Tim Paine is set to miss Australia's upcoming Ashes series against England after Cricket Tasmania announced he is taking a leave of absence from all forms of cricket "for the foreseeable future".
The 36-year-old stepped down from his role as Australia's Test captain last week over an historical investigation into lewd texts sent to a former Cricket Tasmania colleague in 2017.
Paine received the full backing of his team-mates and was still in Australia's Ashes squad to face England, with the first Test scheduled to begin on December 8.
However, Paine has pulled out of Tasmania's one-day match against Western Australia on Friday and is now expected to be out of contention for the Ashes series.
A statement released by Cricket Tasmania on Friday read: "Following discussions over the last 24 hours, Tim Paine has advised Cricket Tasmania that he will be taking a leave of absence from all forms of cricket for the foreseeable future.
"Tim's decision makes him unavailable for selection for today's Marsh One-Day Cup match against Western Australia. His place in the squad will be taken by Charlie Wakim.
"Cricket Tasmania will continue to support Tim and his family both professionally and personally over the summer."
Paine's manager James Henderson added in a Twitter post that he is worried about the veteran wicketkeeper's mental state, as well as his wife Bonnie after details of the scandal became public a week ago.
"Confirming that @tdpaine36 is stepping away from cricket for an indefinite mental health break," Henderson posted.
"We are extremely concerned for his and Bonnie's well-being and will be making no further comment at this time."
Paine underwent neck surgery in September before returning to action for Tasmania's second XI against South Australia earlier this week.
Pat Cummins and Steve Smith have reportedly been interviewed by Cricket Australia (CA) amid ongoing speculation the pair will step in as captain and vice-captain respectively.
