The UFC Middleweight and Interim Middleweight Championship will be unified on October 5th, when Robert Whittaker takes on Israel Adesanya at UFC 243. Set to take place in Australia, it will be the third time within a year that the promotion held an event within the country.

The fight was formally announced on Friday at one of UFC’s quarterly press conferences, previewing many of the big upcoming fights. The press conference was hosted by Dana White and was in the T-Mobile Arena in Las Vegas, Nevada.

“He’s fought twice in the last maybe three years. I’ve been busy,” said Adesanya when comparing himself to Whittaker. The Aussie defended himself, saying “It’s just one of those things, I got sick and you can’t help that.” Adesanya responded to that by claiming he fought through a knee injury in his last appearance.

Israel Adesanya has had an electric year and a half, defeating top contenders in Derek Brunson, Anderson Silva and Kelvin Gastelum. Robert Whittaker’s last fight was at UFC 225, where he got his first Championship defence over Yoel Romero.

The press conference featured other big names in the UFC like Daniel Cormeir, Stipe Miocic, Khabib Nurmagomedov, Dustin Poirier, Max Holloway and Frankie Edgar.
