A heavyweight showdown featuring unified champion Anthony Joshua and challenger Jarrell ‘Big Baby’ Miller is in danger.

Dan Rafael of ESPN reports that Miller tested positive for the banned substance GW1516 ahead of the June 1 bout in New York.

BREAKING: Heavyweight contender Jarrell “Big Baby” Miller has tested positive for the banned substance GW1516 ahead his scheduled challenge of unified world titleholder Anthony Joshua, three sources with knowledge of the results told ESPN on Tuesday night. The fight is due to take place on June 1 at New York’s Madison Square Garden and serve as Joshua’s American debut. The results, which came to light on Tuesday, were from a random Voluntary Anti-Doping Association-conducted urine test Miller submitted to on March 20. Ironically, Mille accused Joshua of using PEDs during their press tour to announce the fight.

According to

GW501516 (GW1516 or GSK-516) is a drug that acts as a PPARδ modulator. GW 501516 activates AMP-activated protein kinase and stimulates glucose uptake in skeletal muscle tissue, and GW 501516 has been demonstrated to reverse metabolic abnormalities in obese men with pre-diabetic metabolic syndrome, most likely by stimulating fatty acid oxidation.

Joshua’s promoter Eddie Hearn tweeted that the team was aware of the findings but preparations for June 1 are ongoing.

Jarrell Miller’s co-promoter, Dmitriy Salita, tweeted the following:

Miller failed a drug test in 2014 while fighting under the Glory Kickboxing banner. Miller was suspended for nine months by the California State Athletic Commission for testing positive for methylhexaneamine (dimethylamylamine).
