Dalton Smith Withdraws from WBC Super-Lightweight Title Fight Against Alberto Puello Due to Injury

Dalton Smith has been forced to withdraw from his upcoming WBC super-lightweight title defense against Alberto Puello due to an injury sustained during training. The fight, originally scheduled for June 6 at Utilita Arena in Sheffield, was set to mark Smith’s first defense of the world championship he claimed earlier this year. The withdrawal deals a significant setback to the British boxer’s momentum and leaves the card without its original main event.

Injury Forces Withdrawal Ahead of High-Stakes Bout

The news was confirmed by Matchroom Boxing, the promotion organizing the event. A spokesperson for the organization stated that Smith had been ruled out after suffering an injury in camp, though specific details about the nature or severity of the injury were not disclosed. The announcement follows a period of intense preparation for Smith, who had been training to defend his title against Puello, a formidable contender in the 140-pound division.

Smith, 29, captured the WBC super-lightweight title in January 2026 with a dominant unanimous decision victory over former champion Jose Zepeda. The win solidified his status as one of Britain’s rising stars in boxing and set the stage for a high-profile showdown against Puello, a undefeated Dominican fighter known for his technical prowess and resilience in the ring. Puello, who holds a perfect record, was expected to provide Smith with his toughest test to date.

Card Reshuffled as Promoters Scramble for Replacement

With Smith’s withdrawal, Matchroom Boxing has been forced to reconfigure the June 6 card in Sheffield. While no official replacement main event has been announced, reports indicate that promoters are exploring options to elevate another bout to headline status. The undercard, which includes several high-profile matchups, remains intact, though the loss of the original main event is a blow to the event’s overall appeal.

The reshuffling of the card underscores the challenges promoters face when injuries disrupt carefully planned fight schedules. Smith’s absence not only deprives fans of a highly anticipated world title fight but also raises questions about his recovery timeline and future availability. For Puello, the withdrawal represents a missed opportunity to challenge for a world title, though his team is likely to push for a rescheduled bout once Smith is medically cleared.

Smith’s Title Reign Faces Early Test

Smith’s reign as WBC super-lightweight champion has been brief but impactful. Since claiming the title, he has been vocal about his desire to unify the division and establish himself as the dominant force in the 140-pound weight class. His scheduled defense against Puello was seen as a critical step in that journey, offering him a chance to prove his credentials against a top-tier opponent.

The injury adds an unexpected hurdle to Smith’s ambitions. While the severity of the setback remains unclear, the timing is particularly unfortunate given the momentum he had built following his title-winning performance. For now, Smith’s focus will shift to recovery, with his team likely to provide updates on his condition in the coming weeks. In the meantime, the boxing world will be watching closely to see how Matchroom Boxing adapts to the change and whether a new main event can salvage the Sheffield card.

Puello Left Waiting as Division Moves Forward

For Alberto Puello, the withdrawal is a frustrating development. The 30-year-old Dominican fighter has been on the cusp of a world title shot for years and the matchup against Smith represented his best chance yet to claim a championship. Puello’s undefeated record and technical skill have made him a respected figure in the super-lightweight division, and his team will be eager to secure another opportunity in the near future.

The broader implications of Smith’s withdrawal extend beyond the immediate fight. The super-lightweight division is one of the most competitive in boxing, with multiple champions and contenders vying for supremacy. Smith’s absence from the ring could create an opening for other fighters to make their move, potentially altering the landscape of the weight class. Fans and analysts alike will be monitoring how the situation unfolds, particularly as other titleholders in the division continue to schedule defenses and unification bouts.

What Comes Next for Smith and the Sheffield Card

As of now, no official timeline has been provided for Smith’s return to the ring. The boxer and his team have not issued a public statement regarding the injury, leaving fans and media to speculate about the extent of the setback. Historically, injuries in boxing can range from minor setbacks requiring a few weeks of rest to more serious issues that could sideline a fighter for months. Smith’s next steps will depend on the nature of his injury and the recommendations of his medical team.

For the June 6 card in Sheffield, Matchroom Boxing faces the challenge of delivering a compelling event without its original main event. Promoters have experience in navigating such situations, often elevating a strong undercard fight to headline status or securing a last-minute replacement. However, the loss of a world title fight is difficult to replace, and the success of the event may hinge on the strength of the remaining bouts and the ability to generate excitement around a new main event.

The situation also highlights the unpredictable nature of boxing, where injuries and other unforeseen circumstances can disrupt even the most carefully planned events. For Smith, the focus will be on recovery and ensuring he returns to the ring in optimal condition. For Puello, the wait for a world title opportunity continues, though his team is likely already exploring alternative paths to a championship bout.

As the boxing community processes the news, one thing is clear: the super-lightweight division remains as dynamic and unpredictable as ever. Smith’s withdrawal is a reminder of the physical demands of the sport and the fine margins that separate success from setback. Fans will be hoping for a swift recovery for the champion and a resolution that keeps the division moving forward.
