State of Origin viewers left baffled by NSW wardrobe malfunction

State of Origin viewers couldn't help but notice an odd trend in Wednesday night's Queensland victory - the Blues seemed to be having some trouble with their shorts.

Queensland won a thrilling contest 16-10 thanks to some heroics from Cameron Munster and Daly Cherry-Evans.

Some fans amusingly pointed out that whoever makes the shorts for the Blues might need to produce some heroics of their own after they seemed to regularly slip down.

James Tedesco had the misfortune of having his entire rear bared to Sydney's Accor Stadium during one tackle.

It happened several other times throughout the match, leading to a number of comments remarking on it throughout the match on social media.

Some even accused Queensland of making it a tactic to pull the shorts down in each tackle, slightly delaying play as players fixed themselves up.

Only one side this century - Queensland 2017 - have lost the first game with home-ground advantage and gone on to claim the series.

The Blues have achieved the feat only once and not since 1994, after losing Origin I at the SCG before snatching the series with bounce-back victories at the MCG and Suncorp Stadium.

Twenty-eight years on, the Blues will need to prevail at Perth's Optus Stadium and Brisbane again to salvage the series from 1-0 down.

NSW coach Brad Fittler, who was a part of that 1994 side, said his side needed to give everything they had to bounce back.

"It's always tough. If you lose the first one, you're up against it," Fittler said.

"So we have to travel to Perth. We'll have a week's preparation there and obviously we've got to win it in Queensland.

"Winning a game there last year gave us a lot of confidence but it's a good challenge."

Queensland winger Xavier Coates limped off in the first half on Wednesday night, then interchange forward Jeremiah Nanai also suffered a leg injury after the break.

Even Fittler commended the Maroons for their fight against the odds.

"It was high tempo and helter skelter and they did really well after losing a winger," he said.

"They did well to keep the rhythm with what they were doing after that. They're some things that can knock you about."

NSW were awarded four set restarts for ruck infringements, but struggled to slow down a Queensland attack that played direct with Cameron Munster and Daly Cherry-Evans on the front foot.

Notably, Queensland's domination of the ruck came with the return of the likes of Cameron Smith and Billy Slater into the Maroons camp, with the play-the-ball an area they dominated during their decade of success.

Tedesco admitted he was unsure if Queensland had simply grown better in the tackle or if officials were not as stringent as in last year's lightening-paced series.

"It's hard to tell. There were no penalties," Tedesco said.

"They were probably holding us down for that extra second. It didn't allow us to free that space around the ruck and play with the freedom we wanted to."

Meanwhile Fittler also said he would await a response from the NRL on other crucial calls.

The Blues believed a forward-pass call that denied Tedesco a try that would have put the hosts 8-0 up was line ball, and claimed Kalyn Ponga's ball in the lead up to Dane Gagai's try moments later was also marginal.

Tedesco also questioned on field whether Daly Cherry-Evans' second-half try had come after Junior Paulo had been illegally held back in a scrum.
