I think it's something else, if he got USADA'd, that's UFC business since they work together. That wouldn't be Dana's call to make it official but to say it's not their business, it can't be that, or Dana's purposely blurring the picture. Not money related because Dana said he didn't turn down Zabit. And he is not injured. Could be family related, like cancer or something.
But Dana wouldn't have reacted like that. When Whittaker took some months off for what we thought was family related, Dana had very kind words, that Robert was the most selfless guy he know or something.
My guess is it's something with the law. Not UFC related, not Dana related.. dude got jail time or something?
