Decade Anniversary: When UFC Fighter Pulled Off Sport's Greatest Upset
By 813 Staff
Combat sports fans will spend the next few weeks reflecting on one of mixed martial arts' most seismic upsets as the ten-year anniversary of Nate Diaz's stunning victory arrives this week. Home of Fight (@Home_of_Fight) marked the milestone on social media, reminding followers that a decade has passed since the Stockton fighter delivered what many still consider the sport's most shocking result.
League sources confirm the anniversary refers to Diaz's March 2016 triumph over Conor McGregor at UFC 196, a bout that fundamentally altered the trajectory of both fighters' careers and reshaped how the promotion approached matchmaking at the highest level. Those close to the situation say the fight, which Diaz won by second-round submission, came together on just eleven days' notice after McGregor's original opponent withdrew due to injury.
The front office had been quietly confident that McGregor, then riding an unprecedented wave of momentum after claiming the featherweight championship, would steamroll through a replacement opponent on short notice. Instead, Diaz absorbed the Irish fighter's best shots, bloodied him on the feet, and forced a tap via rear-naked choke in front of a stunned Las Vegas crowd.
What made the result so jarring wasn't just the outcome but the manner of victory. McGregor had appeared invincible in his UFC run, finishing opponents with surgical precision while building a persona that transcended the sport. Diaz, accepting the fight while vacationing in Cabo, stepped in as a significant underdog and delivered a performance that instantly became part of combat sports folklore.
The ripple effects extended far beyond that night. The upset forced an immediate rematch five months later, which McGregor narrowly won by decision, and established Diaz as one of the sport's most bankable stars despite a relatively modest winning record. Industry insiders point to that upset as the moment when the promotion fully committed to entertainment value and star power over traditional rankings and title contention.
A decade later, both fighters remain relevant figures in combat sports conversations, though neither currently competes in the UFC. McGregor has fought sparingly in recent years while pursuing business ventures, and Diaz departed the promotion in 2022 to explore boxing opportunities. The anniversary serves as a reminder that in combat sports, reputation means nothing once the cage door closes, and any fighter on any given night can deliver a result that reverberates for years to come.
