Rangi Chase trained with the Cas Tigers squad today.
We are missing a half back for the rest of the year in Ben Roberts. We have been playing our best forward (Millington) there instead.
Didn't your chairman claim to have held his registration? Would he be willing to let Rangi play at Cas for the rest of the year?

No problem, how much have you got?

We'll give you Michael Shenton till the end of the year.

We'll take Denny Solomona & a packet of pork scratchings in exchange.

You can borrow Denny for a week.
It would certainly be an interesting situation. Working in this area myself, nothing is ever black and white and is mostly confusing and murky.
Assuming Leigh cannot afford to pay Rangi to rejoin them as this would take you over the salary cap, it would seem unreasonable to restrict his employment by effectively saying "we don't want you, but nobody else can employ you either".

Doesn't he have to sign by midnight tonight to be able to play in the 8s

Yes but he did steal a living of us for about 4 months

Exactly what Huddersfield are doing with Kieron Purtill!

Not if they are paying him.

Well, his disillusionment with rugby league lasted a long time, didn't it? Also, what became of his opportunity to "pursue a career outside rugby league"?

He has realised he can't do anything else.

In fairness, Rangi's circumstances might suggest a move back to Cas would be sensible.
He has openly said things started to go wrong for him in his final season at Cas, with Salford courting him and endless rumours about his future.
He joined Salford but things didn't go well. His Castleford-based partner did not want to move and Rangi struggled to settle away from his family. He and his partner separated and he signed for Leigh in good faith thinking his relationship was over. However, he reconciled with his partner and therefore wanted to prioritise his family. As they still live in the Castleford area, it would make sense for him to give it another go at a local club where he has experienced success before.
