WATCH: Khabib Nurmagomedov makes it 29-0 with UFC 254 win... then retires

Khabib Nurmagomedov was unstoppable at UFC 254, the lightweight champion extending his unbeaten record to 29-0 with a crushing second round win over Justin Gaethje.

But even more shocking than the triangle choke the champ used to close out the fight were the scenes after it, an emotional Nurmagomedov announcing that the fight would be his last.

The 32-year old paying tribute to his late father and lifelong coach Abdulmanap, who passed away in July. It was his first fight since the tragic loss.
