Conor McGregor, the former two-division UFC champion, weighed in on social media about the weigh-in controversy surrounding Khamzat Chimaev from Chechnya, who hails from Sweden, ahead of the UFC 279 clash with Nate Diaz. The comments came as UFC president Dana White announced adjustments to the event lineup. McGregor questioned the integrity of the card and the implications of the weigh-in issues for the sport, suggesting a course of action if a fighter fails to meet the mark. His stance reflected a broader debate in the MMA community about weigh-ins, health, and fair competition, and how those elements influence matchups and marketability on fight night.
