David Warner has also been banned from leadership positions in Australian cricket for life while Smith and Bancroft were banned from leadership positions for 12 months after completing their ban. It means Australia will have a new captain for the upcoming World Cup in 2019.
The Indian Cricket Board BCCI has barred Steve Smith and David Warner from taking part in this year's Indian Premier League after CA found them guilty of ball-tampering charges. Their respective teams Rajasthan Royals and Sunrisers Hyderabad will be allowed to replace them. RR and SRH will be able to pick from players who went unsold at the 2018 IPL Auction.
The trio will be allowed to play club cricket and were encouraged by CA to do so "to maintain links with the cricket community." They were also "required to undertake 100 hours of voluntary service in community cricket", said an ESPNCricinfo report.
They can challenge the ban within seven days.
Smith, Warner and Bancroft were found to have breached article 2.3.5 of the CA Code of Conduct, which relates to conduct at any time that is contrary to the spirit of the game, unbecoming of a representative, harmful to the interests of the game, or bringing the game into disrepute.
The incident took place during South Africa's innings on Saturday afternoon when Bancroft was seen on television holding a foreign object while rubbing the ball, before hiding the object in his pocket, then inside his trousers.
As soon as the incident was shown on the venue's big screen, the player was questioned in the presence of his captain by the two on-field umpires, Richard Illingworth and Nigel Llong, who, along with third umpire Ian Gould and fourth umpire Allahudien Palekar, later charged Bancroft.
The plan to alter the condition of the ball had been made at the lunch break on day three between senior players from Australia without the consent of the coaching staff, according to Smith.
Smith and Bancroft owned up to the offence at the press conference after play on the third day, and while Warner was not initially at the forefront of the scandal, a view is emerging that he had hatched the idea to tamper the ball and delegated it to his opening partner Bancroft, with Smith's approval.
