When Conor McGregor dismissed the loss against Khabib Nurmagomedov - "I only count knockouts"

Khabib Nurmagomedov vs. Conor McGregor is considered one of the greatest rivalries in UFC history. At UFC 229, Nurmagomedov defeated McGregor by fourth-round submission, and the rematch never materialized.

Two years later, McGregor experienced the first knockout loss of his career against Dustin Poirier at UFC 257. As he prepared for the UFC 264 trilogy fight against Poirier, McGregor mentioned that he only views knockouts as conclusive endings to a fight, implying that he did not count his loss against Khabib as a true defeat. McGregor said to Stephen A. Smith of ESPN MMA:

"My record in mixed martial arts competitions is 19 wins and one loss. I only count knockouts. Dustin's record is 13 wins and two losses. The only thing that is definitive in this business is a knockout. All the other stuff - the decisions, the points - it all means nothing to me."
