1,980 yellows and 45 reds from the 440 games he's refereed during his career to date, averaging around five yellows per match.
Helping him out in this evening's match at Sofi Stadium in Los Angeles will be his Portuguese compatriots Bruno Jesus and Luciano Maia.
They will be helped out by another Portuguese member of staff, Tiago Martins, who will be the match's Video Assistant Referee (VAR).
The officials will be joined by Japanese pair Yusuke Araki, who will be this evening's fourth official, and Jun Mihara, the reserve assistant referee.
Switzerland will be hoping for a better outcome than in their opening fixture when they were pegged back by Qatar late on through Miro Muheim's equaliser, after taking the lead early in the match through a Breel Embolo penalty.
Bosnia are in a similar situation, having scored first against hosts Canada, before conceding a leveller in the 78th minute.
A win for either side will likely be enough to seal qualification from the group stages.
