Floyd said he'll announce his next fight on the 10th. A day before Thurman fights, so he's out of the running...
As soon as he gets clearance from the surgeon that his shoulder is 100% and the NSAC oks the cortisone injection pre-fight
When a 2 week period elapses of Khan not mentioning Floyd then assume Khan got the fight and Floyd will make the announcement shortly after that period. If Khan starts throwing feces at the wall then assume HOF'er Berto got the fight.
I thought I heard that somewhere, but sorry I'm mistaken. But he announced Maidana 2 on the 10th of July, and it shouldn't be much less than 2 months before the fight.
