Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, views once-beaten Mexican contender Andy Ruiz as a very dangerous opponent to face on short-notice.

Ruiz is a frontrunner to face Joshua on June 1 at Madison Square Garden in New York City.

"Andy Ruiz will come to win. He doesn't look physically pleasing, but he can really fight. He's Mexican, he can punch, he has fast hands, and he knows how to fight," Hearn said.

Joshua was scheduled to face Jarrell Miller, who was pulled from the contest after failing three pre-fight drug tests.

According to Hearn, Joshua is not worried at all about his next opponent.

"[He's] Absolutely fine. He’s the ultimate pro. He’s impressed me so much. He hasn’t even asked me. It’s been nearly eight days or nine days since [Miller’s first failed drugs test]. I’d have liked to have announced it a couple of days ago but it won’t be long.”

Hearn believes Ruiz or Michael Hunter would come in there and really make it a way with Joshua.

“Don’t fight him for the money, fight him for the world heavyweight title because you think you can win. Those are the people I want. I don’t want to go to Madison Square Garden and watch him bowl someone over in a round, I want to see him in a war, I want to see someone trying to take his head off - legally," Hearn said.

“I want someone that thinks they can win rather than someone who goes, ‘If you give me this much, I’ll take it.’ I’m not interested in that. I know you’ve got to get as much money as you can but come to win, because it’s a life-changing moment. The world heavyweight championship at Madison Square Garden, that’s something you dream of.”
