Khabib Nurmagomedov extended his professional record to a perfect 29-0 with a second-round submission victory over Justin Gaethje at UFC 254.
But perhaps the biggest news on the MMA calendar came when he subsequently announced his retirement from the sport.
The 32-year-old Russian, who was fighting for the first time since his father’s death this summer, put on a superb display to finish interim UFC champion Gaethje with a triangular choke and retain his lightweight title.
After his victory, Nurmagomedov announced his retirement from the sport in a touching interview after the fight in the octagon at “Fight Island”.
He said, “Thanks for those guys, these guys with me, have been with my dad for over 10 years.
“My whole team, AKA with coach Javier [Mendez], I love him so much, my whole team. Today, I mean, was my last fight.
“I’m not going to come here without my father. It was the first time, after what happened with my dad, when the UFC called me about Justin.
“I speak with my mother for three days, she doesn’t want me to go and fight without a father. I promised him this would be my last fight, and if I give my word, I must follow it. It was my last fight here.
“I only know one thing I want from the UFC, you have to be me on the No. 1 pound-for-pound fighter in the world, because I deserve it. Undisputed and undefeated UFC lightweight champion, 13-0, 13 in UFC, 29 in professional MMA career. I think I deserve it.
“One more thing, I want to say thank you Lorenzo Fertitta, thank you Dana, Hunter, all guys. Thank you very much, and of course I don’t forget Joe Silva who signed me here to the UFC. Joe Silva, thank you.
“This whole UFC team, everyone in the world, this whole pandemic, they’re putting on a great show. Thanks so much Justin. Justin, 2016 I remember when I lost weight you helped me a lot. Thank you brother. I know you are a great man, I know how you take care of your people.
“I know a lot about you, because of your parents, because someday something is going to happen. You never know what’s going to happen tomorrow, you never know.
“Today is my last fight here at the UFC. It was my father’s dream. Dustin and Conor are going to fight in January, I’m choking them both. I do not care.
