After Steve Smith and Cameron Bancroft, David Warner has also accepted the sanctions imposed on him by Cricket Australia (CA) for his involvement in the ball-tampering controversy during the third Test against South Africa in Cape Town.

On Thursday, Warner announced that he would not be challenging the sanctions – a 12-month ban from domestic and international cricket and a lifelong bar from being in a leadership position in the Australian national team.

Like Smith and Bancroft, Warner tweeted his decision: “I have today let Cricket Australia know that I fully accept the sanctions imposed on me. I am truly sorry for my actions and will now do everything I can to be a better person, teammate and role model.”

Bancroft was caught on TV cameras trying to alter the condition of the ball using a yellow-coloured object during the second session on day three of the Cape Town Test. After the day’s play, Smith and Bancroft admitted to having used a tape on the ball, but the object was later found to be sandpaper.

The International Cricket Council soon handed a one-match suspension to Smith, along with fining him 10 per cent of his match fee, while Bancroft was fined 75 per cent of his match fee and given three demerit points.

Last week, in a press conference in Sydney, Warner said that he had resigned himself to the fact he might never play for Australia again.

“To the fans and the lovers of the game who have supported and inspired me on my journey as a cricketer, I want to sincerely apologise for betraying your trust in me,” Warner said. “I have let you down badly. I hope in time I can find a way to repay you for all you’ve given me and possibly earn your respect again.

“There’s a tiny ray of hope that I may one day be given the privilege of playing for my country again but I’m resigned to the fact that that may never happen again.”
