Tyson Fury, who previously held the Ring Magazine belt, spoke out against Joshua after the defeat which left him as the top ranked heavyweight.

"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."

Rumours of a pre-bout panic attack have been circulating, but Joshua has denied worries.

"I had no panic attack," he said. "I have to take my loss like a man. No blaming anyone or anything.

“There have been a lot of accusations and worries about what was wrong with me.

“I want to tell you this: I am a soldier and I have to take my ups and my downs - and on Saturday I took a loss."

Joshua has already triggered his rematch clause, and will look to have reclaimed his world titles by the end of the year.
