UFC Record Breakdown
This one's got a weird vibe to it. Johnny Walker, the wild Brazilian who used to do backflips after knockouts at light heavyweight, is jumping up to heavyweight to face Ante Delija in Belgrade. Walker's coming off a split decision loss to Dominick Reyes back in April, but before that he starched Zhang Mingyang with ground and pound in the second round last August when he headlined in Shanghai. Delija, the former PFL champ ranked number 12, is trying to find his footing in the UFC after a rough stretch. He got finished by Waldo Cortes Acosta in under four minutes last November, then dropped a decision to Serghei Spivac in February.
If Walker's going to make a statement at heavyweight, it happens early before Delija's power finds him.
Here's the thing though. Delija did knock out Marcin Tybura in just over two minutes back in September 2025, so the power is real. But Walker's the kind of guy who makes every fight feel like it could end at any second. He's always been that chaotic energy fighter, throwing wild spinning stuff and hunting finishes. The question is whether that style translates when he's facing actual heavyweights who can crack back even harder.
Walker's fought at 205 his whole UFC career, dealing with guys like Ankalaev and Oezdemir who put him away. Now he's stepping into the heavyweight waters where one shot changes everything. Delija trains at Cro Cop Top Team, so you know he's got that Croatian heavyweight pedigree. This feels like a crossroads scrap for both guys. Walker needs to prove he belongs at heavyweight, and Delija needs to show he can hang in the UFC after dropping two of his last three.
