That fight will take place at Allegiant Stadium in Las Vegas on 13 September, as will the undercard, despite a tease by Saudi boxing chief Turki Alalshikh earlier this summer.
"The undercard, it will be between two or three days," Alalshikh said in July, speaking to The Ring, a magazine that he owns. "Imagine, for two or three days.
"We have now reached more than 20 fights to do on the undercard, and 90... 95 per cent of this card is talent and people around the world [who] have a very big chance to be a star in the future. [Thursday, Friday,] then Saturday. It must be something like this [a fight festival]."
As it stands, however, only nine undercard fights are official.
Canelo vs Crawford was originally due to take place on Friday 12 September, but it was then moved back by one day. It will now clash with a UFC Fight Night, despite the fact that UFC president Dana White is a co-promoter of Canelo vs Crawford.
Indeed, Canelo vs Crawford marks White's first major event as a boxing promoter, as he works alongside Alalshikh.
Crawford is a former lightweight, super-lightweight, and welterweight champion, who currently holds the WBA super-welterweight title. The unbeaten American, 37, was previously undisputed at super-lightweight and welterweight - one of just two boxers to have been undisputed at two weights in the four-belt era, alongside Naoya Inoue.
Meanwhile, Canelo is a two-time undisputed champion at super-middleweight. The Mexican, 35, has also held gold at super-welterweight, middleweight, and light-heavyweight.
When Crawford boxes Canelo in September, the American will be hitting a career-high weight.
