The ITA, on behalf of WBSC, confirms that the athlete Jean Carlos Herrera Malambo has agreed¹ to the consequences imposed for his anti-doping rule violation (ADRV).
As previously reported, the athlete tested positive for the prohibited substance stanozolol after providing an out-of-competition sample on 8 November 2025. He was provisionally suspended on 20 January 2026.
The athlete did not challenge the ADRV and agreed with the consequences proposed by the ITA. Due to his early admission, the athlete was entitled to a one-year reduction of the otherwise four-year period of ineligibility usually imposed for an ADRV for the presence of stanozolol as set forth in article 10.8.1 of the WBSC anti-doping rules.² Accordingly, the case was resolved via an acceptance of consequences.
The athlete’s period of ineligibility is from 20 January 2026 until 19 January 2029. In addition, all the athlete’s individual competitive results from 8 November 2025 are disqualified, including forfeiture of medals, points and prizes.
Parties with a right of appeal may challenge the decision before the appeals division of the Court of Arbitration for Sport (CAS) in accordance with article 13.2.3 of the WBSC anti-doping rules.
The ITA will not comment further on this case.
¹ Athletes have the right to choose not to have their case referred to a hearing panel. In these instances, the anti-doping organisation will assess the athlete’s case file and establish the applicable consequences pursuant to the anti-doping rules and the athlete will have the right to accept the proposed consequences. If the athlete refuses the proposed consequences, the case is transferred to a hearing panel. This resolution mechanism is provided for in articles 8.3.1 and 8.3.3 of the WBSC anti-doping rules and 8.3 of the World Anti-Doping Code. It is commonly referred to as an agreement on consequences and is deemed a WBSC/ITA decision. The athlete’s National Anti-Doping Organisation and the World Anti-Doping Agency have the right to appeal the agreement on consequences before the competent appeal body.
² Article 10.8.1 of the WBSC anti-doping rules (and World Anti-Doping Code) provides for a one-year reduction for certain ADRVs based on early admission and acceptance of sanction. This applies where an athlete after being notified by WBSC/ITA of a potential ADRV that carries an asserted period of ineligibility of four (4) or more years, admits the violation and accepts the asserted period of ineligibility no later than twenty (20) days after receiving notice of an ADRV charge. Where the athlete receives the one-year reduction under Article 10.8.1, no further reduction in the period of ineligibility is allowed.
