Anthony Joshua’s world heavyweight title fight against Jarrell 'big baby' Miller is in doubt after the American allegedly failed a drug test.
Miller is said to have tested positive for the banned muscle growth substance GW1516, a metabolic modulator also known as cardarine and endurobol, from a test sample that was taken on 20 March and a second sample may now be tested.
The 30-year-old is likely to face a hearing before the New York State Athletic Commission to decide if he would be allowed to fight on June 1.
Both camps have confirmed that the Voluntary Anti-Doping Association had informed them of an 'adverse finding' in Jarrell Miller’s sample.
Matchroom Sport promoter, Eddie Hearn, tweeted: "We have been informed by VADA that there has been an adverse finding in Jarrell Miller’s sample collected on March 20th, 2019.
"We are working with all relevant parties and will update with more details soon. AJ’s preparation continues for June 1st at MSG.
Miller, who is undefeated in each of his 24 professional bouts, could lose a career-high purse of $4.875million which, according to ESPN, would be his percentage of UK pay-per-view profits.
That's not including the millions he would have raked from a rematch if he won. However, he would have also still made seven figures again had he lost.
AJ’s US broadcaster, DAZN, also reached an agreement with Miller that guarantees him two comeback fights worth $1.5million each and that could now be scrapped.
The fight was due to take place at the Madison Square Garden for the WBA, IBF, WBO, and IBO titles on 1st June.
