The Adelaide 36ers fired Montrezl Harrell after he tested positive for cannabis in China, halting his return to the NBL.

The Adelaide 36ers have terminated Montrezl Harrell’s contract ahead of the NBL season after he tested positive for a cannabis-related substance while playing in China’s professional league. The positive test, confirmed in June 2025, led to a provisional ban and ongoing anti-doping proceedings under World Anti-Doping Agency rules, leaving Harrell unable to train or play. The club stated it had no choice but to part ways due to the uncertainty and need to finalize its roster. Harrell, a former NBA player, re-signed with the 36ers in May but is now seeking a replacement ahead of their season opener. The final outcome of the Chinese doping case remains unknown, and no official decision has been released by the NBL or relevant authorities.
