Lehmann initially signalled an intention to continue in his role after Steve Smith, David Warner and Cameron Bancroft were sent home from South Africa in disgrace for their roles in a pre-meditated plan that saw the latter attempt to alter the condition of the ball during the third Test in Cape Town.
Smith and Warner - formerly the captain and vice-captain of the team - were banned for 12 months by Cricket Australia (CA) on Wednesday, while Bancroft earned a nine-month suspension.
