Heavyweight contender Jarrell “Big Baby” Miller has tested positive for the banned substance GW1516 ahead of 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 test results, which came to light Tuesday, were from a random Voluntary Anti-Doping Association-conducted urine test Miller submitted to on March 20.
Ironically, Miller accused Joshua of using PEDs during their press tour to announce the fight.
