Conor McGregor’s Double-Champ Takeover
On November 12, 2016, Conor McGregor stopped Eddie Alvarez in the second round at UFC 205 in New York, becoming the first fighter to hold two UFC championships simultaneously. The reigning featherweight champion added the lightweight belt at Madison Square Garden, turning his bold promises into a milestone that reshaped the promotion’s championship story.
Early career in Dublin and Cage Warriors
Born in Crumlin, Dublin, McGregor began his professional MMA career in 2008. Before joining the UFC, he won Cage Warriors titles at featherweight and lightweight, becoming a two-division champion in the promotion. The UFC athlete profile lists both Cage Warriors titles and his UFC championship history.
UFC rise and two-division titles
McGregor made his UFC debut in April 2013. In December 2015, he knocked out longtime featherweight champion José Aldo in 13 seconds at UFC 194. The following year, he defeated Eddie Alvarez at UFC 205 to win the lightweight title and become the first simultaneous two-division UFC champion. The UFC’s career retrospective covers both title wins.
Rivalries and crossover boxing
McGregor’s two-fight series with Nate Diaz became one of the UFC’s defining rivalries of the 2010s: Diaz submitted McGregor at UFC 196, and McGregor won their rematch by majority decision at UFC 202. In August 2017, McGregor also faced undefeated boxing champion Floyd Mayweather in a professional boxing match. Mayweather won by tenth-round TKO. The bout broadened McGregor’s profile beyond MMA; see our Mayweather career feature.
Business ventures and setbacks
In 2018, McGregor launched Proper No. Twelve Irish whiskey, adding a business venture to his public profile. Inside the Octagon, he suffered a serious leg injury in his July 2021 bout with Dustin Poirier at UFC 264. These milestones show how his career extended beyond championship fights while continuing to face setbacks.
Conor McGregor’s legacy
McGregor’s fast rise, precise counterstriking, two UFC titles, and crossover appeal made him a major figure in modern MMA. His championship run and high-profile bouts helped bring new audiences to the sport, while his record also includes difficult losses and interruptions.
The results behind the double-champion moment
McGregor won the undisputed featherweight title by knocking José Aldo out in 13 seconds at UFC 194 on December 12, 2015. His 2016 rivalry with Nate Diaz then exposed a different challenge: Diaz submitted him in their first meeting, while McGregor won the five-round rematch by majority decision. The Alvarez victory completed that eventful year with a second-round TKO and a second UFC championship.
