Promoter Eddie Hearn is not concerned at all, after WBA, IBO, IBF heavyweight champion Anthony Joshua (19-0, 19 KOs) weighed in at a career-high weight of 254-pounds.

Joshua's previous high was 250-pounds, which he weighed in at for his last ring appearance - an April TKO win over Wladimir Klitschko before a crowd of 90,000 at Wembley in London.

On Saturday, he will have nearly 78,000 fans watching as he faces Carlos Takam at the Principality Stadium in Cardiff, Wales.

Last week, Hearn made a prediction that Joshua would come in lighter than his previous career weight, but the Matchroom promoter now believes that his boxer is still maturing at the age of 28.

In the opinion of Hearn, Joshua looks better and fitter than he did for the career defining win over Klitschko.  He says it's unlikely that Joshua will weigh any lighter than 250-pounds going forward.

"He's been light in camp," Hearn told Sky Sports. "Obviously he's got a chef up in the house, who is feeding him well.

"He doesn't monitor his weight, but he looks a lot leaner than the Klitschko fight and he feels a lot leaner, but he's come in heavier. I think his set even looks different, I think he looks more athletic and leaner in this fight. Like he said in the interview, he's not out there to make weight, he's just preparing the best way and whatever it comes on the scales it comes.

"He's growing now into a mature man. Maybe this is his natural weight? I don't think you're going to see him come in much lighter than this."

Carlos Takam, a late replacement for an injured mandatory challenger Kubrat Pulev of Bulgaria, only weighed 235.5-pounds - which is his lowest weight in several years. Takam has weighed in as high as 257-pounds. He was a shade over 241 for his close decision loss to current WBO champion Joseph Parker.
