Dalton Smith will not be able to defend his WBC super‑lightweight crown against challenger Alberto Puello after sustaining an injury while training. The bout, which had been slated to close out a June 6 card in Smith's native Sheffield, was to be the champion's first defense since he captured the belt from Subriel Matias in January. However, the setback forces promoters to reshuffle the evening’s lineup, promoting Galal Yafai’s unification clash with Ricardo Sandoval to the main event at the Utilita Arena. Smith, 28, entered the ring in Brooklyn in January with an unblemished 18‑0 record and a reputation for powerful right‑hand punches.
In the fifth round of that fight he delivered a decisive right hook that sent Matias crashing to the canvas. Although the Puerto Rican tried to rise, the referee stopped the contest, awarding Smith a knockout victory and his 19th professional win.
Earlier in the same round Smith had already landed a crisp right hand that further destabilized Matias, underscoring the British boxer’s aggressive style and finishing ability. The Sheffield showdown was meant to be a showcase of British boxing talent.
Alongside Smith, fellow countrymen Fabio Wardley (heavyweight), Lewis Crocker (welterweight), Jazza Dickens (super‑featherweight) and Nick Ball (featherweight) were all slated to appear on the same card, creating a rare gathering of current male world champions from the United Kingdom. With Smith’s bout now cancelled, the promoters have elevated Yafai’s WBC‑WBA flyweight unification fight against the Mexican contender Ricardo Sandoval to headline status, ensuring the event still offers a world‑title showdown for the local crowd.
Smith’s path to the title was not without drama. After his victory over Matias, the former champion faced a potential suspension when Matias tested positive for a prohibited substance in November.
The anti‑doping authorities initially threatened to overturn the result, but a subsequent review cleared Smith of any wrongdoing, confirming that the win stood and that Matias’ positive test did not implicate the British fighter. The decision allowed Smith to retain his newly won belt and continue his ascent in the division. The injury that forced Smith out of the June 6 fight was reported as occurring during a routine training session. While the exact nature of the ailment has not been disclosed, sources close to the camp indicated that it was serious enough to prevent him from traveling to Sheffield and stepping into the ring on short notice.
In the world of professional boxing, even a minor strain can jeopardize a fighter’s performance, especially when a world title is on the line, so the decision to withdraw was made in the interest of both the athlete’s health and the integrity of the contest. Smith’s record now stands at 19‑0, with 13 wins coming by way of knockout. His aggressive, pressure‑based approach, highlighted by that signature right hook, has made him a fan favorite and a rising star in the super‑lightweight division.
Analysts note that his next opponent, Alberto Puello, is a skilled and experienced contender who would have provided a stern test for the unbeaten Brit. Puello, known for his slick footwork and counter‑punching, would likely have forced Smith to adapt his usual forward‑pressing style, potentially leading to a compelling tactical battle.
The cancellation also impacts the broader boxing calendar for 2026. Fans and pundits alike have been eager to see how Smith’s career will develop, especially as he joins a select group of British fighters who hold world titles across multiple weight classes. His absence from the Sheffield card creates a ripple effect, prompting promoters to look for replacement fights or to reschedule the defense for a later date, possibly in a different venue. Meanwhile, the rest of the card proceeds as planned.
Galal Yafai, the British flyweight champion, will now headline the event, facing Ricardo Sandoval in a unification bout that promises to be a high‑octane affair. Yafai, who holds both the WBC and WBA titles, has been praised for his speed, accuracy, and ring IQ, while Sandoval brings power and relentless pressure. Their clash is expected to draw significant attention, both domestically and internationally, as it will determine the undisputed flyweight champion.
