Promoter Eddie Hearn says the Voluntary Anti-Doping Association has informed Anthony Joshua’s camp about an adverse finding in a sample collected from heavyweight opponent Jarrell Miller.
Hearn said the sample from Miller, scheduled to fight Joshua at Madison Square Gardens in New York on June 1, was collected on March 20 of this year.
Hearn tweeted: “We have been informed by VADA that there has been an adverse finding in Jarrell Miller’s sample collected on March 20th, 2019.
“We are working with all relevant parties and will update with more details soon. AJ’s preparation continues for June 1st at MSG.”
Joshua and Miller were due to fight for the WBA, IBF, WBO and IBO titles in New York.

Although Joshua’s preparations will continue, the VADA news leaves the Miller fight in doubt and a replacement fighter may need to be found for what would be Joshua’s USA debut.
As expected, plenty of boxers have already thrown their name into the hat, including Joseph Parker, Joe Joyce and Michael Hunter.
However, the biggest name has just recently admitted to being open to the fight, and that man is Dillian Whyte.
Whyte vs Joshua 2.0 was heavily reported to be the fight to take place in April at Wembley Stadium, but when that fell through, AJ turned his attention to the States.
Now, with Miller's future uncertain, Whyte has told talkSPORT that he is ready to step in.
Whyte said to Jim White: "I would take the fight with Joshua at the drop of a hat. If they want it, they can have it. I can whip myself into shape for the right opportunity."
Joshua retained his WBA, IBF, WBO and IBO titles when he stopped Alexander Povetkin in September.
Miller was kickboxing in 2014 when he tested positive for methylhexaneamine in a urine sample and was suspended for nine months by the California State Athletic Commission.
