Joel will play alongside his brother Michael, and become the third set of brothers to play in a Challenge Cup final in four consecutive years.
Now Joel is looking forward to playing in his first club final alongside his brother.
He said: “To play alongside my brother will be a special moment for me, so I’m just looking forward to the weekend.
“I think it’s a very proud moment and my old man is as proud as anyone, he flew out Monday morning with his brother just to see his two boys run out at Wembley.
“My family have come over for Michael’s last two finals, and my Dad loves it. You couldn’t meet a bigger footy head so he couldn’t be happier and hopefully we can do well and send him home a winner.”
