Usman vs Edwards preview and predictions
Could an upset be on the cards on Saturday?
Leon Edwards has had to wait seven years to get his chance of revenge, and is a now a very different prospect to the fighter that lost to an unanimous decision to Kamaru Usman in Florida back in 2015.
The British fighter has honed a superb takedown defence in the intervening years which could nullify Usman's main weapon.
Couple that with his impressive striking ability, and it could add up to a new 170-pound champ being crowned on Saturday night.
Who is Kamaru Usman?
Having chalked up 19 straight MMA victories, Kamaru Usman is one of MMA's best grapplers and took the welterweight crown from Tyron Woodley in 2019 at UFC 235.
While the "Nigerian Nightmare” is known for his floor work, he can punch his way out of trouble when needed, and perfectly illustrated his fists as a means of attack in knockout wins against the likes of Colby Covington, Gilbert Burns and Jorge Masvidal.
Who is Leon Edwards?
Jamaican-born British star Leon Edwards escaped a world of gang violence in Birmingham thanks to MMA.
Making his professional debut at 19, Edwards would eventually sign up with the UFC four years later.
He has since gone on to chalk up 11 wins from 14 fights and a victory on Saturday would see him become Britain's first champion since Michael Bisping in 2016.
Usman vs Edwards latest odds: who is the favorite to win?
Defending champ Usman is once again the favorite for this rematch, coming in at 1/5 with the majority of bookies, with Edwards marked out at 3/1 to end the Nigerian Nightmare's 19-fight unbeaten streak.
Usman vs Edwards: recent results
Usman's last title defence came back in November at UFC 268 with his rematch fight with Colby Covington ending in a unanimous points win for the Nigerian Nightmare after Usman had dropped the challenger twice in quick succession at the end of the second round.
Edwards' last appearance in the Octagon came at UFC 263 in June last year, with the British fighter claiming a clear points win over Nate Diaz after dominating the first four rounds and most of the fifth.
UFC 278 full card and highlights
Beyond the much anticipated headline act rematch, UFC 278's co-main event sees the return of former middleweight champ Luke Rockhold in a tasty match up with Paulo Costa.
