Dalton Smith will not be able to defend his WBC super‑lightweight crown against Alberto Puello as a training‑camp injury has forced him out of the bout. The cancellation comes just weeks before the fight, which had been slated to take place on June 6 at the Utilita Arena in Smith’s hometown of Sheffield. The match would have been Smith’s first opportunity to protect the belt he captured in January when he stopped Subriel Matias with a fifth‑round knockout in Brooklyn.
Smith’s victory over Matias was a landmark moment for British boxing. By beating the Puerto Rican contender, the 28‑year‑old joined a select group of home‑grown world champions that now includes heavyweight Fabio Wardley, welterweight Lewis Crocker, super‑featherweight Jazza Dickens and featherweight Nick Ball. The win elevated his record to an unbeaten 19‑0 and cemented his status as one of the sport’s rising stars. The injury that has sidelined Smith was reported to have occurred during a routine sparring session in his preparation camp.
While the exact nature of the ailment has not been disclosed, his team confirmed that continuing to train for the June 6 showdown would jeopardise his health and potentially prolong his recovery. As a result, the promoters have pulled the fight from the card and are reshuffling the evening’s lineup. With the Smith‑Puello showdown removed, the main event for the Utilita Arena will now feature Galal Yafai, the British flyweight champion, in a unification clash against Ricardo Sandoval. Yafai holds both the WBC and WBA flyweight titles, and the bout promises to deliver the high‑stakes drama that fans were expecting from the original headline.
Smith’s absence is a disappointment not only for the local crowd, who were eager to see a hometown hero defend his title, but also for the broader boxing community that has been tracking his rapid ascent. The British fighter’s style—characterised by a powerful right hook, crisp footwork, and an aggressive approach—has drawn comparisons to some of the sport’s modern greats. In his fight with Matias, it was that very right hook that sent the challenger to the canvas, prompting the referee to stop the contest even as Matias attempted to rise. Earlier in the same round, Smith had already landed another decisive right hand that rocked Matias, setting the stage for the final blow.
The Matias bout was not without its own controversy. In November, Subriel Matias tested positive for a prohibited substance, casting a shadow over the result. However, after a thorough investigation, the anti‑doping authorities cleared the 33‑year‑old of any wrongdoing, determining that there had been no breach of the sport’s drug policy. The decision allowed the fight’s outcome to stand and preserved Smith’s unblemished record.
Beyond the immediate fallout, Smith’s injury raises questions about his future schedule and the timing of his next defense. Boxing analysts suggest that, once fully recovered, Smith could be back in the ring within three to four months, depending on the severity of the setback.
Potential opponents have already been floated, with names like Alberto Puello, who was originally set to challenge him, and other top‑ranked contenders in the 140‑pound division emerging as viable options. The British Boxing Board of Control (BBBofC) and Smith’s promotional team are expected to issue a formal statement in the coming days outlining the medical assessment and a tentative timeline for his return. In the meantime, fans can stay engaged with the sport through a variety of platforms. Sky Sports continues to provide live streaming of upcoming fights, while the NOW service offers a contract‑free way to watch boxing events online.

In summary, Dalton Smith’s forced withdrawal from his scheduled title defense is a setback for both the fighter and the Sheffield crowd that had eagerly anticipated the event. While the injury postpones his first defense of the WBC super‑lightweight belt, it also opens the door for other high‑profile matchups once he is cleared to compete again. The upcoming Yafai‑Sandoval unification fight will now headline the June 6 card, ensuring that the night still delivers world‑class boxing action.
