Australian coach Darren Lehmann to resign in the wake of ball-tampering scandal - reports

Darren Lehmann is set to become the first casualty of the Australian cricket teams' ball tampering scandal during the third test in South Africa.

The Telegraph in the UK is reporting Lehmann is preparing to stand down effective immediately.

Captain Steve Smith tried to create distance between Lehmann and the ball-tampering, laying the blame on himself and his leadership group, but the coach was seen to be communicating with 12th man Peter Handscomb via walkie talkie.

Minutes later Handscomb was seen on the park, seemingly informing Cameron Bancroft that his actions had been uncovered by the host broadcaster.

Smith has since been suspended for the final test of the series and his role as skipper has been described as untenable by former players such as Shane Warne and Jason Gillespie.

David Warner is reportedly set to lose his vice-captaincy as part of the on-going fallout.

Cricket Australia have hit out at the reports claiming speculation on Lehmann stepping down is just that, speculation and nothing will happen until after CEO James Sutherland touches down South Africa on Wednesday (NZT).
