Khabib Nurmagomedov admits Archie Colgan is Usman Nurmagomedov’s ‘toughest’ test

Khabib Nurmagomedov has identified Archie Colgan as the toughest challenge yet for his cousin Usman Nurmagomedov's PFL lightweight title reign. The pair will clash in the main event of PFL New York on July 31 at UBS Arena in Long Island, with Usman's crown on the line.

The undefeated Colgan (13-0), a former Division 1 collegiate wrestler, brings a wrestling-heavy skillset that Khabib acknowledges poses a legitimate threat to Usman's ground control. Colgan's résumé includes notable victories over Manuel Sousa, Mansour Barnaoui, and Jay-Jay Wilson. Despite recognizing the challenge, Khabib expressed confidence in his cousin's preparation. "I think this is the toughest fight for Usman," Khabib told Anatomy of a Fighter. "This guy's a real deal. He knows how to wrestle. He's tough, never lost. Of course, Usman is in incredible shape -- physically, mentally, everything is there. I think this is a very-very high-level fight."

Usman (21-0) has already defended his title twice since capturing it last year against Paul Hughes. This matchup carries significant weight beyond the immediate title defense—it marks the final bout of Usman's current PFL contract, making the outcome crucial for his future with the promotion. Adding another layer, UFC lightweight champion Justin Gaethje, a former opponent of Khabib, will be cornering Colgan at the event.

The lightweight title fight broadcasts Friday, July 31 at 7 p.m. ET on ESPN.
