David Warner is eligible to be the captain of Sydney Thunder. The Cricket Australia (CA) has cleared lifetime captaincy ban after the ball tempering saga in Cape Town back in 2018.

David Warner already has announced retirement from international Cricket and is available only in T20 leagues around the world. A three-memeber panel presented Warner's case and made a decision on this.

The panel – Alan Sullivan KC, Jeff Gleeson KC and Jane Seawright – found unanimously that Warner had met all criteria to have the 2018 ban lifted with that decision effective immediately.

"The respectful and contrite tone of his (Warner’s) responses, as well as the content impressed the Review Panel and led it to the unanimous view that he was sincere and genuine in acknowledging responsibility for the conduct and in his statement that he had extreme remorse for his conduct," the panel says in its decision published today.

"Mr Warner’s conduct and behaviour since the imposition of the sanction has been excellent and he appears to have made a substantial change, one example of which is that he no longer sledges or tries to provoke the opposing team.

"The Review Panel is more than satisfied that Mr Warner will not engage in any conduct similar to that which occurred in 2018 which resulted in the sanction and that the sanction has thus had the relevant quality of specific deterrence."

Warner has a record of successful captaincy in T20 leagues as IPL's Sunrisers Hyderabad won their one and only title under his captaincy back in 2016. As he's in the squad of Sydney Thunder, he might be in the mix to become Thunder's new captain.
