The fight every boxing fan wants to see is apparently a done deal - but you're going to be waiting a long time before you see it. A report from Lance Pugmire of the LA Times states that the promoters have come to an agreement for the two men to meet in the Fall of 2017 at 160 pounds:

Canelo Alvarez and @GGGBoxing promoters have struck deal for them to fight in fall of 2017 according to Times' source. — Lance Pugmire (@latimespugmire) June 22, 2016

.@Canelo will return to 154 for a fight on Sept. 17 and gradually move up to 160 for @GGGBoxing says source. — Lance Pugmire (@latimespugmire) June 22, 2016

Thinking for now is that @Canelo will have at least "a couple fights" before @GGGBoxing showdown, source tells me. — Lance Pugmire (@latimespugmire) June 22, 2016

Deal struck source says following meetings that originated with trip two days ago to Golden Boy offices by @GGGBoxing promoter @TomLoeffler1 — Lance Pugmire (@latimespugmire) June 22, 2016

The bout represents the biggest matchup available among active fighters at the moment, and has been rumored for a long time. After Alvarez stopped Amir Khan last month, the bout seemed inevitable. But Alvarez dropping the WBC middleweight belt (which was subsequently awarded to Golovkin) cooled things off and the promoters weren't talking.

Until two days ago, apparently.

In the meantime, Alvarez is scheduled to fight in September against a yet-unnamed opponent who could end up being Chris Eubank Jr (though he's rumored to fight Triple G as well). Golovkin's promoter Tom Loeffler has stated that he'd like Golovkin to fight twice more in 2016.

Hopefully things stay on schedule and we get to see this actually happen.
