A Harsh Reminder of Strict Liability. When a player dopes deliberately to chase an edge, he deserves the book thrown at him. But when it’s a prescribed medication for genuine weight management that slips through the cracks? That’s a different story — one that still ends in real consequences.
The Lions Rugby Company confirmed on 14 May 2026 that the South African Institute for Drug-Free Sport (SAIDS) has sanctioned their prop Asenathi Ntlabakanye with an 18-month ban for an anti-doping rule violation. The suspension, which took effect from 13 May 2026, rules the 27-year-old tighthead prop out of this weekend’s United Rugby Championship clash against Munster and, most painfully, the entire 2027 Rugby World Cup cycle.
Here’s the clear context: Ntlabakanye had been battling weight issues. After significant hard work — including tough farm training sessions — he managed to shed kilos and earn his Springbok opportunity. Under medical advice from a specialist physician, he was prescribed Anastrozole (a hormone and metabolic modulator, not classified as performance-enhancing) early in 2025 specifically for weight management. He also used DHEA (a prohibited anabolic agent) under medical supervision, believing it was permitted because doctors had approved it. He self-declared both substances transparently on his testing forms and made no attempt to hide anything.
He tested positive for Anastrozole in an out-of-competition sample. Although DHEA did not appear in the test, his honest declaration triggered the second charge. SA Rugby has publicly stated that Ntlabakanye acted in good faith, followed medical due process, and sought no unfair advantage. The Independent Doping Tribunal imposed 18 months — on the lower end of the possible sanction — acknowledging mitigating factors such as lack of intent.

This was not muscle-building doping. There were no secretive injections aimed at adding size or power. It was a professional player and his medical team attempting to manage legitimate weight concerns in one of rugby’s most demanding positions, only to fall foul of anti-doping’s uncompromising strict liability rule: if a prohibited substance is in your system, you are responsible — doctor’s note or not.
The Real Cost
• Misses crucial Lions and Springbok build-up matches during a critical period.
• Likely forfeits match fees, bonuses, and other earnings.
• A devastating setback for a young prop who had turned his career around through dedication and hard graft.
The Lions, together with MyPlayers – The Rugby Players’ Organisation, will now deliberate on next steps (including any possible appeal) while continuing to support the player through the process. That is the correct and humane approach.
But the bigger lesson for South African rugby must be crystal clear:
Players must take ultimate ownership of what goes into their bodies. Medical teams and doctors advising professional athletes must triple-check WADA and SAIDS rules and secure Therapeutic Use Exemptions (TUEs) well in advance. Good intentions and legitimate prescriptions do not override the rules — even when the goal is simply weight management.

This case stings precisely because it feels more like a failure of medical oversight than deliberate cheating. Ntlabakanye was transparent from the start. He wasn’t chasing bulk or shortcuts to stardom. Yet the ban stands. It is a brutal but necessary reminder that in elite sport, the line is zero tolerance.
No further comment will be made by the Lions or the player until the process is concluded. That is their right. But the rugby public deserves to see this for what it is: an accidental violation rooted in legitimate weight management efforts, not malice — and a powerful warning that even clean intentions can cost a career if protocols are not airtight.
Clean rugby demands vigilance from players, support staff, unions, and medical teams alike.
