Not sure if you trust Wikipedia, but they have this posted on Floyd's main Wiki entry:

Here is the main entry for the non-fight between the two:

Interesting stuff. Floyd hasn't been genuine in all of this, and Manny and Arum should have never intimated that they won't draw blood so close to the event.

This certainly put Floyd and his team on their bike.

But, since Floyd has his own promotional company, it could be that the biggest fight in boxing history to happen, Floyd may just want all of that money between him, Schaefer and Haymon leaving out Oscar- who has been paying Floyd for so long.

Floyd is just looking out for his pockets if this is the angle. A douche and untrustworthy move, but self interest and preservation comes first.

This is why Oscar is back to doing business with Arum. Shaefer, Haymon and Floyd did a number on Oscar. Used his name, his money, his connections, and basically cut him out of a deal he spent a lot of time on.
