Following his second stoppage defeat to Oleksandr Usyk in July, Daniel Dubois (22-3, 21 KOs) has split with Don Charles and joined Tony Sims in Essex, as reported by On The Record Boxing.
The 27-year-old was taken apart with ease by the two-time undisputed heavyweight champion on July 25 in Wembley Stadium. Usyk was levels above the Londoner, who was knocked out in the fifth round.
Following the loss, trainer Kieran Farrell was quick to announce his departure from the team.

Following the shambolic build-up to the undisputed clash with Usyk, where the 27-year-old’s dad held a pre-fight party at his house, then threatened to pull his son from the fight if his unticketed entourage were not let into the stadium, Farrell sensibly stepped away from the team.
Farrell announced on August 13: “I have made the decision to part ways with Team Dubois.
“In the 18 months we’ve achieved so much, including an unforgettable night at Wembley stadium.
“Helping Daniel become world heavyweight champion has been truly rewarding on a number of levels. I wish Daniel all the best going forward.
“I won’t be making any further comment at present, but needless to say I'm excited for what’s next for myself and look forward to making many more world champions.”
Dubois' overbearing father has a track record for axing training teams, following stints with Martin Bowers at The Peacock gym and Shane McGuigan.

And now, Don Charles appears to be another casualty in a long line of sacked trainers.
It's not yet been confirmed if Daniel Dubois has linked up with trainer Tony Sims, who also looks after Conor Benn, and has recently been helping his nephew Joey Essex train for his upcoming MisFits fight on August 30.
Tony Sims has trained Conor Benn since the start of his career, with Conor's father Nigel having sparred with Tony in the past.
Throughout his career, Sims has trained many big names, including Anthony Joshua.
Tony is also the father of Demi Sims, who is also due to fight on the same Manchester event as Joey.
Now working exclusively with Matchroom Sport fighters, Sims's gym in Brentwood, Essex is called, 'The Matchroom Gym'.
Tony said, “When I started out training, I had a few club-fighters. Looking back I probably never thought I was going to be in a good position, because there were so many big promoters in those days and I was just chucking my fighters on little, tiny shows at the Elephant and Castle, just club shows, dinner shows, average fighters.
“I learned a lot in those days, corner work. I was fortunate enough to do a bit of cut work with legendary coach Ernie Fossey. Sometimes I was in the changing room with 'handler of journeymen' Nobby Nobbs because they were the calibre of fighters I had. I picked up a lot of good tips in those days. I worked in the changing rooms with Jimmy Tibbs, I worked alongside Jim McDonnell for a few years.”

Billy Nelson: "More trainers than JD Sports. No coach can install bottle to any boxer, that comes from within. Scandalous if true, Don [Charles] done well by him."
Anthony Fowler: "Should have stayed with McGuigan's gym, he was unbeaten and improving, shame his dad is greedy."
