Anthony Joshua brushed off Jarrell Miller’s taunts after the pair came face-to-face in London to promote their world heavyweight title fight.
IBF, WBA and WBO champion Joshua will fight in the United States for the first time as a professional in New York on June 1.
That bout will also represent the first fight for a world title for Miller, who in 2014 was given a nine-month suspension by the California State Athletic Commission for the banned stimulant methylhexaneamine.
The 30-year-old said he had noticed a change in Joshua’s physique, although added that he believes the Briton will be clean when the pair meet at Madison Square Garden.
Joshua, who has never failed or rejected a drugs test, responded: “He’s looking at my change between 2012 and 2013 but why doesn’t he look at the 11 years?
“Around the Olympics I was around 104kgs, then when I turned pro I was around 107kgs, so that’s around half-a-stone. I am 115kgs, so that’s 11kgs in 11 years; it averages out. It’s just my dedication.
“It’s not the first time this has happened. So many fighters will be accused but I get tested and if, in the next 10 years, something was to come up then it would be a genuine mistake because I do not shove needles up my a***.”
Miller revealed that both fighters have agreed to between 10 and 12 weeks of drug testing in the build-up to the bout.
Joshua confirmed: “I am on (drug testing scheme) ADAMS whereabouts, they have to know where I am for an hour every day and could walk in anytime.
“They can turn up any time during the day and that is a lifetime commitment. I have been on that since 2012 and I pay £40,000-a-fight to be tested by VADA two times a week.
“Jarrell Miller has been banned for drugs, so maybe that’s why he’s saying it.”
Chris Eubank Jnr is to explore returning to middleweight after reviving his career with a victory that leaves James DeGale facing retirement.
The 29-year-old dominated their grudge super-middleweight match-up at London’s O2 Arena, knocking DeGale down twice to secure the finest win of his career and put himself back into contention for a world title challenge.
He has been fighting at 168lbs since February 2017, yet continued to appear a natural middleweight. He had long suggested a return there would give him his greatest chance of success.
A lucrative offer to compete in the World Boxing Super Series and then his rivalry with DeGale ensured he remained there, but his father and manager Chris Eubank Snr, who excelled in both divisions before retiring after successive defeats at cruiserweight, is encouraging him to return.
Saturday’s victory was also Eubank Jnr’s first under his new trainer Nate Vasquez, and came as he demonstrated significant signs of improvement, ultimately ensuring that they will continue to work together.
“This was a career-defining fight for me, this was make or break, do or die,” he said. “I had to win, I had to make a statement, and I believe that’s exactly what I did.
“I want to challenge for world titles, I want to fight big names, the best in the middleweight or super-middleweight division. I can make both weights; whatever’s put in front of me, whatever the best route is, I will take.
“It’s extremely satisfying. (DeGale) saying that I can’t mix it at world-level, I can’t beat the top guys, I needed to prove that wrong. He managed to get a lot of people to believe that. So now hopefully I’ve turned some of the doubters, haters, into believers.
“I didn’t think he had it in him to get up after two heavy knockdowns like that, to keep going, and take those big shots. Respect to him for that.”
DeGale confirmed post-fight that he is likely to retire, and when asked about Vasquez’s influence and a potential rematch with Billy Joe Saunders, Eubank Jnr said: “Nate brought focus to the preparation. He brought a tailored, focused training camp, which I’ve never really had before.
“I had the right sparring, was working on the right things, for James DeGale. For all my previous fights, all my biggest fights it was just get fit, spar whoever’s in the gym, and fight.
“For this we studied, had a strategy, and that’s what we’ll continue to do for my future fights.
(Me and Saunders have) got a lot of history. I look at that and the rivalry we have; it’s tough not to want that fight.”
The 52-year-old Eubank Snr added: “He fought at 12 stones. He’s a middleweight, and that’s what we’re going to discuss, and look forward to competing at again.
“It may be time to come back down, but it’s something we will discuss as a team. He’s a true middleweight.”
Chris Eubank Jr has left James DeGale facing retirement after securing the finest victory of his career via a unanimous decision in their IBO super middleweight title match in London.
He had previously lost his two biggest fights, against Billy Joe Saunders and George Groves, but improved sufficiently to win an occasion DeGale said would force the loser to retire.
At 29 and with so high a profile there was little risk of that for Eubank Jr, but after his third defeat and a career in which he became the first British Olympic gold medallist to win a world title DeGale – the loser by scores of 114-112, 115-112 and 117-109 – has been left with few lucrative options to pursue.
The key was always likely to be whether DeGale retained enough of the abilities that once made him the IBF super-middleweight champion, which he both won and defended outside of his home city and in the US.
Until his bruising and damaging draw with Badou Jack he was sufficiently skilled and mobile to beat Eubank Jr, a natural middleweight, with ease but since then – in a defeat and then an unconvincing victory over Caleb Truax – he has struggled.
Even as the naturally smaller fighter there was every chance Eubank Jr possessed the physical – if not technical – advantages to impose himself.
It had been a year since he had lost so convincingly to Groves, owing largely to his size disadvantage and technical flaws, that in preparation for DeGale he had hired a new trainer in the little-known Nate Vasquez.
Following a cagey opener, Eubank Jnr hurt DeGale with a powerful left hook in the second that sent him into the ropes, and he followed up with a hurtful barrage that forced referee Michael Alexander to administer an eight count.
He was under similar threat at the start of the third, following a right hook that knocked him back, but after easing the pressure on himself and regaining his composure, he boxed with greater confidence in the fourth and fifth, landing with sharp jabs and evading the hooks his rival threw.
It was when DeGale began to move that Eubank Jnr began to look clumsy, swinging and missing with the type of punches that would test his conditioning, but for all that the older fighter’s defence often impressed, he was again guilty of throwing too little in return.
Eubank Jr remained a constant danger, disrupting DeGale with his aggression and maintaining the superior work-rate without being discouraged when he missed or was caught.
Another right landed towards the end of the eighth demonstrated that dominance, and a big 10th ultimately proved enough to secure victory. A left hook after they exchanged rights wobbled DeGale, before another barrage sent him to the canvas again.
If DeGale was already so far behind he required a knockout, he was given a lifeline when Eubank Jr was deducted a point for throwing him down in the 11th.
But in the 12th he did too little to win while also again being hurt, putting the result beyond doubt.
Eubank Jr told talkSPORT: “I’m back on top. I proved the doubters wrong.
“This is one of those fights which puts me in position to challenge for world titles now and I’m very happy.
“There was massive presssure. We were both on the edge of this cliff and someone’s was going to fall – and whoever falls can’t come back. I’m still here now, onwards and upwards.
“He’s a difficult fighter but I thought I dominated the entire fight.”
Asked whether Billy Joe Saunders could be his next opponent, Eubank said: “I’m not looking at him first and foremost, I don’t think he deserves it.
“There are other big names in the middleweight division…but there’s no one i wouldn’t fight. I’m here to collect the belts, whatever’s put in front of me I’ll take.”
Joe Joyce earlier secured the biggest victory of his professional career by stopping former WBC heavyweight champion Bermane Stiverne in six rounds.
There was also a win for Wales’ Lee Selby, who beat Omar Douglas at lightweight via a unanimous decision and scores of 116-112, 116-112 and 115-114.
