Terence Crawford finally returns to the ring.
Rated as one of boxing's Pound for Pound best, the American has perhaps slipped the mind of many after witnessing Oleksandr Usyk claim heavyweight gold and Saul 'Canelo' Alvarez continuing his dominance at 168lbs.
Usyk - now a two-weight champion - overcame Anthony Joshua via unanimous decision in London to claim the WBA, IBF and WBO belts and in doing so, is rated No.2 in the P4P rankings by Ring Magazine.
Canelo is the man above him in top spot. The Mexican is a four-division world champion and has wins over Sergey Kovalev, Callum Smith, Daniel Jacobs and more recently Billy Joe Saunders, who he beat on Cinco de Mayo weekend.
Before Crawford makes his highly-anticipated return, Canelo will fight before him once again in a super middleweight unification.
However, with Errol Spence Jr. out of action after suffering an eye injury, Crawford has a chance to stake his claim as the best welterweight in the world when he collides with Shawn Porter.
Crawford is a three-division king. Unified at lightweight, became undisputed champion at 140lbs and then beat Jeff Horn to add the WBO welterweight crown to his mantelpiece. Three defences have followed, including wins over Amir Khan and Kell Brook - his most recent bout 12 months ago - although both were deemed over the hill.
Does Crawford not get the credit he deserves?
Quite possibly. By American's he is rated as one of the best, if not the best fighter in the world when it comes to the Pound for Pound rankings. However, outside of the United States, there are question marks over his resume.
Similar to Gennadiy Golovkin, when he was coming through the ranks destroying everyone at middleweight, he simply does not have a big name in their prime on his record. Porter will put his friendship aside when he collides against Crawford and this is an all-American clash which will be an intriguing bout.
"Showtime" Shawn is a former two-time welterweight world champion with wins over Yordenis Ugas, Danny Garcia and Adrien Broner.
He has three defeats on his record to Brook, Keith Thurman and Spence. However, his most recent loss was a split decision verdict while the result against Brook could have easily gone in his favour.
Does he have enough in the tank to give Crawford problems?
It's a tough question to answer. Porter is a full-fledged welterweight who is one year younger than Crawford at 33. However, he is inactive having most recently fought 15 months ago and ring rust could play a huge factor.
Porter needs to start as the aggressor and take to the centre of the ring but it is easier said than done with Crawford having the ability to switch-hit and create angles as no other welterweight can right now.
The problem Porter will have is the longer the fight goes on, the more intense it will become as Crawford gets better as the rounds go on.
It is Crawford's last fight under Top Rank's Bob Arum as it stands and could very well be his last after Arum criticised Crawford for not being marketable enough. For someone of his ability, there will be plenty of interest in promoting Crawford should he look elsewhere.
We expect "Bud" to come through this test and with the welterweight division not as appealing as it used to be, we could very well see a super-fight next with Josh Taylor on the cards. Porter, though, is a live wire and a big underdog considering how good he still is.
When and where?
The fight will take place at Mandalay Bay in Las Vegas on November 21.
