“ZC expects all contracted players to uphold the highest standards of professionalism, discipline and compliance with team protocols and anti-doping regulations,” it continued.

“A review of Williams’ record indicates a history of disciplinary issues and repeated unavailability, which has impacted team preparations and performance.

“While ZC commends him for seeking rehabilitation, withdrawal from team commitments under circumstances involving potential testing raises serious concerns regarding professional and ethical standards.”

It said it was “not feasible” to continue his national contract when it runs out on 31 December.

“Notwithstanding this, ZC sincerely acknowledges and appreciates his immense contribution to Zimbabwean cricket over the past two decades,” it added.

“Williams has played a pivotal role in some of the most significant moments in our recent history, leaving a lasting legacy both on and off the field.

“ZC wishes him strength in his recovery and every success in his future endeavours.”
