Conor McGregor enjoyed Saturday's UFC action with his son Conor Jr.
The Notorious uploaded a snap on Instagram as he thanked the fighters involved in the show "for the entertainment".
He posted: "Me and Jr. watching last nights fights. Thanks for the entertainment lads and ladies!"
Khabib Nurmagomedov defeated Justin Gaethje in the main event at UFC 254 in Abu Dhabi before breaking down in the Octagon after the fight.
An emotional Nurmagomedov, whose father died earlier this year, then revealed he would not be fighting again.
He said: "Today I want to say this is my last fight. No way am I coming here without my father. When UFC comes to me about Justin I spoke with my mother for three days. She didn't want me to fight without father. And I said this is my last fight and I have given her my word.
"There is only one thing I want from UFC, to put me as No 1 pound-for-pound fighter in UFC, greatest in world. I think I deserve. I want to say thank you Dana, Fertita brothers.
"Thank you so much Justin. I know you are great, I know how you take care of your people. Be close with your parents, because you never know what is going to happen tomorrow. Thank you coach, thank you guys. Today is my last fight in the UFC.
"It was my father's dream. Dustin [Poirier] and Conor [McGregor] will fight in January, I have choked both out, I am not interested in this."
McGregor paid respect to his rival after the announcement, tweeting: "Good performance @TeamKhabib. I will carry on. Respect and condolences on your father again also. To you and family. Yours sincerely, The McGregors."
