Marcelo Flores is a 22-year-old attacking midfielder of Mexican and English heritage who represents Canada internationally. He ruptured his ACL in the CONCACAF Champions Cup final — a non-contact injury — just one day after being named in Canada's 26-man World Cup squad, ruling him out of the tournament and forcing Jesse Marsch to name a replacement before the 12 June opener against Bosnia and Herzegovina .

Flores was Born in England and raised in Mexico, making him eligible for three national teams before he committed to Canada in 2022. He plays his club football for Arsenal in England — a product of the same Hale End academy that produced Folarin Balogun — and has been one of the more exciting young attacking midfielders in Canada's program. His inclusion in the World Cup squad reflected the coaching staff's confidence in him despite his young age.

The timing of his injury — a day after selection — is one of the more unfortunate pre-tournament stories of the 2026 cycle. Canada were already managing a degree of uncertainty in their attacking options, and losing a creative midfielder of Flores's profile to a long-term injury just days before the tournament deepens the challenge for Marsch's squad. ACL ruptures typically require nine to twelve months of recovery, meaning Flores will miss the bulk of the 2026-27 club season as well.
