Queensland winger Dane Gagai admits he will need to monitor a quad injury for the rest of the NRL season despite being cleared to play Wednesday’s State of Origin III in Sydney.

Gagai and veteran prop Nate Myles (knee) were on Sunday officially cleared for game three after completing Maroons training at their Gold Coast camp.

“Today was the test, the leg was good, I am right to go,” Gagai said.

“I still have three days to game day.

“These physios know what they are doing.

“I will do my best to be 100 per cent on Wednesday night.”

But Gagai expected his quad complaint – which also restricted his game two preparation – would linger for the rest of the year.

“Hopefully after this game I can monitor it a bit better,” the Newcastle flyer said.

“I feel confident running on it.”

Myles is a confirmed starter in Queensland’s front row after missing game two due to the injury.

Queensland coach Kevin Walters said he would not hesitate thrusting the 30-Origin veteran into the starting front row as the Maroons look to seal a fifth series whitewash.

Queensland have already clinched their 10th series win in 11 years.

“On Wednesday night we know it is going to be a forward dominated game and Nate is one of those players who enjoys playing in that arena,” Walters said.

“He has had a couple of weeks out and he assures us he will be fine.”

Walters was confident Gagai would shine in game three just as he did in Origin II after a similar injury plagued lead-up.

Despite missing a week of training, Gagai became just the fourth Maroon to bag an Origin hat-trick in their series clinching 26-16 game two win in Brisbane.

Queensland will leave for Sydney on Monday afternoon.
