Glenn Maxwell has decided to withdraw himself from Australia's T20I squad, citing the need to deal with mental health difficulties.
Australia have confirmed the inclusion of hard-hitting batsman D'Arcy Short as the replacement player for the game against Sri Lanka.
"Glenn Maxwell has been experiencing some difficulties with regards to his mental health. As a result, he will spend a short time away from the game," the team psychologist Dr. Michael Lloyd said.
"Glenn was proactive in identifying these issues and engaging with support staff."
Maxwell has been a constant member of Australia's white-ball setup and endured a torrid summer with the bat during the World Cup in England and Wales where he made 177 runs in 10 innings at an ordinary average of 22.12.
The 31-year-old recently returned to form in emphatic fashion by blasting a 28-ball 62 in his side's thumping win over Sri Lanka in the opening T20I.
His decision to step away from the sport temporarily was warmly received by the executive general manager of the national teams, Ben Oliver, who affirmed Cricket Australia's focus on sustaining the mental wellbeing of players.
"The well-being of our players and staff is paramount. Glenn has our full support. Cricket Australia will work collaboratively with Cricket Victoria's support staff to ensure Glenn's well-being and his reintegration into the game.
"We ask that everyone gives Glenn and his family and friends space; and respects their privacy at this time."
"He's a special player and an important part of the Australian cricket family. We hope to see him back in the team during the summer. It's important we look after Glenn and all our players," Oliver added.
