Overview
- Kubo left the pitch after a heavy challenge that struck his left knee and he requested a substitution during the second half of the match.
- Team staff moved him from the stadium in a wheelchair and he was later seen favoring his left leg at the team lodging.
- The Japan Football Association said Kubo underwent local hospital examinations but that formal test results were not yet available to the association.
- A later team update reported Kubo had an MRI that confirmed a left‑knee injury, he missed team training, and medical staff said he will remain with the squad rather than depart.
- Kubo is 25 and plays for Real Sociedad, and his injury adds to recent fitness concerns for Japan ahead of their next group match where his absence would reduce the team's attacking options.
