Shaun Marsh has been axed for the Sheffield Shield game against Victoria later this week but the Western Australian Cricket Association insist it was a decision based on form and not for his involvement in a boozy night at the Champions League in South Africa last week.
Marsh, who will return to club cricket, and his younger brother Mitch were dropped for the final Champions League group clash against Auckland last week after a late night celebrating Mitch's 21st birthday.
The WACA is still investigating matters in South Africa, with other players reportedly involved.
WACA chief executive Christina Matthews said there had been "no sanctions determined against Shaun" as yet.
"We haven’t had the opportunity to examine it. We will make decisions from there," she said.
"The players had a night out. I won’t go into specifics of the night out because it is unfair to the individuals involved."
WACA chairman David Williams said the timing of Marsh's dropping so soon after last week's incident was "a bit unfortunate".
But he added: "I don’t want the public to get the impression that this is a team running amok.
The challenge for us is to get the dressing room right and perform to the best of our abilities."
Western Australia coach Lachlan Stevens has thrown his support behind the brothers, declaring the WACA will support them through their latest misdemeanour.
But given their history of off-field indiscretions, the brothers face a sterner penalty than their teammates.
Mitch's antics have already cost him a spot in the Australia A side set to face South Africa in Sydney this week.
"If you've had the experience before, you've got to expect that you're going to be examined far more strongly than others," Matthews said last week after the behaviour of the Marsh brothers came to light.
WA face the Bushrangers in the Sheffield Shield at the MCG, starting on Friday, and in a one-day match next week.WA lost their opening two Shield matches of the season, and another defeat would put their campaign on the rocks.
