Dalton Smith will not be able to defend his WBC super-lightweight crown against Alberto Puello after suffering an injury during his training camp, officials confirmed. The bout, which had been slated to headline a June 6 event in Smith's native Sheffield, was to be the champion's first title defense since he captured the belt from Subriel Matias in January. That victory, achieved with a decisive fifth‑round knockout in Brooklyn, propelled Smith to an unblemished 19‑0 record and placed him alongside fellow British world champions Fabio Wardley (heavyweight), Lewis Crocker (welterweight), Jazza Dickens (super‑featherweight) and Nick Ball (featherweight).
The sudden cancellation of Smith's fight has forced promoters to reshuffle the card, and the main attraction will now be Galal Yafai's attempt to unify the WBC and WBA flyweight titles against Ricardo Sandoval at the Utilita Arena. Yafai, another rising British star, will inherit the spotlight that Smith was expected to command. Smith's triumph over Matias was a showcase of power and precision. In the fifth round, a perfectly timed right hook sent the Puerto Rican challenger to the canvas, and the referee halted the contest even as Matias tried to rise.
Earlier in that same round, Smith had already landed a crisp right hand that unsettled Matias, setting the stage for the final blow. The win not only added a world title to Smith's resume but also marked the first time Matias had been stopped, dropping his professional record to 23‑3. The injury that forced Smith out of the Sheffield showdown was reported to be a muscle strain sustained during a routine sparring session. While the exact nature of the problem has not been disclosed, Smith's camp indicated that he will undergo a period of rest and rehabilitation before returning to the ring.
The decision to pull the fighter from the card was made out of an abundance of caution, ensuring that the champion does not risk aggravating the issue and jeopardize his long‑term health. The cancellation has broader implications for the 2026 boxing calendar.
Fans who were looking forward to a high‑stakes clash between two undefeated prospects will now have to wait for a rescheduled date, likely later in the year, when Smith has fully recovered. In the meantime, the promoter is expected to seek a replacement opponent for Puello, or possibly move the fight to a different venue and date, to keep the momentum of the super‑lightweight division alive. Beyond the immediate fallout, Smith's career trajectory remains promising.
At 28, he has already amassed a perfect record and demonstrated the ability to finish fights decisively. His aggressive style, anchored by a powerful right hand, has drawn comparisons to some of the modern greats in the weight class.
Moreover, his willingness to fight on foreign soil, as evidenced by his successful debut in the United States, underscores his ambition to become a global name in boxing. The episode also highlights the rigorous demands placed on elite athletes. Training camps are intense, with fighters often pushing their bodies to the limit in pursuit of peak performance. Injuries, while unfortunate, are an inherent risk in a sport that relies on explosive power and relentless conditioning.
Smith's team has emphasized that his health will always come first, and that a full recovery is essential before he steps back into the ring. For supporters of British boxing, the news is a disappointment, but there is optimism that Smith will return stronger.
The British boxing community has rallied around the champion, with fellow title‑holders and fans sending messages of encouragement on social media platforms. The upcoming unification bout featuring Galal Yafai will now serve as the marquee event for British fans on the night originally earmarked for Smith, offering a glimpse of the depth of talent present in the UK across multiple weight divisions. In related news, Smith's previous fight against Matias was briefly clouded by controversy when Matias tested positive for a prohibited substance in November.
After a thorough investigation, the anti‑doping authorities concluded that the 33‑year‑old boxer was not at fault, clearing him of any violation. This episode added an extra layer of drama to the matchup, but ultimately the focus remained on Smith's performance and his ascent to world champion status. Looking ahead, the boxing world will be watching closely for updates on Smith's recovery timeline.
Once cleared, the champion is expected to resume his campaign, possibly targeting another top‑ranked contender in the super‑lightweight division. Until then, fans can stay engaged with the sport through various platforms, including the NOW streaming service, the weekly Toe2Toe podcast, and the extensive highlights library that captures the most exciting moments from recent bouts.
