Jarrell Miller has once again tested positive for performance-enhancing drugs and has therefore been pulled out of his return fight.
The unbeaten heavyweight had been scheduled to face Anthony Joshua last June, but he failed a series of VADA tests last year and as a result his place was taken by Andy Ruiz Jr.
Miller was set for another comeback against Jerry Forrest on July 9 this year having now signed a promotion deal with Bob Arum’s Top Rank.
But The Athletic were the first to report that Miller has failed another test and alleges the American has tested positive for GW1516, a drug used to aid endurance and boost aerobic power.
It is also understood that the substance is one of the same drugs which came up before the cancellation of his fight with Joshua.
Miller tested positive for human growth hormone, EPO and GW1516 and served a six-month ban as a result in 2019.
Top Rank confirmed the news shortly after it broke, with vice president Carl Moretti telling the same outlet: “We are aware of the situation.
“He will be placed on temporary suspension by the Nevada State Athletic Commission on Monday morning. We are currently filling the main event from July 9.”
Miller has therefore been pulled from the Forrest fight and his future in the sport is now in major doubt.
The Nevada Athletic State Commission recently decided to licence the 31-year-old, which paved the way for his return.
He has not fought since a win over Bogdan Dinu in November 2018 and will now face an uncertain future for an indefinite period.
Upon signing with Top Rank in January, Miller said: “Minor setback for a major comeback.
“I’m coming for everything and everyone. No one is safe. Say hello to the bad guy.
“Everyone wants to portray the superhero. We don’t live in a sunshine world.
“I’ll never be the superhero. In my world, the majority of the time, the villain wins.”
Despite his inactivity, the 31-year-old also claimed in April that he believes he is the best heavyweight in the world.
“I am number two in the world, the only reason I am not number one is because I don’t have no belt, I know I am a better fighter than all of these guys,” he told BonusCodeBets.co.uk.
“I’m better than AJ, I’m better than Tyson, I’m better than Deontay [Wilder], I only call myself number two because I don’t have that belt. I’m going to be world champ.”
