Postponed, as in let the Clenbutrol be out of his system. Not cancelled. September is a reasonable option.
Again, if Golovkin and his team felt they weren't safe in any way, they won't go on with the fight. Golovkin isn't desperate here, he can still make a lot of money fighting others and doesn't necessarily need Alvarez. Golovkin fans will make a big deal out of this till the fight is over to ensure saving face if Golovkin gets sparked. Hilarious.
Neither. Canelo should get off the juice and go back down to 147. Let the real, clean middleweights, GGG and Saunders settle, the MW supremacy.
