The boxing world was shaken today after Ring Magazine reported that former heavyweight champion Joseph Parker has reportedly tested positive for cocaine in a VADA-administered drug test. According to the post, the test was taken on the same day as his recent defeat to Fabio Wardley, adding another layer of scrutiny to an already difficult night for the New Zealand boxer.
The Initial Findings
The report states that Parker’s A-sample came back positive for cocaine, a prohibited substance under VADA regulations. While the news has circulated rapidly through the boxing community, it is important to emphasize that the finding is initial. Only the A-sample has been tested so far.
As standard protocol dictates, Parker now has the right to have his B-sample tested. This step is crucial, as discrepancies between the A- and B-samples, while rare, are not impossible.

Team Parker’s Reaction
According to Ring Magazine’s post, two sources close to Parker’s team expressed dismay at the reported findings. No official statement from Parker or his management has yet been released, but the reaction from those near his camp suggests shock and concern rather than acceptance.
This response hints that the team may contest or question the result, pending further analysis of the B-sample.

Why This Matters
Doping allegations, especially involving recreational drugs, carry serious consequences in professional boxing. Even when performance enhancement is not the central issue, a positive test can lead to consequences such as:
- Suspensions
- Fines
- Overturned fight results
- Long-term reputational damage
For a fighter of Parker’s stature, the implications extend far beyond the ring. Public image, future matchups, and endorsement opportunities all hang in the balance.
Next Steps
The key development now is the testing of the B-sample. Until that comes back, nothing is final. The boxing community will be watching closely for clarity in the coming days or weeks.
If the B-sample confirms the A-sample’s result, the fallout could alter the trajectory of Parker’s career. If not, the narrative shifts dramatically, and questions about testing accuracy or procedural issues could take center stage.
