Des Hasler has received an ultimatum from the NRL after his pointed criticism towards bunker official Kasey Badger in the round 13 post-match press conference.
In a statement released by the league, the long-time head coach was issued a final warning for his behaviour.
"The NRL has issued Gold Coast Titans coach Des Hasler with a final warning for direct and targeted criticism of NRL match officials.," the statement read.
"Mr Hasler has been reminded of his obligations under the NRL Rules and Code of Conduct as well as his general responsibility as a sporting leader."
Despite being a reserved character as a player, the 64-year-old has become infamous for his blow-ups at referees since becoming a coach.
The Sporting News ranks Des Hasler's most infamous rants toward match officials.

Hasler had many memorable moments as Sea Eagles head coach, however one that has clearly stuck in the mind of NRL officials was his comments about referee Ben Cummins.
In his post-match press conference, he slammed the 9-2 penalty count in favour of the Eels.
"[The Eels were] legged back into the game,” said Hasler.
In what was a fairly tame comment by his standards, the issue compounded when he doubled down on his take during an interview with the Sydney Morning Herald later that week.
Hence, Manly got slapped with the fine and Des added yet another paragraph to his lengthy rap sheet.

Hasler was at his patronising best on this occasion, following a narrow victory over the Knights.
His main issue on that night was how the ten-metre rule was enforced; even going as far as to say that he would slap then head of football Todd Greenberg with a breach of his own.
"I think I might send Todd Greenberg a breach notice. In fact, I will," he said.
"I want to send them a breach notice for misrepresentation.
"You had a couple of times there where (the referee) could've done something about it but it was just out of his depth, the poor fella."
That sledge wasn't his first of the 2015 season, he already had $10,000 in fines that had been suspended from round one.

Better known as the infamous 'Voldemort' scandal, Hasler really outdid himself with his performance in the post-match press conference after the Bulldogs round one clash against the Panthers.
He became the first person to be sanctioned under the NRL's edict banning coach's from talking about referees.
It took Hasler one week to falter under the new crackdown, despite his best attempts to circumvent the rules by referring to those who shall not be named under a creative alias.
"Let's call him Voldemort," said Hasler.
""Paragraph 31, sub-clause two says that comment on means you can't say anything nice about them, you can't say anything positive about them, you can't say anything about the Voldemorts.
"So when it comes to the Voldemorts I'll just follow the policy."
