ESPN.com reported late Friday afternoon that Miller failed a third drug test administered by the Voluntary Anti-Doping Association (VADA). A urine sample collected March 31 came back positive for EPO and for GW1516. Miller tested positive for the latter substance in a separate test whose results were revealed Tuesday.

The 30-year-old Miller (23-0-1, 20 KOs) was already in the process of being replaced for his scheduled clash with Anthony Joshua on June 1 at Madison Square Garden after the first failed test and subsequent denial of a license by the New York State Athletic Commission. He was going to appeal the decision but decided not to put up a fight after the third failed test was reported.
Miller made a video statement on Instagram admitting to his transgressions.
ESPN.com reported earlier Friday that Miller failed a second VADA test, for HGH; the site later reported the positive result came from a blood test taken March 31. It was reported Tuesday that VADA found GW1516 in a urine sample collected March 20.
A replacement opponent for Joshua in his United States debut will be announced next week.
