Anthony Joshua's highly-anticipated fight with Jarrell Miller is in jeopardy after the American failed a drug test, sources claim.
According to ESPN, as confirmed by Eddie Hearn on Twitter, Miller tested positive for the banned substance GW1516 on March 20 in a Voluntary Anti-Doping Association-conducted urine test.
AJ and Miller were due to fight at New York's Madison Square Garden on June 1, but a new opponent may have to be found.
Dropping out of the fight would cost Miller millions after he accused Joshua of using performance enhancing drugs (PEDs) in February.
"We are in the process of obtaining further information about VADA's finding and will have more to say soon on this developing situation," Miller's co-promote, Dmitriy Salita, told ESPN.
"In the meantime, Jarrell continues to train for his June 1 fight against Anthony Joshua."
In response to the breaking news, 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."
