England Academy have named a 43-man performance squad ahead of their tour to New Zealand and Australia in August/September.
The list includes four from Newcastle Thunder, a sign of the further development of the game in the north east.
Super League champions St Helens, Leeds and Wigan all supply six players apiece, with Warrington heading the list with seven players.
Championship sides Widnes (2) and Bradford (1) also have players selected.
Dave Elliott, the RFL’s National Programmes Manager, said: “The purpose of the England Academy Programme is to identify players who have the potential to play international Rugby League at senior level in the future and to create development opportunities for them here and now.
“We’re very excited about the prospect of a tour Down Under, but there’s a lot of hard work before then and nobody is certain of a place. We’ll be keeping a keen eye on club form, listening to club coaches and running regular training sessions throughout the year. And, as in 2019, this year’s ‘Origin’ fixtures will form a significant part of the preparation and selection process.”
Squad members will come together for the first time at Weetwood Hall in Leeds on Wednesday 19 February.
Academy Origin matches are scheduled for 13 May and 24 June at Batley and Wakefield respectively, with training sessions taking place at Weetwood throughout the spring and summer.
Selection for the four-week tour of New Zealand and Australia, which begins on 10 August, will take place at the end of June. Full tour details will be announced in due course.
