Fullback Kalyn Ponga is set to make his Queensland debut in Sunday's second State of Origin rugby league clash with New South Wales.

The 20-year-old Newcastle star was included yesterday in coach Kevin Walters' 18-man squad for the match and is expected to make his first Origin appearance off the bench.

Walters has named veteran fullback Billy Slater but is sweating on the 35-year-old's fitness as he battles a hamstring strain. Slater and Dylan Napa, who has an ankle injury, will be given until tomorrow to prove their fitness.

Ponga comes into the Queensland squad for the first time as a replacement for Anthony Milford as Walters contends with a number of injuries.


"He's been playing some good football for Newcastle Knights this year and knocking on the door. [He was] very close [for] game one and we expect to have him in game two," Walters said. "We've got some plans about how we want to use him, going to be a long-term player for us and grateful we've got him into the side this time around."

Queensland trail 1-0 after losing game one 22-12 to a young New South Wales team.
