Overview

• Álvarez returned a positive test for the prohibited diuretic Canrenon after the Europa League semi-final first leg against Manchester United in May.
• He accepted a provisional suspension on June 2, which is credited toward the penalty, and he may resume team training from February 2, 2026.
• UEFA’s ruling notes the substance was taken without intent, reflecting the player’s account that it stemmed from a medication used for hair loss after prior cancer treatment.
• Athletic Bilbao said the medication in question belonged to Álvarez’s partner, corroborating the player’s explanation presented to the committee.
• The timeline means the defender will miss Athletic’s early Champions League fixtures, including the October trip to Borussia Dortmund.
