Queensland prop Dylan Napa has been cleared to play Sunday night's must-win State of Origin game two in Sydney.
Maroons assistant Josh Hannay said on Sunday morning the Sydney Roosters enforcer was still not 100 per cent fit but would nurse his injured ankle through a match Queensland must win to keep the series alive.
"It is hard to place a percentage on the injury but he has done everything asked of him this week – he is ready to go," Hannay said.
Queensland coach Kevin Walters had initially given Napa a deadline on Wednesday to prove his fitness.
Walters had been keen to avoid any more distractions after a nightmare build-up to the series opener in Melbourne where three players suffered injury scares and Billy Slater (hamstring) pulled out days before the game.
But Walters has retained Napa after he surprised the coach by showing promising signs at their Gold Coast camp, completing both their full training sessions without receiving an official green light to play.
"I didn't expect him to be running too much on Wednesday but he trained fully with the team, did exactly what was required," Walters said of Napa.
"He has worked around the clock, it is a clear indication how dedicated he is, he wants to be part of this game."
There had been speculation lock Josh McGuire would be elevated to the front row with bench forward Jai Arrow wearing the No.13 jersey if Napa was cut.
Walters admitted he may have to curb Napa's aggression if he does get onto the field.
"He brings first and foremost aggression. Dylan would be the first to admit that he didn't quite get that right in game one," Walters said.
"If we can get that right he will be a huge asset for the Maroons. That's why we are giving him every opportunity to play."
Walters said Queensland were pumped up to celebrate veteran fullback Billy Slater's 30th Origin game on Sunday night.
Appearing in his swansong Origin series, Slater, 35, becomes the 11th player and 10th Queenslander to reach the milestone.
