Darren Lehmann will have a heart bypass operation on Saturday after having been admitted to hospital with chest pains.
The popular former Test batsman was on the Gold Coast on the occasion of his 50th birthday watching his son Jake take part in the contest between Cricket Australia XI and England.
The health scare prompted Lehmann to be rushed to the hospital where doctors have suggested the need for bypass surgery.
“Former Australia batsman and coach Darren Lehmann will undergo bypass surgery on Saturday after suffering chest pains on the Gold Coast today,” Cricket Australia wrote on its website.
The two-time World Cup-winner is currently resting in hospital where he sent out a message thanking his well-wishers.
"I would like to thank everyone in the Australian cricket family for their concern," Lehmann said.
"I am receiving the best of medical care and am confident I'll be back on my feet soon."
Lehmann played 117 ODIs for Australia and later coached the national side from 2013 to 2018.
He quit from the coaching position in the aftermath of the notorious ball-tampering scandal that rocked the game in the country.
Lehmann returned in the coaching capacity this summer with the Big Bash League franchise Brisbane Heat and is set to be involved in a similar role for Northern Supercharges in the inaugural Hundred competition.
