Jake Emmitt has been told he will not play against until December due to a knee inury and is out of Wales' Four Nations squad.
The Castleford forward suffered the injury at Wigan in July and faces a lengthy recovery process.
"It's a real shame," Emmitt said. "I've been hoping that I'd recover in time to give myself a chance of playing in the Four Nations. It would have been a dream to face the Kiwis at Wembley and to play for Wales again.
"But it is not to be for me this year. I won't be able to do full training until December so now all of my focus is on getting back to my best for Cas at the start of next season."
