Yep.
As for the OP, why would Manly take a player off our hands when he's out for the season with injury?
Stranger deals have happened in the NRL, with a retiring Lyon it wouldn't be too far fetched for Manly to attempt to get 2/3 guys fighting for that 5/8th spot if Walker was to move back to centre.
Manly signed Tim Moltzen after all his injuries, at what i priced for Luke Kelly i wouldnt be suprised if your club thinks its a steal lol.
