So both Bivol and Zurdo looked vulnerable as of late, Bivol against Richards and while he won wide on the cards also got hit a little too much by lumbering Salamov. Zurdo struggled a lot more with a shot Gonzalez than most of us previously thought. Honestly Idk anymore who wins that but it's an interesting fight. Both Bivol and Zurdo will face a style they haven't faced so far, should depend on who can force the fight in a distance favoring them. If Bivol can keep Zurdo on the outside he probably wins, if Zurdo can cut distance and outwork Bivol then he wins.
I'd still take Beterbiev vs Bivol anytime over Bivol vs Zurdo though
Beterbiev stops both though. I don't see Bivol keeping Beterbiev away for long and when Beterbiev gets on the inside it's a wrap, Bivol can't fight on the inside and is not physically strong enough to deny Beterbiev in the clinch. Zurdo on the other hand likes to work on the inside/pocket but that will be to his detriment against Beterbiev.
