The former Australian vice-captain said that the scandal is a “stain on the game we all love and I have loved since I was a boy”.
David Warner, who has been banned by Cricket Australia (CA) for a year for ball-tampering, apologised to fans for the "mistake" on Thursday.
Warner tweeted: “To cricket fans in Australia and all over the world: I am currently on my way back to Sydney. Mistakes have been made which have damaged cricket. I apologise for my part and take responsibility for it. I understand the distress this has cause the sport and its fans. Its a stain on the game we all love and I have loved since I was a boy. I need to take a deep breath and spend time with my family, friends and trusted advisers. You will hear from me in a few days. (sic)”
Warner was barred from playing in the Indian Premier League (IPL) on Wednesday. His team SunRisers Hyderabad (SRH) had announced on Twitter that Warner has stepped down as the captain and that they would be naming a replacement soon.

Steve Smith is also expected to hold a press conference on Thursday.
Meanwhile, Cameron Bancroft, who was caught on camera scraping the ball with a yellow object, was suspended from international cricket for nine months.
Earlier, Cricket Australian had suspended the trio from playing in the final Test match. They have been given seven days to appeal against the decision.
Both, Smith and Warner stepped down as captain and vice-captain, respectively, during the third Test against South Africa when the scandal came to light.
Smith, who had led the national side since 2015, confessed in Cape Town on Saturday that the ball-tampering incident had been orchestrated by himself and senior players.
Bancroft was tasked with implementing the plan and was duly caught on camera using a tape to tamper the ball.
