I read on boxingtalk that Arum was saying two days ago that the offer to Floyd was off the table and he was setting up a fight for Tony in december. Though it was against an "unnamed opponent" and i suppose he'd abandon that plan pretty quickly if floyd changed his mind.

I'm not sure spinks would be that easy a fight though. Zab wasn't an easy fight until the later rounds and I imagine spinks would go the same way--he's fast and slick just like Zab (though I guess with less power), and fades in the later rounds too.
