Overview

• Harrell is under a provisional ban after testing positive for carboxy THC from an April 2025 sample taken while he was playing in China.
• China’s Anti-Doping Agency announced the positive finding on June 25, with any binding sanction yet to be determined.
• The club said he is not permitted to train or play and cited the lack of a clear timetable as the reason for ending his deal.
• The decision lands just before Sunday’s home opener against the Brisbane Bullets after he was already held out of a recent exhibition in Sydney.
• Adelaide will pursue a replacement with two import slots now open following Bryce Cotton’s Australian citizenship, as Harrell thanked fans and voiced frustration on social media.
