In addition, the period of Ineligibility calculated under this Article 10.2.4.1 may be reduced to one (1) month if the Athlete satisfactorily completes a Substance of Abuse treatment program approved by SAIDS.
The Athlete accepted a voluntary provisional suspension starting on 15 May 2025 and completed a Substance of Abuse treatment program which was approved by SAIDS. Consequently, the period of Ineligibility was reduced to one (1) month, effective from 15 May 2025, until and including 15 June 2025.
