Conor McGregor's UFC 329 injury fuels MGK social media feud

Conor McGregor returned to the UFC at UFC 329 in Las Vegas, facing Max Holloway. The bout ended after 69 seconds when McGregor suffered a knee injury, prompting him to announce plans for surgery and a future comeback.

Music artist Machine Gun Kelly (MGK) used Instagram to mock McGregor's injury, reposting photos from their 2021 MTV Video Music Awards altercation and posting captions such as “Knees weak of old age, the real Conor can’t stand up.” MGK reiterated the insults in a follow‑up video, referencing the earlier VMA incident and criticizing the short fight duration. McGregor responded on X, describing the injury as severe and denying rumors of being unprepared for the fight.
