Tim Paine took over the Australian test cricket team captaincy following one of the country's biggest and and most embarrassing international scandals.

He's lost it following a more personal indiscretion.

Paine quit as test captain on Friday after being investigated by Cricket Australia for sending explicit text messages to a female co-worker four years ago.

Veteran wicketkeeper Paine was named in a News Corp. report as being at the center of the sexting scandal. The 36-year-old Paine appeared before media on Friday in Adelaide to announce he was resigning the captaincy but wanted to remain a member of the test squad.

The announcement comes less than three weeks before the Dec. 8 start in Brisbane of the five-test Ashes series against England.

Paine, who underwent surgery in September to repair a pinched nerve in his neck and isn't a certainty to be a starter in the Ashes series, became test captain in March 2018 after Steve Smith lost the role following the sandpaper ball-tampering scandal in South Africa.

During the third test match against South Africa at Newlands in Cape Town, Cameron Bancroft was caught by television cameras trying to rough up one side of the ball with sandpaper. Smith and vice-captain David Warner were found to be involved and all three received sanctions from Cricket Australia, and when Smith was dumped as captain, Paine took charge.

Until Friday.

“It’s an incredibly difficult decision, but the right one for me, my family, and cricket,” Paine said. “As a background on my decision, nearly four years ago, I was involved in a text exchange with a then-colleague.

“At the time, the exchange was the subject of a thorough CA integrity unit investigation, throughout which I fully participated in and openly participated in. Although exonerated, I deeply regretted this incident at the time, and still do today."

The messages date to 2017, months before Paine was recalled to the test team after a seven-year absence.

Cricket Australia's statement said its board had accepted Paine's resignation and will look to appoint a new test captain.

“Tim felt it was in the best interests of his family and Australian cricket to take this decision to step down as captain," CA board chairman Richard Freudenstein said. “While the board acknowledges an investigation cleared Tim of any breach of the code of conduct regarding this matter some years ago, we respect his decision.

“CA does not condone this type of language or behavior. Despite the mistake he made, Tim has been an exceptional leader since his appointment and the board thanks him for his distinguished service."

Cricket Australia said Paine "will continue to be available for selection in the test team through the Ashes summer.” He was among the 15 players named earlier this week for the Ashes.

Paine said at the media conference that he thought the matter had been dealt with several years ago.

“I spoke to my wife and family at the time and am enormously grateful for their forgiveness and support," Paine said. "We thought this incident was behind us and that I could focus entirely on the team, as I have done for the last three or four years.

“However, I recently became aware that this private text exchange was going to become public.”

Paine said he didn't want the scandal to become “an unwelcome disruption to the team ahead of what is a huge Ashes series."

The series is one of the most anticipated in world cricket. After the opening test match in Brisbane, further matches are scheduled for Adelaide, Melbourne, Sydney and Perth. Australia holds the Ashes.

“I have loved my role as captain of the Australian cricket team," Paine said Friday. “I’m grateful for the support of my teammates and proud of what we’ve been able to achieve together. To them, I ask for their understanding and forgiveness. To Australian cricket fans I’m deeply sorry that my past behavior has impacted our game on the eve of the Ashes. “

Cricket Tasmania released a statement Friday saying the allegations against Paine were only raised when the female employee was charged with theft. Chairman Andrew Gaggin said no complaint was made until mid-2018 following the message exchanges in November 2017.

“As soon as Cricket Tasmania was made aware, it undertook an investigation that determined the interaction was consensual, private, occurred on the one occasion only, was between mature adults and was not repeated,” Gaggin said.

Paine has played 35 tests for Australia, taking 150 catches behind the stumps. He has scored 1,534 runs at an average of 32.63 with a high score of 92 and nine half-centuries.

Pat Cummins is now favored to become the first fast bowler to assume the full-time captaincy of the test team, although once sandpaper-tainted Steve Smith's name has also been mentioned.
