Co-host Canada reached the 11 June 3pm ET FIFA squad lock with two slots unresolved. Marcelo Flores's ruptured ACL (anterior cruciate ligament) was confirmed, with Jayden Nelson of Austin FC favoured to replace him , . A second slot stayed disputed: broadcaster TSN reported defender Moïse Bombito out with an unhealed tibia fracture, while head coach Jesse Marsch publicly called the decision "day-by-day" 1. Canada Soccer floated Ralph Priso and Zorhan Bassong as options for the second place.
Canada open against Bosnia and Herzegovina in Toronto on Friday 12 June. Flores tore the ligament in the CONCACAF (the North American confederation) Champions Cup final, a vacancy already flagged when Nelson emerged as the leading candidate . The first hole was therefore settled in principle; the second was a live argument between a national broadcaster's reporting and the manager's public position.
FIFA's injury-replacement window closes the day before a team's first match, not at a single tournament-wide cut, so Canada's clock ran to 3pm ET on 11 June. Any player added after that point cannot be registered. That deadline is what gives Marsch's "day-by-day" line its sharp edge: a host nation finalising its 26 two days before kickoff has no competitive minutes left to bed a late call-up into the side.
