Collazo Gives Up a Belt, Sheeraz Chases Canelo: Boxing's Title Picture Reshuffles

LAS VEGAS

Monday is supposed to be boxing's quiet day. Nobody told the sanctioning bodies. By the time the WBO made its announcement on November 2, the sport's title picture had shifted in three divisions at once: a champion in the smallest weight class handed his belt back without a punch thrown, the super middleweight queue around Canelo Alvarez rearranged itself in public, and a Mexican champion in Riyadh used his post-fight moment to name the mandatory challenger most champions prefer to ignore. None of it happened in a ring. All of it matters for who fights whom in 2027.

Collazo walks away from the WBO belt

Oscar Collazo has formally relinquished the WBO minimumweight world title, the WBO announced on Monday, ending a reign that began in May 2023 when the Puerto Rican stopped Melvin Jerusalem in the seventh round to win the belt in just his seventh professional fight, according to BoxingScene. The timing tells the story: the WBO had ordered Collazo to defend against interim champion Ryusei Matsumoto, negotiations had failed to produce a deal, and a purse bid was scheduled for Monday at the WBO's headquarters in San Juan. Collazo's promoter, Miguel Cotto Promotions, notified the WBO of the decision before the bid could open, and the bid was called off, Boxing 24/7 reported.

Matsumoto, 9-0 with 4 knockouts, is elevated from interim to full WBO champion, subject to the WBO's official ruling, the organization said. The Japanese southpaw won the interim belt in Tokyo in late September, per BoxingScene. He gets the title, but he loses the thing every interim champion actually wants: the chance to take it off the real champion in the ring. BoxingScene reported that Japan's Teiken Promotions was prepared to bid $501,000 for the fight, money that almost certainly would have staged the bout in Japan. Collazo, clearly, had no intention of going.

Context makes the decision easier to understand, even if it stings. Collazo, 15-0 with 12 knockouts, still holds the WBA super title and The Ring belt at 105 pounds, so he does not wake up Tuesday beltless. And his autumn has been a mess: a rib injury suffered in training forced him out of an October 10 challenge in Chicago against unified flyweight champion Ricardo Sandoval — a two-division jump that showed exactly where Collazo's ambitions live, BoxingScene reported. Sandoval was then upset by replacement opponent Sergio Mendoza, which scrambled the flyweight picture Collazo was trying to enter. With a return targeted for early 2027 and his body growing out of the minimumweight division, defending a WBO belt at 105 against a mandatory in Japan was the one obligation that no longer fit the plan. For Matsumoto, BoxingScene notes his leading contenders include the Philippines' Vic Saludar and Jerusalem — the man Collazo beat for the belt — which means the division he now leads still runs through familiar names.

Sheeraz was in Riyadh for a reason

Hamzah Sheeraz did not fly to Riyadh on Saturday to watch boxing as a fan. The 27-year-old was ringside as Canelo Alvarez reclaimed the WBC super middleweight title from Christian Mbilli by unanimous decision — 115-112, 116-111 and 117-110 — and afterwards he made his intentions plain to The Ring's Mike Coppinger, according to Boxing News. "Why not test myself against the best?" Sheeraz said. "I'm in this game to be the best and to put myself in there with someone like the likes of Canelo. That's stuff you can only dream of."

Sheeraz, 24-0-1 with 19 knockouts, is in this position because of a belt he gave up. He vacated the WBO super middleweight title rather than defend it against mandatory challenger Janibek Alimkhanuly, a decision that drew heavy criticism at the time and looks different — not necessarily better, but different — if it lands him the biggest payday in the sport instead. The Ring rates Canelo No. 1 and Sheeraz No. 9 at super middleweight, per Boxing News, and Sheeraz reportedly believes the fight is close. Treat that last part as what it is: a fighter's optimism, not a signed contract. Nothing is booked.

What is known: Canelo, 36 and now 64-3-2 with 39 knockouts, named no opponent in Riyadh, said he would take a couple of weeks off, and has one fight remaining on his Riyadh Season deal, with March mentioned as a possible return window, British Boxing News reported. The queue behind Sheeraz is real — WBC interim champion Lester Martinez was also in Riyadh, and a Dmitry Bivol rematch and David Benavidez remain the prestige options — which is exactly why Sheeraz is campaigning now, loudly, while the seat is empty. Meanwhile the belt Sheeraz dropped has its own date: Alimkhanuly meets undefeated Dane Jacob Bank for the vacant WBO title on January 23 in Denmark, according to Big Fight Weekend, and Alimkhanuly has already publicly offered the Canelo–Mbilli winner a May unification, Boxing News reported. Win or lose the sweepstakes, the Kazakh is positioning himself as the division's unavoidable man.

Munguia calls out the man he's supposed to avoid

On the Riyadh undercard, Jaime Munguia did the opposite of the usual mandatory dance. The WBA super middleweight champion outpointed previously unbeaten Nikita Zon by unanimous decision, surviving a genuine scare in the sixth round to get there, according to Boxing News. Then, per reports from Riyadh, he called out Bektemir Melikuziev — the Uzbek who sits at No. 1 in the WBA rankings at 17-1 with 11 knockouts and holds mandatory challenger status. Champions are not supposed to volunteer for their mandatories on microphone. Munguia did it in the ring, minutes after his hardest round of the night.

That callout is a negotiation position as much as a challenge — Melikuziev's team can now hold him to it — and it is not a booked fight. But stack Monday's three stories together and a pattern emerges: Collazo shed the obligation that no longer served him, Sheeraz shed one to chase a bigger prize, and Munguia embraced his because his belt's credibility needs it. The belts are moving before the fights do. The first quarter of 2027 will tell us which of the three gambles was the smart one. Our full report on Canelo's win over Mbilli has the fight itself; this is the paperwork that decides what comes next.
