Overview

• The suspension runs until April 2, 2026, following the voluntary provisional ineligibility that began on June 2.
• Álvarez has said the adverse result came from a hair-loss treatment, and Athletic Club is backing his defense under confidentiality rules.
• UEFA opened disciplinary proceedings on June 10, investigators reviewed the case, and the disciplinary body issued its decision on Aug. 19.
• The ban tightens Athletic’s center-back options for league and Europe, with Dani Vivian and Aitor Paredes the remaining senior choices.
