At 12:40am ET, my UFC Fight Of The Week is on Jhonata Diniz. Derrick Lewis has been a fan favorite for a long time. The Black Beast has lost 4 of his last 6 fights though and he's now 39 years old. He's taking on a fighter who is 33 years old and has an undefeated record. This could be the end of the road for Lewis. Seven of Jhonata Diniz's 8 wins have been by KO/TKO, the other by unanimous decision. Diniz was thrilled to get Lewis as an opponent: “Derrick Lewis is a very big name not just in the UFC, but around the world when you talk about MMA. II really get surprised because he was booked to fight against another fighter. When the UFC came to us and let us know we were the new fighter for Derrick Lewis, it was a big surprise, big surprise, but we’re ready for him. I know how important is this fight for me and I know when I knock him out it will put me in another level in this organization. It really represents a lot to me." Lewis still has a lot of power but he's reckless, like a bar room brawler. Diniz, a former kickboxer, is much more precise. That edge in precision will provide him the advantage he needs and he will KO Lewis on Saturday.
