Reigning middleweight champion, Israel Adesanya will make the third defense of his title in the rematch against Marvin Vettori on June 12.
The pair battle it out in the headliner of UFC 263 live on pay-per-view.
But the organizers are yet to determine the venue that will accommodate the event.
The contest became official earlier today during the UFC 261 fight between Kamaru Usman and Jorge Masvidal.
Adesanya (20-1) defeated Vettori (17-4-1) by split decision after three rounds in April 2018.
In his previous outing in March, he went up a weight class to challenge the reigning light heavyweight champion, Jan Blachowicz.
But the Nigerian fell short dropping a unanimous decision. In September 2020, Adesanya knocked out Paulo Costa in the second round.
And that was following a unanimous decision against Yoel Romero which he secured in March of the same year.
The Nigeria-born representative of New Zealand claimed the belt against former champion, Robert Whittaker by knockout in the second round in October 2019.
Vettori hasn’t lost since his defeat to Adesanya and has scored five straight victories.
In his most recent appearance inside the Octagon earlier this month, he defeated Kevin Holland by unanimous decision.
In December last year, he similarly defeated Jack Hermansson and knocked out Karl Roberson in the first round in June.
