Footage has emerged of Daniel Dubois's 'insane' 70-person house party thrown in the hours before his defeat by Oleksandr Usyk on Saturday.
Other boxers have blasted the bas, which was reportedly laid on by his father for people Dubois did not know, as a 'disruptive' interference with his day.
As it happened, Dubois was knocked out by Usyk in the fifth round at Wembley as he lost out on the chance to become the undisputed heavyweight champion of the world.
Videos from the party show Dubois smiling and posing for photos with attendees, with dozens of people packed into the house and overflowing onto the property's driveway.
The Times reported that Dubois' father, Stanley, grew 'agitated' that his son was set to bank £150million, when the actual fee was around £10 million, and threw a lavish occasion at their family mansion in Essex.
Later, Stanley requested extra vehicles to take the entourage to Wembley, with only one of the vehicles accredited to park, meaning Daniel had to walk to the stadium on foot. Stanley also reportedly threatened that his son would not go ahead with the fight if his expanded posse were not allowed in.
On talkSPORT, other boxers could scarcely believe what they were hearing as Simon Jordan related what had happened to them.
'That is insanely disruptive,' said Joseph Parker. 'I'm very surprised, I'm shocked. That many people over? You're preparing for a massive fight.
'You need rest, you need to chill, you need to get in the zone,' and he's got this big party happening.
Lawrence Okolie concurred: 'The problem is, it's coming from someone that he looks (to) out of the ring. It's coming from his dad.
'I've trained with him; his dad's a huge part of his life, so that is going to be disruptive.'
Spencer Oliver added: 'We're talking about fighters being regimental and superstitious on the day, some fighters want to wear a ring in their laces and all that stuff.
'It all has to be on point for you to go in there; any little thing can throw you off track.'
Dynamite was always going to be up against it, taking on Usyk, who has since been crowned one of the best three heavyweights ever by Mail Sport's Jeff Powell.
