Promoter Frank Warren is shaking his head at the recent events with respect to heavyweight contender Jarrell Miller.

Miller was scheduled to face IBF, IBO, WBA, WBO world champion Anthony Joshua on June 1 at Madison Square Garden in New York City.

But earlier this week, news broke that he tested positive for banned substance, and then Miller was denied a boxing license by the New York State Athletic Commission, after their officials were informed by Voluntary Anti-Doping Agency (VADA) that Miller came up positive for a performance enhancer.

The hunt is underway to find Joshua an opponent.

Joshua, promoter, Eddie Hearn, has already made it clear that there is zero intention of pushing back the date.

At the moment, the frontrunner to replace Miller is reportedly once-beaten Michael Hunter.

“The one result they’ve had out of all of this is that they have time to find a replacement – they’ve got five or six weeks before the fight, it’s lucky not having it on the week of the fight,” Warren said to Talk Sport.

“As far as Miller is concerned, that’s his lot. He shouldn’t be licensed and if he is drugging, he needs to be chucked out of the sport. Simple as that. Opponent? That’s the problem they’ve got. The fight is in New York and the Yanks will be looking for one of their own and I’m not sure who they’re going to find to be in the opposite corner to AJ. The guy that you would like to see in there with him and a guy that deserves the opportunity is Dillian Whyte.

“But, that’s two Brits fighting each other in New York and I don’t think that’s a strong selling point."

Miller has come out and denied that he "knowingly" took any PEDs to prepare for the fight.

Warren believes there could be a hint of truth in that statement, but at the end of the day the fault is strictly placed on the boxer for everything that he ingests.

"What I will say is, I think there is very, very, very few boxers that actually go out and buy supplements and performance enhancing drugs – I don’t believe there is many boxers who would do that," Warren said.

“I think that comes through the trainers. It’s trainers or nutritionists saying ‘try this, try that’ and as much as at the end of the day the boxer should be and is accountable, we should also look to where they’re getting this stuff from. And that is part of the problem. If he is saying he never knowingly took anything, then who gave it to him to take? That’s the answer, isn’t it?”
