The middleweight champion has found a replacement for Canelo Alvarez, who has been suspended for six months by the Nevada Athletic Commission for failing two drug tests.
The former two-weight world champion, and current lineal champion, recently pulled out of a high-profile rematch with Gennady Golovkin following a positive test for the banned substance clenbuterol.
Golovkin called him a liar and implied he had always been a doper and accused him even further, stating he was doping during their first bout as well.
They announced his next bout will take place on September 15, Mexican independence weekend, and it is believed this will likely be the rescheduled Gennady Golovkin rematch. It's a good show for L.A. Cinco De Mayo.
The 27-year-old had blamed the failed tests on eating contaminated meat in his native Mexico and insisted he was the victim of a mistake.
Gennady Golovkin getting stripped of the IBF title would be a blow to his hopes of unifying the middleweight division.
Alvarez's suspension included a mandate that he must pass drug tests before he fights again in Nevada. "And our guy is in the gym and ready to fight". Though the fight is not official, Golovkin's promoter Tom Loeffler and Martirosyan's promoter Don King are reportedly close to finalizing a deal while the California State Athletic Commission (CSAC), WBA and WBC have all sanctioned the fight.
Crucially, however, the second six months have been suspended because Alvarez co-operated with the NSAC.
"I am truly shocked about what has happened and for those who have doubts and suspicions about my integrity".
"I want to apologize to all my sponsors, the media and to everyone who is involved in the promotion of this event and especially to the fans".
But with Alvarez suspended there was too little time between the hearing and the fight do promoters chose to cancel the bout. Golovkin has sold out the most iconic arenas of the world, including T-Mobile Arena, Madison Square Garden, O2 Arena, The Fabulous Forum and StubHub Center.
