Heavyweight Daniel Dubois Splits Trainer Don Charles, Joins Tony Sims

Daniel Dubois has officially split from his trainer Don Charles following his fifth-round stoppage loss to Oleksandr Usyk at Wembley Stadium, where he lost the IBF heavyweight title. Dubois' partnership with Charles, which began before their first fight against Usyk in August 2023, saw significant success including knockout victories over Filip Hrgovic, Jarrell Miller, and Anthony Joshua, culminating in his IBF title win. However, after the defeat to Usyk and a tumultuous build-up involving a pre-fight party hosted by Dubois' family, both assistant trainer Kieran Farrell and Charles departed from the team. Dubois has now joined forces with Tony Sims, a respected trainer who previously guided Anthony Joshua to the IBF heavyweight title and currently trains fighters like Conor Benn, marking Dubois' fourth trainer in less than five years. The frequent changes in coaching staff highlight ongoing instability in Dubois' camp, raising questions about his discipline and career management. Sims faces the challenge of stabilizing Dubois' career and helping him regain his status as a top heavyweight contender.
