Nate Diaz names one aspect of first Conor McGregor fight that changed UFC history forever

Boxing legend disgusted after Conor McGregor spat on Khabib Nurmagomedov fan

However, it was the first fight against McGregor that Diaz fondly remembers, a second-round rear-naked choke to halt McGregor's then-undefeated UFC run just three months after winning the UFC Featherweight Championship against then-champion Jose Aldo.

Diaz Relives Iconic Slap

While many MMA fans remember the short-notice buildup to McGregor-Diaz 1, few are likely to recall Diaz's fight-altering slap to frustrate the Irishman.

This ultimately led to the eventual upset, giving Diaz, a winner of The Ultimate Fighter Season 5, a new sense of celebrity fame. Of course, McGregor would get the better of the Stockton, CA native five months later by majority decision at UFC 202. Still, Diaz uncovered why his coveted slap on McGregor sticks out when reflecting about his career.

"When he was hitting me and running. and s*** and I smacked him," Diaz said in an interview with Full Violence. And then I was like, 'Aha, b****....you just got slapped. That was funny. A lot of times, it's not intentional."

Diaz said he'd be interested in returning to the UFC, but there aren't any intriguing matchups that would make the former UFC lightweight title challenger get back into the deep end.
