Springbok and Lions prop Asenathi Ntlabakanye has been handed an 18-month ban following an anti-doping rule violation, a verdict delivered by the Independent Doping Tribunal Panel (IDHP). This decision comes after a lengthy wait and marks a significant setback for the 27-year-old's career, as it rules him out of crucial competitions, including the 2027 Rugby World Cup in Australia.

The doping violation involved two prohibited substances. Last year, Ntlabakanye tested positive for Anastrozole, a hormone and metabolic modulator, during an out-of-competition test conducted on 22 May 2025. While this substance is classified as 'non-performance-enhancing' and was reportedly prescribed by a specialist physician early in 2025 for medical reasons, the situation was further complicated by Ntlabakanye's voluntary disclosure. He revealed, in good faith, that he had also taken dehydroepiandrosterone (DHEA), which is categorized as a 'non-specified' and 'performance-enhancing' anabolic steroid. Consequently, he was formally charged on 9 September 2025, for both the presence and use of Anastrozole and the use of DHEA.

Under the principle of strict liability, athletes bear ultimate responsibility for any substances found in their system, irrespective of intent or prescription. The IDHP ruled an 18-month period of ineligibility for Ntlabakanye, which officially commenced on 13 May 2026. This ban means he will be ineligible to participate in rugby until 13 November 2027, effectively making him unavailable for the 2027 Rugby World Cup and immediately ruling him out of the Round 18 United Rugby Championship fixture against Munster that also began on the ban's effective date.

In addition to the playing suspension, Ntlabakanye faces retroactive financial penalties. The IDHP has ordered the disqualification of all his individual competitive results and benefits, including player-of-the-match awards, personal accolades, match fees, and bonuses. This disqualification is effective from 22 May 2025, the date his sample was collected, meaning he will be required to forfeit income earned during the period he continued to play after his initial positive test. Importantly, this disqualification is limited to his individual results and benefits and does not extend to team results.

The Lions Rugby Company has confirmed receipt of communication from the South African Institute for Drug-Free Sport (SAIDS) regarding the sanction. In their statement, the Lions expressed their commitment to supporting Ntlabakanye through the process, stating, “The Lions Rugby Company, together with MyPlayers – The Rugby Players’ Organisation, will deliberate on the appropriate next steps.” They also indicated that no further comment would be made by either the club or the player until the process concerning the way forward has concluded.

Ntlabakanye, SAIDS, World Rugby, and the World Anti-Doping Agency (WADA) have a 21-day window to file an appeal against the sanction to the Court of Arbitration for Sport (CAS). However, the likelihood of the verdict being overturned is considered low.

This ban represents a considerable setback for Ntlabakanye, who had earned four Test caps last season and was widely regarded as a strong contender for the Springbok World Cup squad. A mainstay at the Lions since 2020, he had recently completed a rigorous fitness and conditioning programme and was reportedly in the best shape of his life when the news of his positive tests became public. While there was some leniency, as the ban could have been as long as four years, this 18-month suspension is nonetheless a potentially career-defining decision.
