UFC Rankings Update: Kamaru Usman falls to No.4 on P4P list, Merab Dvalishvili ranked No.3 as Jose Aldo drops to No.6 at bantamweight

This week's UFC rankings update has seen major changes amongst the men's pound-for-pound list following UFC 278's stunning main-event between Leon Edwards and Kamaru Usman.

'Rocky' and 'The Nigerian Nighmare' stepped into the octagon for their highly anticipated rematch but this time, the welterweight title was on the line. Usman was one win away from tying Anderson Silva's record of consecutive UFC victories (16) whereas Edwards was challenging for UFC gold for the first time.

What followed was one of the most shocking moments in MMA history. After losing the first round to Edwards, Usman returned to his clinical wrestling style and dominated for three rounds. Heading into the fifth, 3-1 down on the scorecards and with only a minute left, 'Rocky' caught the 35-year-old with a headkick that laid him out flat.

British fight fans have their second UFC champion and his name is Leon Edwards.

The victory for Edwards moved the 30-year-old to No.6 in the men's P4P list for the first time. Usman's first loss in the UFC has dropped him from No.1 to No.4 and given Alexander Volkanovski the No.1 spot. Israel Adesanya and Charles Oliveira each climbed one place to No.2 and No.3 respectively.

The shake-up in the P4P list has meant Robert Whittaker drops out of the rankings entirely due to every fighter below Edwards falling one place.

The 170lb division sees its new champion Leon Edwards crowned at the top as Kamaru Usman drops to the No.1 welterweight in the rankings. Usman's loss means Colby Covington is now at the No.2 spot in the division. Geoff Neal's recent victory over Vicente Luque was rewarded as the American moved two places to No.6, dropping Stephen Thompson, Sean Brady and Luque all down one spot each.

Rose Namajunas and Weili Zhang have fallen to No.5 and No.6 and Taila Santos was rewarded for her impressive performance against Valentina Shevchenko earlier this year. The Brazilian is now No.12, swapping places with Yan Xiaonan.
