It feels like an eternity since we saw one of the sport's most entertaining champions showcase his skills inside the Octagon but, following victory over Yoel Romero in March, Israel Adesanya returns at UFC 253 to face another terrifying opponent in defence of his 185lb crown.

Paulo Costa is the man hoping to dethrone the Kiwi striker, arriving to the cage with a perfect 13-fight record complete with 11 pulversising stoppages along the way.

Can the Brazilian inflict Adesanya's first defeat in 19 fights - or will The Last Stylebender further elevate his soaring stock?

Elsewhere, a new light heavyweight champion will be crowned following Jon Jones' decision to vacate the 205lb title as Dominick Reyes and Jan Blachowicz go toe-to-toe in search of UFC gold.

And highly-rated featherweight Hakeem Dawodu returns to action in a must-see clash against Zubaira Tukhugov in the pick of the fights on the rest of the main card.
