Liverpool boxer and British WBA world super-middleweight champion Callum Smith will fight Saul 'Canelo' Alvarez on 19 December in the United States of America.
Smith remains unbeaten after 27 fights and has defended his world title twice since defeating George Groves in 2018.
"I have wanted a big fight since becoming world champion, so I am pleased that during these challenging times we can deliver to the fans a fight between the very best in the division," Smith said.
"I truly believe I [will] beat him and will prove that 168lbs is my division."
Alvarez, 30, has lost just one of his 56 fights to Floyd Mayweather in 2013.
"I'm very happy to return to the ring and continue to make history," Alvarez added.
"I am motivated to continue to be the best, and I look forward to fighting Callum Smith, who is one of the best at 168lbs."
Alvarez beat Smith's brother Liam in Texas in 2016 in a ninth-round knockout.
