The backstory and the clear dislike the two fighters had for each other made this fight a must-see. 'Notorious' was coming off a lucrative boxing match against Floyd Mayweather, and Nurmagomedov had just won the championship.
The build-up leading up to the fight was grim and toxic. After conducting the press conference, Dana White said that this was the darkest press conference he had ever handled. The pressure was on 'The Eagle' to win as McGregor accused him of never facing elite competition.
As soon as the bell rang, Nurmagomedov took control. He dominated McGregor in the grappling exchanges and even on the feet. The most shocking moment of the fight came when 'The Eagle' dropped McGregor in the second round with an overhand right. The Dagestani went on to submit the Irishman in the fourth round.
#1. Francis Ngannou vs. Ciryl Gane at UFC 270:
Francis Ngannou became the heavyweight champion in March 2021 when he finished Stipe Miocic by knockout. After winning, Ngannou left for his native country Cameroon to celebrate with his people, which brought a delay in negotiations for his next fight.
The matchmakers were left frustrated, and they made an interim heavyweight title fight between Ciryl Gane and Derick Lewis. This made Ngannou feel disrespected as he was ready to defend in September, and the interim title bout was made for August.
'Bon Gamin' beat Derick Lewis by TKO in the third round, setting up an epic title unification fight between the two former training partners. Ngannou went public before the fight about his pay and said he wouldn't sign a new UFC contract on the pay he was currently on.
This made the fight a must-win for 'The Predator' as he would have an advantage in his ongoing negotiations. To no surprise, the fight began with Gane taking control of the center of the octagon and beating Ngannou to the punch.
However, in the third round, 'The Predator' took Gane down and controlled him there. Ngannou won the bout via UD and revealed after the fight that he suffered a torn ACL and a damaged MCL in training camp. This made his win even more special, given the incredibly high-pressure circumstances.
