Israel Adesanya and Robert Whittaker are back in the octagon together on February 12 for UFC 271.
The pair first met one another in Melbourne at UFC 243 back in October 2019.
Adesanya won on the night via a second-round knockout, unifying the UFC Middleweight Championship in the process.
Between then and now, Adesanya has retained his belt on three occasions with his most recent defence coming against the Italian Marvin Vettori at UFC 263.
At UFC 259, he also took the step up to Light Heavyweight where he was beaten by unanimous decision against Polish MMA artist Jan Blachowicz.
Whittaker, meanwhile, has three victories to his name in the time since. His UFC on ESPN fight against Kelvin Gastelum was awarded Fight of the Night.
