Nico Williams is most likely not playing because he has been dealing with a recent hamstring issue, and reports around Spain’s June 2026 matches say he was being managed carefully rather than ruled out long-term. In some match previews, he was listed as available but left on the bench or used in a limited role as a precaution after recovery.

What the reports say

  • He suffered a hamstring injury near the end of the club season.
  • Medical updates said the problem was not as serious as first feared and that he was expected back fairly quickly.
  • Later reports said he was ready to start again, which suggests the “not playing” situation was likely about rotation, fitness management, or match-by-match selection rather than a major setback.

Most likely reason

The simplest explanation is fitness management after injury. Coaches often avoid rushing a winger like Nico Williams back for a full 90 minutes if he has only recently returned, especially in a tournament setting.

Current read

If you saw him absent from a lineup, it does not sound like a long-term injury crisis from the reports available; it looks more like a cautious return and squad rotation decision.
