Floyd Mayweather Jr picked up the 50th win of his illustrious career, defeating Conor McGregor by 10th-round TKO on Saturday night in Las Vegas' T-Mobile Arena.
With the victory, Mayweather surpasses Rocky Marciano, who retired in 1956 with a 49-0 record.
Many expected Mayweather to beat McGregor, with the biggest question being whether the fight would last the full 12 rounds. Mayweather's last knockout was against Victor Ortiz in 2011.
No sellout but Mayweather, McGregor have Sin City buzzing
Although McGregor is UFC's lightweight champion, he was clearly overmatched against somebody who's one of the best defensive boxers in history.
The likes of Manny Pacquiao, Canelo Alvarez, Miguel Cotto and Oscar De La Hoya have all tried to take down Mayweather and failed. McGregor stood little chance in what was his boxing debut.
