Marcelo Flores, the 22-year-old Canadian midfielder, suffered a torn anterior cruciate ligament (ACL) in his right leg on May 30, 2026, during the Concacaf Champions Cup final while playing for Tigres UANL [1, 2, 3]. Flores was substituted on in the 63rd minute and injured his ACL 15 minutes later in the 77th minute of the match [3].

Flores publicly confirmed the injury on May 31 via social media, writing, "My ACL is gone. I wanted to say thank you to everyone and all the messages. I haven't been on my phone or checked messages, but I promise to get around to everyone and I really appreciate the concerns. I'll be back stronger" [1]. He also posted in Chinese, expressing how difficult the time is and vowing to return stronger [3].

Canada’s head coach Jesse Marsch expressed devastation over the news, saying, "We are devastated by the news." He added, "Because this does not look like a minor injury, but we are with him in spirit" [1, 3].

Flores was named in Canada’s 26-man squad just days earlier on May 29 [1, 2, 3]. Born in Canada to a Mexican father, Flores originally played for Mexico but switched allegiance to Canada earlier in 2026 [1, 2, 3].

As of May 31, Canada had not decided who will replace Flores in the squad [3].

Canada is scheduled to play a friendly match against Uzbekistan on June 1 in Edmonton, followed by its World Cup opener against Bosnia and Herzegovina on June 12 in Toronto [1, 2].
