Quote Him="Him"If he's a free agent then Salford have no authority over him whatsoever. If Salford want to decide who Hock can and can't play against then they need to retain him as a Salford player. They can loan him to Leigh, or anyone else, if they wish and put whatever restrictions they want on who he plays against.
But if Hock is not a Salford player then Hock should be free to play in any game Leigh wish to play him in.
Otherwise you'll eventually have the ridiculous situation whereby half the league can't play against each other.'"
I expect he is free to play Salford under the rules of the game, I also expect he'll be liable to repay whatever severance payments he's received for it though. The clause only runs as lon as he's receiving his severance - the term of his original contract. If another club had paid Salford for him, perhaps this would have been negotiated around.
The fact that he was granted his requested release and not retained until Salford could sell him on is why it is on Hock and not his new club. Surely these details would have been discussed in any negotiations with his new club as both Gareth and his agent were aware of the stipulation. If they weren't mentioned when Hock signed with Leigh that is neither Salford's fault or concern, they surely weren't involved with those negotiations at all.
TLDR; If Leigh had been willing to pay for Hock, they could have negotiated around the clause. They were after him pre-season but weren't willing to pay a fee.
