The NRL have confirmed Sydney Roosters coach Trent Robinson won’t be punished following his critcism of referee Ben Cummins on Friday.

NRL head of football Todd Greenberg says Sydney Roosters coach Trent Robinson won’t be sanctioned following his criticism of referee Ben Cummins after his side’s 8-0 loss to Manly on Friday.

Robinson labelled the performance of Cummins as “unacceptable” with the premiers on the wrong side of the penalty count for the third time in four games this season.

Manly won the count 11-2 and Robinson went on the front foot after the game accusing Cummins of coaching the Sea Eagles on the field instead of penalising them and allowing their players to milk penalties by staying on the ground.

However, Greenberg said he saw no problem with the comments and wouldn’t issue a $10,000 fine like he did to Manly coach Geoff Toovey following his infamous rant after a loss to South Sydney at Gosford last season.

“He didn’t question the referees’ integrity and it wasn’t excessive criticism,” Greenberg told AAP.

“He’s entitled to provide his opinion on their performance.”

Robinson’s measured, but scathing critique of Cummins came two weeks after he questioned the referee’s decision to not send off Parramatta’s Darcy Lussick for a high shot to the head of Jared Waerea-Hargreaves.

“You can’t have a game 11-2 against us and have those infractions in the game,” he said.

“They need to give a good explanation as to why that was the case. They (the referees) worked against each other.

“I’m happy with different rulings, but I can’t answer why we aren’t receiving penalties.”

The Roosters were the most penalised team in the NRL last season and this season were on the wrong side of the count 12-6 against Souths in round one and 10-3 in the win over Brisbane last week.

Robinson believes one reasons officials penalise his side so much could be because he orders his players not to play for penalties.

“We don’t lie down, we don’t play for penalties,” Robinson said.

“We might be wrong, but that’s our ethic. We don’t play for penalties.

“We openly talk about it. We are not going to lie down. We are going to stand up and keep fighting. We will let the footy gods decide. It’s not in the spirit of the game.”

Toovey, for once, was predictably less scathing about the officials, and even added the Roosters were fortunate to get away with just 11 penalties.

“I thought it could have been a lot more,” he said.
