Munguia's WBA Title Defense in Doubt as Sanctioning Body Balks
The WBA says it never approved Jaime Munguia vs Nikita Zon, leaving the 46-2 champ facing a brutal choice five months into his reign.

Jaime Munguia's co-main-event slot on the Canelo-Mbilli card in Riyadh is hanging by a thread. A day after the promotion confirmed the lineup, the WBA shot back with a blunt statement: it never approved Munguia defending his super-middleweight belt against Nikita Zon. The sanctioning body says Bektemir Melikuziev is the official contender and that it'll review the matter.
That leaves the 46-2 (35 KO) champion in a nasty spot. Munguia has held the WBA strap for just five months, and the body is effectively telling him to honour his mandatory or step aside. If the WBA refuses to sanction the Zon fight — which looks like the way this is heading — Munguia either drops off the card or vacates a title he only just won.
Why Melikuziev Won't Budge
Reports suggest Melikuziev turned down a stepaside deal from Team Munguia, and the Uzbek made his position public on Instagram earlier this week. He argued he was the mandatory before Munguia even fought for the belt, and called for a real fight with real competition rather than one with a predictable outcome. Blunt, but hard to argue with when you're the man being skipped.
The card itself is stacked under the 'Mexico vs The World' banner, which makes the Munguia mess stand out more. Rafael Espinoza, unbeaten at 28-0 (24 KO) and coming off an 11th-round stoppage of Arnold Khegai, puts his WBO featherweight title on the line against Lorenzo Parra. There's also a vacant IBF super-lightweight scrap between Lindolfo Delgado — 24-0 (16 KO) and ranked #9 — and Artur Biyarslanov.
The Bigger Headache
At the top sits Canelo, chasing redemption after the third loss of his career against new WBC super-middleweight champ Christian Mbilli. That's the kind of main event that usually swallows every undercard storyline whole. Instead, the WBA's intervention has stolen a chunk of the spotlight.
And even the sanctioning squabble isn't the biggest question mark. There are concerns the entire event could be relocated given the escalating Houthi-Saudi conflict and its impact on Riyadh. A disputed title defense is one problem. A card with no venue is another entirely.
