SOO MAROONS TRAINING
Melbourne's Tim Glasby is on standby for Dylan Napa after Queensland admitted the Sydney Roosters prop was their biggest injury concern ahead of Sunday's must win State of Origin game two in Sydney.
Napa and defensive specialist Glasby were on Monday named in an alphabetical 18-strong Maroons squad which featured one debutant - Newcastle young gun Kalyn Ponga.
But Maroons selectors boss Gene Miles said Glasby would only be injected into the 17 if Napa failed to overcome an ankle injury sustained in the Roosters' last-round NRL win over Penrith.
Napa and fullback Billy Slater must prove their fitness by the Maroons' first training session at their Gold Coast camp on Wednesday.
Queensland were confident Slater would overcome a hamstring complaint that forced him to miss their game-one loss in Melbourne, and play his 30th Origin.
But there were concerns for the fiery Napa who will line up in the front row with Gold Coast's Jarrod Wallace if cleared.
"Tim is on standby for Dylan. Dylan is our biggest concern but he is on a deadline," Miles said.
"Dylan says he wants every opportunity to play and we will go with that because he is an important part of the team - we need his aggression.
"We are very hopeful he will pass that test."
Glasby is on the verge of a recall after playing the last two games of 2017 series, proving the key to Queensland plugging their defensive holes following a record Origin I loss last year.
There are no concerns for Slater who pulled out just days before game one in Melbourne in a nightmare build-up for the Maroons.
He will still need to get an official medical clearance on Wednesday.
"Billy hasn't done it before so he doesn't really know how to treat a hamstring or when to test it so he must be feeling OK if he gave Kevvie the all clear," Miles said.
Ponga - just 20 - looks set to make his debut as a bench utility replacing Brisbane's Anthony Milford after Michael Morgan was ruled out for the season with a biceps injury last weekend.
"The game will dictate where Kalyn plays and how long. Let's hope we can get him into the game and he can show us what he has done the previous 12 months," Miles said.
Wallace received a reprieve after a quiet game one that featured just five carries.
Miles said Brisbane duo Joe Ofahengaue and Corey Oates plus North Queensland winger Kyle Feldt were unlucky not to be named in the squad.
In their first season without their Big Three, Queensland have their backs against the wall after their 22-12 game one loss to a new look NSW.
Beginning life without Cameron Smith, Johnathan Thurston and Cooper Cronk, the Maroons must win on Sunday to keep alive their stunning run of 11 series victories in 12 years.
