Mares didn't look all the great considering who he was fighting.
So it seems like they're trying to remove the sanctioning bodies from it as well. The announcer didn't mention Thurman's WBA belt, even though it's a nonsense title since Floyd is the WBA welterweight champion, and when they held the belt up after the fight someone from staff grabbed it, pulled it down, and said something to his cornerman that I'm guessing was about holding the belt up.
