Whatever the outcome, there's not much name recognition in Yarde and he isn't on the slide, so pretty unlikely. That said, I would be very surprised if Yarde pulled the upset here.
It's more about the belt for Canelo as I understand it. He wants to become LHW champion...and the obvious way to go is to fight Kovalev who's been on the slide. If Yarde looks like **** but still somehow manages to bear Kovalev, then Canelo could still fight him for that belt. He definitely not fighting any other LHW champs....although does Pascal have a belt now too? Maybe him.
