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 as a disappointment to fans who were looking forward to a June 6 showdown in Sheffield, the boxer’s hometown, which would have been Smith’s first opportunity to protect the belt he captured from Subriel Matias in January.
Smith’s victory over Matias, a hard‑hitting Puerto Rican prospect, was a spectacular fifth‑round knockout that not only secured the world title but also elevated Smith’s professional record to an unbeaten 19‑0. The decisive moment came when Smith landed a powerful right hook that sent Matias to the canvas, followed by a second right hand that cemented the stoppage as the referee intervened.
Prior to the knockout, Smith had already begun to dominate the round with crisp jabs and effective movement, showing why he is regarded as one of Britain’s most promising talents in the division. The injury, which occurred during a routine training session, has left Smith’s camp with little choice but to pull the fight from the card. While the exact nature of the injury has not been disclosed, the decision underscores the physical toll that elite boxing can exact on even the most conditioned athletes.
Smith’s withdrawal reshapes the evening’s lineup at the Utilita Arena. Instead of the anticipated headline clash with Puello, the main event will now feature Galal Yafai, the British flyweight champion, who will contest a unification bout against WBA title‑holder Ricardo Sandoval.
Yafai’s fight, which also carries WBC and WBA world flyweight belts, promises to deliver the excitement that fans were expecting from the original headliner. Smith’s absence does not diminish his recent achievements.
By winning the super‑lightweight championship, he joined a distinguished group of British fighters who currently hold world titles, including heavyweight Fabio Wardley, welterweight Lewis Crocker, super‑featherweight Jazza Dickens, and featherweight Nick Ball. This cohort of champions highlights the depth of talent emerging from the United Kingdom across multiple weight classes. The background to Smith’s title win is worth revisiting.
In January, he travelled to Brooklyn, New York, to face Matias, who was riding a wave of momentum after a series of impressive performances. Matias entered the fight with a reputation for aggressive combinations and a solid record, but Smith’s disciplined game plan and superior hand speed allowed him to weather the early storm of uppercuts and body shots. By the fifth round, Smith’s confidence was evident as he began to dictate the pace, culminating in the knockout that not only ended Matias’ career‑defining night but also marked the first time the Puerto Rican fighter had been stopped inside the distance.
Matias’ record fell to 23‑3, while Smith’s tally rose to 19‑0, reinforcing his status as an unbeaten champion. There was also a brief controversy surrounding Matias prior to the fight. In November, Matias tested positive for a prohibited substance, sparking speculation that his upcoming bout could be jeopardized. However, a review a month later cleared him of any wrongdoing, allowing the fight to proceed as scheduled.
This episode added an extra layer of intrigue to the matchup, but ultimately it was Smith’s skill that prevailed. Looking ahead, Smith’s camp will likely aim to reschedule the defense against Puello once the boxer has fully recovered.
Puello, a formidable opponent with a solid record in the super‑lightweight division, remains a high‑profile challenger, and a future encounter could generate significant interest both in the UK and internationally. In the meantime, British boxing fans can turn their attention to Yafai’s unification bout, which promises to showcase the technical brilliance and speed typical of the flyweight class. For those who follow the sport closely, the broader boxing calendar for 2026 continues to fill with marquee events. Promoters are already outlining tentative dates for major fights across all weight divisions, ensuring that the sport remains in the spotlight throughout the year.

In summary, Dalton Smith’s injury has forced him out of his scheduled title defense against Alberto Puello, shifting the main event at Sheffield’s Utilita Arena to a flyweight unification bout featuring Galal Yafai and Ricardo Sandoval.
Despite this setback, Smith’s recent triumph over Subriel Matias remains a career‑defining moment, cementing his place among Britain’s current world champions and setting the stage for a future showdown once he is back to full health.
