James Pattinson will miss Australia's first Test against Pakistan at the Gabba due to a suspension handed down by Cricket Australia (CA), it was announced on Sunday.
Australia and Victoria bowler Pattinson is ineligible for the series opener in Brisbane after being found guilty of a level two breach of CA's code of conduct for abuse of an opposition player in the Sheffield Shield.
The incident stems from Victoria's clash with Queensland in Melbourne and as it is Pattinson's third breach in the past 18 months, it triggered two suspension points and a subsequent one-match ban.
"I made a mistake in the heat of the moment," said Pattinson, who opted against contesting the charge. "Straight away I realised I was in the wrong, and I apologised immediately, both to the opponent and to the umpires.
"I have done the wrong thing and accept the penalty. I'm gutted to miss a Test match, but the standards are there for a reason and the fault is mine."
No replacement will be called into the Test squad for the Pakistan opener, which gets underway on Thursday.
"We have a duty to uphold the highest standards of behaviour and the action taken in this matter demonstrates that," CA's head of integrity and security Sean Carroll said. "On this occasion, James acknowledges he fell short of that expectation."
Australia captain Tim Paine told ABC Grandstand: "He knows that he's let himself down and let the group down. We hold ourselves to really high standards now with our behaviour ... so we're disappointed in that.
"James has owned up and he knows he's made a mistake. He's apologised for it and will come back bigger and better."
