Golovkin, of course, was originally scheduled to take on Canelo Alvarez, but Alvarez failed multiple drug tests and has since been suspended for six months.
At a hearing on the subject during the commission's monthly meeting, the five-member committee unanimously approved an agreement reached beforehand to shorten the suspension from one year.
Now that Alvarez is suspended, Golovkin will now face Vanes Martirosyan on May 5 from the StubHub Center in Carson, California.
Alvarez blamed contaminated beef in Mexico for his positive test and vowed to plead his case before the commission.

Alvarez (49-1-2, 34 KO's) tested positive for trace amounts of the substance in random urine tests conducted by the Voluntary Anti-Doping Association on February 17 and February 20 in his hometown of Guadalajara, Mexico.
