Dalton Smith will not be able to defend his WBC super‑lightweight crown against Alberto Puello after he suffered an injury while training. The bout, which had been slated to headline a June 6 event in Smith’s hometown of Sheffield, was intended to be the champion’s first defense since he captured the belt from Subriel Matias in January. The injury forced the promoters to scrap the matchup, leaving a gap in the card that was subsequently filled by Galal Yafai’s unification fight for the WBC and WBA flyweight titles against Ricardo Sandoval. Yafai’s contest will now serve as the main attraction at the Utilita Arena on the same night.

Smith’s victory over Matias was a landmark moment in British boxing. By stopping the Puerto Rican challenger in the fifth round with a powerful right hook, the 28‑year‑old Brit extended his unbeaten record to 19‑0 and joined a distinguished group of current male world champions from the United Kingdom, including heavyweight Fabio Wardley, welterweight Lewis Crocker, super‑featherweight Jazza Dickens and featherweight Nick Ball. The knockout came in Brooklyn, where Smith delivered a crisp right hand that sent Matias crashing to the canvas.

Even though Matias attempted to rise, the referee intervened and halted the contest, awarding Smith a decisive victory. Earlier in that same round, Smith had already landed a second right hand that stunned his opponent, setting the stage for the final blow. The loss of the Smith‑Puello fight is a disappointment for fans who were eager to see the champion defend his title on home soil. It also disrupts the broader schedule of high‑profile bouts that have been mapped out for 2026, a year that promises numerous marquee events across the sport.

The boxing calendar continues to evolve, with promoters scrambling to re‑arrange match‑ups and ensure that ticket buyers still receive a compelling show. In addition to the headline change, the card will still feature a variety of supporting fights and entertainment options. Viewers can look forward to streaming the event through the NOW platform, which offers a contract‑free way to watch boxing alongside other sports and entertainment content.

Beyond the immediate fallout, Smith’s career trajectory remains impressive. His ascent began with a series of victories on the domestic circuit, culminating in the high‑stakes showdown with Matias. That fight was not without controversy: Matias tested positive for a prohibited substance in November of the previous year, prompting an investigation.

After a thorough review, the anti‑doping authorities concluded that Matias, then 33, had not breached the regulations, clearing him of any wrongdoing. The Matias bout itself showcased Smith’s resilience and tactical acumen. Early in the fight, the Puerto Rican challenger applied pressure with a series of sharp uppercuts and combination punches, testing the British boxer’s defense. However, Smith adapted quickly, using his jab to control distance and timing his power shots to exploit openings.

The decisive right hook in the fifth round not only secured the knockout but also marked Matias’s first professional loss, dropping his record to 23‑3. Looking ahead, Smith’s camp will focus on his recovery and planning his next move once he is medically cleared.

In the world of boxing, injuries are an ever‑present risk, and fighters often have to adjust timelines and opponents accordingly. Fans can expect an announcement regarding a future defense once Smith’s health permits a return to the ring.
