Canada’s World Cup roster includes Jayden Nelson after he replaces Marcelo Flores, who is ruled out due to injury. Multiple outlets report that Flores sustained an anterior cruciate ligament (ACL) tear during the Concacaf Champions Cup final. He undergoes surgery on June 5 to repair the injury, which leads to his withdrawal from the tournament squad. In response, Canada adds Nelson to the World Cup roster as the designated replacement. The reporting across outlets indicates the change is directly tied to Flores’s medical timeline following the operation and the need for a fit player before the competition. Channel NewsAsia, Winnipeg Free Press, and The Athletic all describe the same personnel update and the same underlying reason: Flores’s ACL injury and subsequent surgery. While details on Nelson’s role or specific match availability are not covered in the provided excerpts, the sources are consistent on the roster adjustment and the injury that prompts it.
