Barrera is facing Valera on the undercard of Kovalev vs Sharbranskyy. According to ESPN the fight is a done deal but I can't see it officialy added to boxrec.
I can't wait to see Valera flop and flail around the ring spoiling, holding and possibly fouling and be dropped 3 o 4 times on his way to a lopsided UD loss.
I don't know as Valera seems to be pretty good at surviving. Bivol hit him with everything but the kitchen sink, and he went the full 12 anyway. Barrera is more experienced as a green Bivol, but still.
