I'd be really surprised if Cano's chin is completely gone, though a Mexican warrior that's shot to bits at 28 isn't exactly a rarity. He took some good shots off a good puncher in his last fight before a perfect, on the button shot clipped him during an exchange and that was that. That Argentinian guy is a real power puncher though, the opposite of everything I've heard about Madiev.
IIRC as far as the undercard goes, there wasn't one that was aired. And nope, not yet, I don't binge watch anything, I drag stuff out, watch one a week maybe two at most, I like the anticipation and prolonging the pleasure, I'm up to Episode 5 of Season 1. As to why its taken so long since that post... I got distracted by the month long Giro D'Italia, Tour De France, and currently two weeks into the Vuelta A Espana, (No spoilers for today's stage please to the rest of you), and on top of that, I try to keep track of the new films coming out, or catch up on the ones I missed, I just got around to watching Infinity War yesterday.
