Saul 'Canelo' Alvarez has finally confirmed his opponent.
Boxing's biggest name has agreed on a unification showdown against Caleb Plant and the pair will collide on November 6.
The bout will be on FOX PPV under Al Haymon's PBC Promotions alongside Canelo Promotions.
The confirmation by Canelo finally puts to bed the rumours of who he will face next after an ongoing saga with money being the stumbling block in previous weeks.
Las Vegas is the location and all four major world titles at super middleweight (WBA, WBC, IBF and WBO) are on the line for the first time.
"I am very excited to have this fight before me. I am happy because I am going to make history, and in my career that's exactly what I want to do - leave my mark in boxing," Alvarez said in a statement released on Thursday.
"I can't wait to see all my fans on November 6."
September 18 was the original date scheduled for the undisputed clash and following unsuccessful negotiations, Canelo contemplated taking on light heavyweight titlist Dmitry Bivol.
"The project since we got to 168 was this: to be the first Latino and Mexican to be undisputed. It is something that I have been projecting for more than one year," Alvarez's trainer Eddie Reynoso told ESPN.
"It is the advantage of being a free agent and having an excellent relationship with all the promoters; you can negotiate any fight and this benefits boxing.
"I am very happy because we are doing a great job in sports as a coach and administrative as a manager. We are going to work hard to win and continue to write history in Mexican and world boxing!"
Canelo will return for the first time since shattering Billy Joe Saunders' orbital bone on Cinco de Mayo weekend. His ninth-round stoppage saw him add the WBO strap to his WBA and WBC belts.
Plant's IBF crown is the only title to elude him at 168lbs. Nashville's Plant is undefeated from 21 fights and has made three defences of his red-and-gold title.
Canelo will fight on FOX, a new territory for the Mexican having defeated Rocky Fielding, Daniel Jacobs, Sergey Kovalev, Callum Smith, Avni Yildirim and Saunders on DAZN since 2018.
The 31-year-old is a four-division world champion and has not tasted defeat since 2013 to Floyd Mayweather.
While it means Eddie Hearn - who has promoted Canelo's previous three bouts - won't be involved in the event as the promoter, it is expected he'll be present to represent the superstar on the behalf of Canelo Promotions.
