A five-week stay for the UFC on Fight Island kicks off in earnest on Saturday with UFC 253 from Yas Island, Abu Dhabi. The main event will feature undefeated middleweight champion Israel Adesanya (19-0) looking to defend his title for the second time against an undefeated challenger in Paulo Costa (13-0).
It is only the second title fight in UFC history that will feature two unblemished records. It will also feature two men who genuinely dislike each other. The fight was supposed to take place earlier this year, but Costa underwent biceps surgery.
