And it's time! UFC 255's live stream brings you a night full of flyweight action from Las Vegas. At the top of the card are two title fights, with No. 3 ranked Jennifer Maia taking on women's flyweight champion Valentina "Barrett" Shevchenko and No. 4 ranked Alex Perez taking on men's flyweight champion Davesson "Dyko" Figueiredo.

Interestingly, both champions are expected to retain by TKO. Shevchenko is the more dominant champion, and only Amanda Nunes had a chance to dethrone her, but still did not.

With only three losses, Shevchenko is surely the "bullet" that cuts through most obstacles. Some worry that she will fight at Maia's level instead of performing at her best.

Figueiredo may not be as fast as he was in his youth, but he will definitely beat his challengers. And he may endure. But... I wouldn't make that bet. [Here's what you need to know to watch UFC 255 live streaming online:
