Jarell Miller insists he is not a drug cheat after testing positive for a banned substance.
Miller was due to fight with Anthony Joshua who defends his IBF, WBA and WBO titles at Medison Square Garden in New York on June 1.
The American could now face a ban after testing positive for GW1516, a substance which increases aerobic power and endurance.
Miller has yet to speak out about the test but Sarah Fina, vice president of operations for his promotional company, tweeted: "
Jarrell obviously denies the allegations... in no way shape or form do I condone cheating, but for now I stand by our fighter."
This is not the first time that Miller has failed a drug test. Back in 2014, when Miller was kickboxing with GLORY, he tested positive and was suspended for nine months.
