Vettori gets his shot thanks in large part to consensus No 1 contender Robert Whittaker wanting a longer turnaround between bouts after his unanimous decision win over Kelvin Gastelum last weekend. Whittaker lost the title to Adesanya in 2019 in front of a record crowd of more than 57,000 people in Melbourne, and has won three bouts against top 10 opponents since then. UFC president Dana White told ESPN Whittaker would likely get a title shot later in the year.
Vettori (17-4) comes into the bout off wins over No 10 ranked Kevin Holland, who took the bout on short notice when Darren Till (No 6) was forced out with an injury, and Jack Hermansson (then ranked No 4).
Fellow Kiwi Brad Riddell, Adesanya's teammate from Auckland City Kickboxing, will also fight on the June card - with a tantilising clash of strikers against Drew Dober.
Riddell (9-1) was supposed to fight lightweight No 15 Gregor Gillespie in late March, however was forced to withdraw from the fight on the day of the event after members of his support team tested positive for Covid-19. Riddell did not catch the virus.
With Gillespie since booked, Riddell gets a match-up to please the fans. Like Riddell, Dober (23-10) is of a striking background and does his best work on his feet. Both fighters have shown potential to make a run up the rankings, though Dober hit a road block in his last bout against Russian grappling powerhouse Islam Makhachev.
