Steve Smith and David Warner have been banned for 12 months over the Australia ball-tampering scandal, according to reports.
Cameron Bancroft, the batsman who was caught on camera attempting to use tape and dirt to change the condition of the ball during the third Test against South Africa, has reportedly been banned for nine months.
The severe punishments are expected to be confirmed by Cricket Australia on Wednesday.
All three disgraced players involved have been sent home ahead of the fourth and final Test in Johannesburg, with Matt Renshaw, Glenn Maxwell and Joe Burns called up as replacements.
Tim Paine, who took over from Smith as captain mid-match in Cape Town as the furore began to unfold, was officially appointed as captain of the Test team on Tuesday.
Smith and Australia vice-captain Warner have also relinquished the captaincy of their Indian Premier League sides.
