Dylan Napa’s fitness will be assessed on Thursday after the Queensland prop tested his ankle injury at the Maroons’ Gold Coast camp.

Napa had been given until Wednesday to overcome the injury in order to play Sunday’s must-win State of Origin game two and took part in all but five minutes of Queensland’s first official training session.

While fullback Billy Slater (hamstring) declared himself a certain starter, Napa’s availability will hinge on how he pulls up on Thursday.
