The World Boxing Association has approved Gennadiy Golovkin's request for a special permit to move up in weight for the upcoming trilogy fight with undisputed super middleweight champion Saul 'Canelo' Alvarez, which is scheduled to take place on September 17th at the T-Mobile Arena in Las Vegas.
Earlier this year, Golovkin traveled to Japan and stopped Ryota Murata to unify the WBA, IBF, IBO middleweight titles.
The WBA's "regular" champion at 160-pounds is Erislandy Lara.
Should Golovkin defeat Canelo, he will only have five days - until September 23 - to advise the WBA as to which world title he intends to keep.
If he decides to return back to middleweight, he will have 120 days to defend his title against Lara to establish a single WBA champion at 160-pounds.
And if Golovkin loses to Canelo, he will also have 120 days to defend his title against Lara to establish a single WBA champion at 160-pounds.
The WBA has made it clear that their organization will not grant any further special permits for Golovkin.
Should Golovkin drop the WBA belt, then Lara would automatically get elevated to the status of 'super' champion at middleweight.
