Jamie Foster is still at Huddersfield isn't he? He's another one.
Carl Forster at Salford and Chris Dean at Widnes from 1st team Super League squads who've been forgotten. In the Championship there's Gaskell, Paul Clough, Ian Hardman, Jacob Emmitt, Andrew Dixon, Tom Armstrong, Danny Langtree, Jordan Hand, David Hewitt and Matty Fozard.
Then if you consider players who were in our youth teams but have since been released still in Super League, you could add;
Matty Whitley - now at Widnes but played at both Warrington and Saints on scholarship.
Josh Wood - now at Salford but was at Saints on scholarship.
Joe Ryan - was at Saints until he was too old for u19s, now at Warrington playing reserve rugby.
