There’s major breaking boxing news this afternoon after Anthony Joshua’s American debut is now in serious jeopardy after his challenger Jarrell “Big Baby” Miller allegedly tested positive for a banned substance.
It’s understood that Miller failed a doping test for banned substance GW1516.
The heavyweights were scheduled to fight on June 1 at New York’s Madison Square Garden, with Joshua defending his WBA, WBO and IBF heavyweight titles.
Miller, although an outsider, is a behemoth of a man in both stature and personality.
Ahead of the fight, the pre-sale tickets took just two hours to sell out and broke an MSG record. It became the highest grossing pre-sale in the history of the arena.
The results have come to public attention after a Voluntary Anti-Doping Association-conducted urine test Miller submitted to on March 20th.
GW1516, also known as cardarine and endurobol, is on the World Anti-Doping Agency’s banned list and classified as a metabolic modulator. It must be said that the list has been criticised in the past for being too long and having far too many substances on it.
