After all, that medal came after years of struggle while working two jobs to support his family and chasing his sport.
Fast forward to 2026, and that same athlete is now facing a very different headline. On May 8, Siqueira was handed a two-year suspension after repeated failures to meet anti-doping testing requirements. The International Testing Agency confirmed that he committed three “whereabouts failures” within a 12-month period, which under World Anti-Doping rules is treated as a violation even without a positive drug test.
According to the ITA, “Maicol de Andrade Siqueira has been sanctioned with 2 years of ineligibility for an ADRV under Article 2. 4 of the WT Anti-Doping Rules (WT ADR)…. ” However, Siqueira’s suspension runs from January 19, 2026, to January 18, 2028.
The ITA also confirmed that his individual results from July 2025 onwards will be disqualified. For now, Siqueira did not challenge the ruling, though it can be appealed to CAS. It remains unclear whether he was actively competing when tests were missed.
