Callum Smith will make the first defence of his world titles against Hassan N’Dam.

The WBA Super, WBC Diamond and Ring Magazine super-middleweight champion will take on the former middleweight WBA ‘regular’ champion on June 1.

Smith is set to meet the French-based Cameroonian at Madison Square Garden in New York.

The fight will form part of the supporting cast to Anthony Joshua’s defence of the WBA Super, IBF, WBO and IBO world heavyweight titles against Andy Ruiz, exclusively live on Sky Sports Box Office in the UK and DAZN Stateside.

“I’ve had a good camp and I’m looking forward to walking to the ring as a world champion for the first time in my career,” said ‘Mundo’. “I worked so hard to get where I am and now the task is to keep hold of my titles and target those big fights.

“To have my first defence at Madison Square Garden is going to be special and it’s another box ticked for me personally. People call it the Mecca of Boxing and I’ve always seen it as a venue that I’d love to fight at one day.

“The minute that there was a chance of it happening I pushed to make sure that I could be part of this show.”

N’Dam outpointed St Helens’ Martin Murray last December to clinch the WBC Silver title down at middleweight but has been out of action since.

“N’Dam is a good fighter and he’s a former world champion. He’s only lost to three top fighters and he’s got some great wins on his record. I had him over in England to help me prepare for George Groves so we know each other well. He’s a good mover, has good footwork and can move around the ring pretty well. Experience is on his side and he’s an awkward guy to face.

“I believe that I’m improving all of the time – I’ve even improved since winning the title. I believe that I’m the best in the world.

“There are a few fighters in my division who probably disagree with that and rightly so. If I am the best on the planet then I should be able to get rid of Hassan N’Dam and look good doing it.”

N’Dam, meanwhile, believes he will have what it takes to beat Smith, whose brother Liam recently signed a promotional pact with Eddie Hearn and Matchroom Boxing.

“I am confident I will create a big surprise in New York,” he said. “It is a true privilege for me to be given the chance to fight at Madison Square Garden for the first time in my life. At this stage of my career, this is a beautiful opportunity for me to be able to change division and fight for the titles.

“I am so pleased and proud for this opportunity to be offered to me and I would like to add that even though the challenge is a big one, this does not affect my focus and my determination. Callum Smith is an excellent boxer with many qualities. As he is tall he can impose his own boxing style on most of his opponents. I have much respect for him both as a boxer and a person. I believe it will be a very tactical fight.

“Being able to say that once in my life I have fought at MSG will be a great pride. I have the experience of boxing on big shows as I have participated in many and in front of thousands of people.

“I have always defended my titles abroad so I am used to pressure and know how to handle it.”
