Just heard about this 10 mins ago. It's from Mark Geyer from triple m in Sydney. Those guys hear a lot of rumours which never come true so I'm not concerned. Rumour is he's signed for this year and will leave mid season which doesn't make too much sense to me.
The only possible reason to release him mid-season would be salary cap pressure... but I don't imagine he is on a motza now and he would need to be replaced at the very least, with someone subject to match payments..
