AS expected, Ben Barba is fit to return to the Saints side for Saturday's Challenge Cup tie at Castleford Tigers.

Barba missed last week’s win over Catalans after damaging shoulder/neck nerves against Salford.

Saints: 1. Jonny Lomax, 2. Tommy Makinson, 3. Ryan Morgan, 4. Mark Percival, 5. Adam Swift, 6. Theo Fages, 7. Matty Smith, 9. James Roby, 10. Kyle Amor, 11. Zeb Taia, 12. Jon Wilkin, 13. Louie McCarthy-Scarsbrook, 14. Luke Douglas, 15. Morgan Knowles, 16. Luke Thompson, 17. Dom Peyroux, 18. Danny Richardson, 19. Regan Grace, 23. Ben Barba.

Castleford are without influential seven Luke Gale, with former Saint Jamie Ellis taking his spot at scrum half.

Saints coach Justin Holbrook said: "Castleford will be a really good game and one we are looking forward to. 
"They will bring some players back in this week and are a strong opposition but we are OK with that.
"Luke Gale will be a big miss for them – he is their organiser there. But it won’t change the way we play. 
"He played round one against us. 
"They will bring Ben Roberts back in and they have Jamie Ellis there. "They still have some good halves but they will miss Gale."

Castleford: 2. Greg Minikin, 3. Jake Webster, 4. Michael Shenton, 6. Jamie Ellis, 8. Junior Moors, 9. Paul McShane, 10. Grant Millington, 11. Oliver Holmes, 12. Mike McMeeken, 13. Adam Milner, 14. Nathan Massey, 15. Jesse Sene-Lefao, 16. Joe Wardle, 17. Alex Foster, 18. Matt Cook, 19. Gladwin Springer, 21. Jake Trueman, 24. Jy Hitchcox, 32. Liam Watts.

Kick off is 2.30pm with the referee will be James Child.
