Castleford full-back Ryan McGoldrick and Wigan centre Karl Pryce are the stand-out names in the United States and Jamaica squads announced on Thursday for the 2013 World Cup qualifying matches.
McGoldrick is one of eight survivors from the Tomahawks team that lost to Samoa at Widnes in 2007 in the qualifying semi-final for the last World Cup.
Also in the 30-man squad is winger Matt Petersen, who played 16 matches for Wakefield from 2008-09.
The Americans, who are trying to qualify for their first World Cup under former Bradford coach Matthew Elliott, will be captained by Jacksonville's Apple Pope who led them in their recent Colonial Cup clashes with Canada.
"I know the players are keen to do well and I am very excited about the tournament and the challenges we will face," said Elliott, who will have former Leeds and Sheffield loose forward Marcus Vassilakopoulos as an assistant.
Pryce, the younger brother of St Helens and England stand-off Leon who spent the 2011 season on loan with Harlequins, is one of 18 players in Jamaica's 30-strong squad from either Super League or the Championship.
The others are Wayne Allen, Daley Williams (Batley), Joseph Brown (Gateshead), Jode Sheriffe, Paul White (Halifax), Lamont Bryan, Omari Caro (Harlequins), Ross Peltier (Huddersfield), Richie Barnett, Waine Pryce (Hunslet), Jymel Coleman, Jamaine Wray (Keighley), Danny Bravo, Jamal Chisholm (Leeds), Corey Hanson, Reece Williams, Sam Williamson (Sheffield Eagles).
"The squad has a good balance of experience and youth," said Jamaica coach Dean Thomas.
The Tomahawks and Jamaica will play a round-robin tournament also featuring South Africa in Philadelphia to determine the third member of group D alongside Wales and Cook Islands.
The South African squad is drawn exclusively from their domestic competition, with Tuks Bulls from Northern Gauteng having the most representatives.
"Although we have a relatively inexperienced team in terms of international games, we do have a very good mix of brawn and intelligence," said coach Steven van Zyl.
