Wales coach John Kear has included three players involved in the Super League play-offs in a 23-man squad for the Nines World Cup in Sydney on October 18-19.
St Helens winger Regan Grace, Wigan prop Ben Flower and Salford front-rower Gil Dudson are among those chosen to take part in a training camp in North Wales in late September after which Kear will name his final 16-man squad.
However, the Grand Final takes place just a week before the tournament and the availability of all three players could hinge on the success of their clubs in the play-offs.
All but three of the 23 have been picked from Wales' elite train-on squad announced for 2019 and 2020, with Burleigh Bears' Will Evans, Huddersfield academy player Josh Pinder and Daniel Brown of St Mary's drafted in.
Kear said: "We've got plenty of quality in our squad and we're looking forward to giving it a good go.
"This format is going to be new to a lot of the players but it's an opportunity for them to go out to Australia, enjoy themselves and build on last year's internationals.
"We've got a lot of young players coming through and it's a chance for them to test themselves against some of the best players in the world.
"It'll be good to have a couple of players returning to the frame this year and they're all keen to be on board as we build towards the next European Championship and World Cup."
