Did Floyd have a falling out with Roger Mayweather ?

I'm hearing his dad is the new head trainer because Roger is supposedly ill.. But I've seen interviews and him training other fighters and he looks like his normal self.. A while back I heard Roger had a meeting with Arum or something. Could that be the reason Floyd dropped him? I mean him going back to his dad seems drastic don't you guys think? For YEARS he talked bad about his dad and how roger made him and not his dad, never giving his dad credit.. NOW, with that being said is he trying to take a jab Roger? The same way he did with 50 cent, when he had the 50 falling out he started big upping 50s enemies like Rick Ross... OR roger is really sick and can't physically do it anymore as Floyd is a workout warrior. But I'm not buying that, that's a 200k payday. Roger won't be making that kind of money anytime soon
