Conor McGregor is on the hunt for another record.

Already the first fighter to hold simultaneous world titles in two separate weight divisions and the only fighter to hold knockout wins in the featherweight, lightweight and welterweight divisions of the UFC, McGregor has his eyes on another achievement: the all-time UFC knockout record.

On Saturday night in Charlotte, ‘The Immortal’ Matt Brown scored a sensational one-punch KO of fellow veteran fighter Court McGee as the 42-year-old UFC veteran notched up his 13th knockout win for the promotion in a UFC career which dates back to June of 2008. The finish tied Brown with ‘The Black Beast’ Derrick Lewis at the summit for the most knockout finishes by any fighter in UFC history.

But as he expressed on social media in the hours after the fight, this is an achievement that Conor McGregor has his eyes on.

Matt Brown, at 42 years of age, now holds the joint highest KO’s inside the UFC with 13KO’s. Him and “The Beast” Lewis are tied. I hold 8 KO’s inside the UFC currently, at 34 years of age.
I’m getting this record.

“Matt Brown, at 42 years of age, now holds the joint highest KO’s inside the UFC with 13KO’s,” McGregor tweeted. “Him and ‘The Beast’ Lewis are tied. I hold 8 KO’s inside the UFC currently, at 34 years of age. I’m getting this record.” Brown later referenced this with a tweet of his own, responding to McGregor: “I’ll fight you for it.”

The Dubliner has scored some of the most memorable knockouts in UFC history, such as his dramatic second-round finish of Chad Mendes at UFC 189, or his 13-second demolition of Jose Aldo in late 2015. His finishes of Eddie Alvarez to claim the UFC light heavyweight title, and the shoulder-strike lead-in to his head kick (and strikes) win against Donald Cerrone also stands out.

McGregor is expected to get an opportunity to increase his KO tally to nine later this year when he fights fellow ‘The Ultimate Fighter’ coach Michael Chandler is a fight expected to be the year’s biggest combat sports pay-per-view event.
