Khabib Nurmagomedov leaves UFC as the undisputed lightweight champion following his victory over Justin Gaethje.
The Eagle almost immediately upstaged his own exploits by confirming his retirement in his post-match interview.
A triangle choke had overcome Gaethje and as it turned out, that would be Khabib's last action in the Octagon.
It's astonishing to think there were concerns about his fitness going into the clash, not least because of his dramatic weight change in the days preceding it.
Dana White also confirmed he had fought Gaethje with three broken bones in his foot.
However, the emotional scenes after the fight spoke not only of the 32-year-old exiting a sport in which he is now seriously being considered among the greatest of all time.
It's been a deeply troubling year for Khabib, who lost his father and trainer in July.
Abdulmanap Nurmagomedov passed away earlier this year due to coronavirus complications after a series of health problems.
It was no surprise then, that his son paid tribute with his first Instagram post since the Gaethje fight.
"When ALLAH [is] with you, nobody can broke you, nobody," he wrote.
"Thanks Father for everything, you teach all my life, may ALLAH grant you the highest Paradise."
Addressing Gaethje after the fight, he also addressed the loss of his father and praised the American, whose one request ahead of their encounter was that his parents could be present.
"Be close with your parents. You never know what will happen tomorrow," he said live on BT Sport.
It's a real tragedy that Abdulmanap couldn't be there to see his son hit 29-0. Everyone saw what it meant to him a year ago when Khabib beat Dustin Poirier.
That relationship has been central to the lightweight's career.
Khabib confirmed he was retiring because of a promise he had made to his mother.
So while it's UFC's loss, it's only natural that he's putting family first.
