Kamaru Usman has moved up a weight class in search of joining the group of double champions in the Ultimate Fighting Championship. However, despite his victorious career, the Nigerian arrives as a big underdog for the duel. The former champion faces Dricus du Plessis in the main event of UFC Oklahoma , this Saturday (18). According to bookmakers, the 'Nigerian Nightmare' has little chance of surprising the current middleweight champion (up to 83,9 kg).
According to Stake , Usman is the underdog in the match. A victory for the Nigerian pays 2,88 for every real bet, meaning a R$100 bet would yield R$288 if he wins. On the other hand, someone investing the same amount on Du Plessis would receive R$142 if the South African wins.
