SHARKS captain Paul Gallen has told the Cowboys to "suck it up" and says the seventh-tackle try debacle is no more a conspiracy than Queensland's golden Origin run.

On the same day North Queensland CEO Peter Jourdain backed down from claims of a Sydney bias, Gallen urged the team he helped eliminate from the NRL finals to get over the Beau Ryan try scored on the seventh tackle.

The NSW skipper, whose side will meet Manly on Friday night, said the Cowboys were doing themselves no favours by pleading for justice, four days after the 20-18 loss at Allianz Stadium.

"I think they are (carrying on) now," he told Sky Sports Radio.

"It's a mistake and we don't want to see it happen. I'd probably be a bit upset too.

"But to say it's cost them a game and (with claims of) conspiracy theories, no one stopped on the field. No one knew it was seventh tackle.

"The seventh tackle didn't make Sam Tagataese run over the top of four blokes. I think while it's a mistake we've got to get on with it."

Though a noted critic of officialdom in the past, Gallen said the Cowboys went too far by questioning the referees' impartiality.

"I was upset last year during the Origin series, but I'm not saying it's a conspiracy theory and it cost us the game," he said.

"That's like me coming out and saying it's a conspiracy that Queensland has won Origin the past eight years when you look at (the) Greg Inglis or Justin Hodges tries last year.

"(The Cowboys) had plenty of opportunities to win. To say it cost them the game, I think they're using that as an excuse."

North Queensland supremo Jourdain this morning admitted his club may have been blinded by rage immediately after the sudden-death finals match.

"Straight after the game, there were a lot of emotions," he said.

While not ruling it out, Jourdain conceded a play for financial compensation from the NRL was likely to be fruitless.
