Scotland coach Steve McCormack has included six uncapped players in a provisional 26-man squad for their autumn internationals.
The Scots play France in Perpignan on Saturday, October 27, before meeting Wales in a crucial World Cup qualifier in Glasgow on Sunday, November 4.
Wakefield utility player Kevin Henderson, Lee Patterson (Halifax), Graeme Horne (Hull), Dean Colton (Featherstone), James Morrow (Sheffield) and Richie Hawkyard (Swinton) are the new faces.
Henderson is poised to become the third Henderson brother to be capped by Scotland.
Hooker Andrew, the Castleford captain, returns to the squad after missing last season’s game against Wales, but Ian is unavailable after leaving Bradford to join up with his new club, New Zealand Warriors.
Horne, who played for England last season but also qualifies for Scotland, is set to follow in the footsteps of older brother Richard, the Hull half-back who represented Scotland in the 2000 World Cup.
McCormack will trim his squad to 20 after Sunday’s National League One Grand Final between Castleford and Widnes which will feature four of his players, while two more are expected to play for Featherstone in the League Two promotion decider against Oldham.
“Many of the squad are still playing or are having operations after their seasons but all 26 are in with a shout of making it,” McCormack said.
Former Gateshead utility back Wade Liddell is planning to return from Australia where he is playing with Easts Tigers.
Scotland provisional squad:
Alex Szostak (Bradford), Danny Brough, Andrew Henderson (both Castleford), Wade Liddell (Eastern Suburbs), Jamie Benn, Dean Colton (Featherstone), Lee Patterson (Halifax), Paul Jackson (Huddersfield), Graeme Horne (Hull), Gareth Morton, Jon Steel, Iain Morrison, Ben Fisher (all Hull KR), Dave McConnell, Mike Wainwright (Leigh), Iain Marsh (Rochdale), Jack Howieson, James Morrow (both Sheffield), Richie Hawkyard (Swinton), Kevin Henderson, Duncan MacGillivray (both Wakefield), Spencer Miller, Richard Fletcher (Whitehaven), Mick Nanyn, Oliver Wilkes (Widnes), Neil Lowe (York).
