"Big Baby" Miller fails second drug test after testing positive for Human Growth Hormone

Heavyweight contender Jarrell "Big Baby" Miller has failed yet another drug test, this time for a different banned substance. According to ESPN, Miller tested positive for Human Growth Hormone (HGH).

On Tuesday, Miller (23-0-1, 20 KOs), 30, also tested positive test for the banned substance GW1516 (Endurobol), a result of a random urine test conducted by the Voluntary Anti-Doping Association (VADA) on March 20. The New York State Athletic Commission refused to issue Miller a boxing license, which cost him a shot at unified titleholder Anthony Joshua on June 1 at Madison Square Garden. According to ESPN, the HGH test was from a sample on a different date than the initial positive test.

Miller denied knowingly taken Endurobol, but now the cloud hovering above him has mounted an even more dominate position.

This is the third time that Miller has failed a drug test.When he competed as a kickboxer under the GLORY banner, he was suspended for nine months by the California State Athletic Commission after testing positive for Dimethylamylamine, which has been used in the past by athletes as a dietary supplement and a performance-enhancer. Miller was subsequently suspended for nine months.
