A Wembley appearance will cap a fairytale for Liam Finn, who joined Castleford Tigers from Featherstone Rovers in the off-season.
Finn was out of Super League for a decade, following spells with Wakefield and Halifax and he said: “Nine months ago I was a Championship player and now I’m getting ready to play at Wembley.
“It is a special place to train, never mind play. I am trying to keep a lid on it, but it would be fantastic if we could win.
“It is massive, beyond explanation. If you are in the game you hope experiences like this will come along.
“I owe it to [coach] Daryl Powell. I don’t think I’d be playing Super League if it wasn’t for a coach that understands my game and I’ve worked with before.
“I nearly ended up back at Halifax but I couldn’t turn this chance down and I’m glad I didn’t.”
