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 his first opportunity to protect the belt he captured from Subriel Matias in January.
Smith’s victory over Matias, a hard‑hitting Puerto Rican contender, earned him the WBC super‑lightweight championship and placed him alongside a distinguished group of British fighters who currently hold world titles. Alongside heavyweight Fabio Wardley, welterweight Lewis Crocker, super‑featherweight Jazza Dickens and featherweight Nick Ball, Smith now joins a rare cohort of male world champions representing the United Kingdom on the global stage. The injury that sidelined Smith was reported to have occurred during a routine training session in his Sheffield camp. While the exact nature of the injury has not been disclosed, the decision to pull the fight was made in consultation with his medical team, who concluded that competing would jeopardize his health and future performance.
Consequently, the main event slot at the Utilita Arena has been reassigned. Organisers have turned to Galal Yafai, the British flyweight who holds both the WBC and WBA titles, to headline the evening.
Yafai will now face Ricardo Sandoval in a unification bout that promises to deliver the excitement originally expected from the Smith‑Puello clash. The change maintains the night’s appeal for the local crowd and ensures that the arena still showcases a world‑title fight. Smith entered the ring against Matias in Brooklyn with a flawless 18‑0 record.
The fight ended dramatically in the fifth round when Smith landed a powerful right hook that sent Matias crashing to the canvas. The referee intervened and stopped the contest, awarding Smith a knockout victory and cementing his 19‑0 record. Earlier in the same round, Smith had already found the range with another crisp right hand, demonstrating his ability to combine speed, precision, and power. The Matias bout was not without controversy.
After the fight, Matias tested positive for a prohibited substance in November, prompting an investigation that threatened to overturn the result. However, a month later the anti‑doping panel cleared the 33‑year‑old, determining that there was no breach of the sport’s drug policy. The decision allowed Smith’s win to stand and preserved his status as an unbeaten champion.
Matias had given Smith a challenging start, employing aggressive uppercuts and a flurry of combination punches that tested the Brit’s defensive instincts. Smith weathered the early storm, adjusted his tactics, and ultimately turned the tide, delivering the decisive blow that ended Matias’ career as a professional with a record of 23‑3. Looking ahead, Smith’s recovery timeline remains uncertain, but his camp has indicated that he intends to return to the ring as soon as medically feasible. A future defense against Puello or another top contender is still on the horizon, and fans can expect the champion to come back stronger after a period of rest and rehabilitation.
