Tyson Fury's sympathetic response to Anthony Joshua's defeat by Andy Ruiz Jr didn't last long.
Moments after Joshua lost his heavyweight world titles on Saturday night, Fury tweeted: "We have our back and forths but Anthony Joshua changed his stars through life.
"Heavyweight boxing, these things happen, rest up, recover, regroup and come again."
But the former world champion has now adopted a different tone as he prepares for his return to the ring against Tom Schwarz next weekend.
"He’ll never live it down," Fury told ESPN radio.
"Can you imagine? You're built like an Adonis, you’re six-foot-six, you’re ripped, carved in stone, and a little fat man who has eaten every Snickers and Mars bar in California comes in there and bladders you all over? What a disgrace.
"If that was me, I would never show my face in public ever again."
Fury has not fought since his controversial draw with Deontay Wilder last December.
He, as Joshua was, is expected to deal with Schwarz comfortably when they meet in Las Vegas on Saturday week.
And Fury appeared to soften his stance on his rival almost immediately when he added: "The way I see it, Joshua has done very well for himself out of boxing.
"He came from nowhere, he came out of the gutter, brought up with no money, he changed his stars and changed his life.
"He’s probably worth $70million, he’s done well in his life and career. He’s been the heavyweight champion of the world. If that’s a failure then I don’t know what isn't a failure.
"He’s definitely done well in his career, but everybody bumps into that one person that can knock them out any time.
"Unfortunately for AJ, it was the little fat fella from California who chinned him."
