Conor McGregor vs Floyd Mayweather Highlights & KO | The Money Fight Rewind

Video: Watch full highlights and the knockout finish from Conor McGregor vs Floyd Mayweather — the historic 2017 crossover bout that brought UFC and boxing head-to-head in Las Vegas.

On August 26, 2017, two combat sports worlds collided as Conor McGregor, the biggest name in UFC, faced boxing legend Floyd Mayweather in the blockbuster crossover known as “The Money Fight.” It wasn’t just spectacle — it was a pivotal moment in MMA and boxing history.

McGregor entered the ring fresh off his UFC 205 win over Eddie Alvarez, making him the first UFC double champion. Despite having no pro boxing matches, he battled Mayweather — 49-0 at the time — for ten entertaining rounds. His footwork, striking variety, and showmanship stunned doubters and energized the MMA world.

For fans who watched McGregor’s rise from Cage Warriors to UFC 229 and the wild Khabib fight, this night felt like a surreal high point. Mayweather earned the TKO in Round 10, but McGregor’s performance proved UFC stars could command boxing’s biggest stages.

Whether you're reliving it or watching for the first time, this era is a historic benchmark in the careers of McGregor, Khabib, and Alvarez — and a defining moment in the global growth of MMA.
