SAINTS have named their 19-man squad for Sunday's Ladbrokes Challenge Cup quarter final with Widnes Vikings.

Matty Fleming and Lewis Charnock come in for Luke Thompson and the injured Shannon McDonnell.

In McDonnell's absence it seems likely that the full back duties will fall to Adam Swift, who has recovered from the neck injury he sustained at Castleford.

That would mean Fleming coming in on the wing. The other option is dropping Charnock back there.

Saints' 17 will come from: 3. Jordan Turner, 4. Josh Jones, 5. Adam Swift, 6. Travis Burns, 7. Luke Walsh, 8. Mose Masoe, 9. James Roby, 10. Kyle Amor, 12. Jon Wilkin, 13. Louie McCarthy-Scarsbrook, 14. Alex Walmsley, 15. Mark Flanagan, 17. Mark Percival, 19. Greg Richards, 21. Joe Greenwood, 22. Matty Dawson, 25. Andre Savelio, 26. Lewis Charnock, 30. Matty Fleming.

Widnes field a strong team, with Hep Cahill back on board after a lengthy shoulder injury absence.

Vikings: 1. Rhys Hanbury, 2. Paddy Flynn, 4. Stefan Marsh, 5. Patrick Ah Van, 6. Kevin Brown, 7. Joe Mellor, 10. Manase Manuokafoa, 11. Danny Galea, 13. Hep Cahill, 14. Chris Dean, 15. Jack Owens, 16. Willie Isa, 17. Chris Clarkson, 21. Danny Craven, 24. Macgraff Leuluai, 25. Alex Gerrard, 28. Matt Whitley, 33. Aaron Heremaia, 35. Gil Dudson. The game kicks off at 4pm and the referee is Robert Hicks.
