Conor McGregor—in no uncertain terms—is not a fan of Johnny Eblen.

During this past Saturday’s PFL Battle of the Giants event, McGregor spent much of his time on social media roasting the action on the main card. With the exception of the main event, which saw Francis Ngannou score an impressive knockout in his MMA return, four of the top five fights on the lineup went to the scorecards and one fight in particular drew McGregor’s ire.

Eblen successfully defended his middleweight title in a rematch with Fabian Edwards, but the five-round decision victory had McGregor mocking the champion’s workmanlike effort. On Tuesday, Eblen tweeted a critique of McGregor, which the UFC star has since responded to.

“Conor went from ‘The face of the fight game’ to ‘The disgrace of the fight game,’ Eblen wrote on social media. “He embodies literally everything I don’t want to be as a man or as a human. What an embarrassment. It’s giving Icarus.”

To that, McGregor responded, “Bro the fight was absolute poo, that’s it.”

Eblen currently sports a 16-0 record and has made a name for himself as the best middleweight in the world outside of the UFC. He entered Battle of the Giants holding the No. 5 spot at 185 pounds in the MMA Fighting Global Rankings.

His criticism of McGregor stems from the former two-division champion’s lack of success and inactivity in recent years. “Notorious” has just one win in the past eight years, with Khabib Nurmagomedov, Dustin Poirier, and boxing legend Floyd Mayweather Jr. all handing him defeats.

McGregor has had plenty of time to engage in public feuds as he awaits his first fight since July 2021, when he broke his leg in a fight against Poirier at UFC 264. The 36-year-old was to make his comeback against rival Michael Chandler at UFC this past June, but was forced to withdraw due to injury.
