Earlier in the day Steve Smith and Cameron Bancroft both repeated their apologies for their part in the Australia ball-tampering scandal as cricket's worldwide governing body announced a wide-ranging review into the behaviour of players.
When Cameron Bancroft and Steve Smith admitted the attempt to cheat for the first time in the post-match press conference on the third day of their third Test match between Australia and South Africa, Smith was clear in his revelations that the team's leadership group knew about the idea. "After seeing events in the media today with Steve Smith and Cameron Bancroft, the feeling is that Australian cricket needs to move forward and this is the right thing to do". Bancroft, the player who was caught actually tampering with the ball, too was suspended for nine months.
Speaking at a press conference, Lehmann said: "I'm ultimately responsible for the culture of the team and I've been thinking about my position for a while".
"My family and I got a lot of abuse over the last week".
Smith and Bancroft fought back tears as they faced the media, with former captain Smith in Sydney and Bancroft in Perth.
"To all of my teammates, fans of cricket all over the world and all Australians who are disappointed". They have made a mistake as everyone, including myself, has made mistakes in the past. It is something I will regret for the rest of my life. I panicked in that situation and I'm very sorry.
"I understand the distress this has caused the sport and its fans", the opening batsman wrote. "It's a stain on the game we all love and I have loved since I was a boy".
The yellow tape Bancroft was captured on camera rubbing against the ball, and then hiding down the front of his pants, was in fact sandpaper, CA revealed.
"I lied. I lied about the sandpaper", the 25-year-old told reporters. "I feel like I've let everyone down in Australia".
"While appreciating the work Steve Smith has done in partnership with us to support cricket for all Australians, in light of recent circumstances we have concluded our current arrangement with Steve as a sporting ambassador", the lender said in a statement.
"As I stated before I had no prior knowledge of the incident and do not condone what happened".
"They were that nice to us in New Zealand and we were that uncomfortable", he said after Australia's seven-wicket victory.
Smith and Warner have also been banned from taking part in this year's Indian Premier League, although the England and Wales Cricket Board is not taking a view at this stage - Bancroft is Somerset's overseas player for the coming season.
"What happened down there has certainly created additional urgency that something needs to be done as quickly as possible", chief executive David Richardson said on Thursday.
Matt Renshaw, Glenn Maxwell and Joe Burns have been called up as replacements ahead of Friday's fourth and final Test in Johannesburg.
