Alex Pereira shook up the middleweight division on Saturday when he knocked out long-reigning champion Israel Adesanya. ‘Poatan’ seemed to many to be losing going into the fifth round of the fight, but the MMA Gods had other plans.

Costa will present a fears test for Whittaker though, the Brazilian always brings it whatever fright he may be in and is coming off a win over former title holder, Luke Rockhold.
