Conor McGregor Denies Using 'Mind Altering Substances' Before UFC 329 Loss

Conor McGregor's highly anticipated return to the Octagon ended in a disappointing 69-second loss to Max Holloway in the main event of UFC 329 on Saturday.

What happened?

McGregor took to social media to deny the notion that he used any "mind altering substances" before the fight, despite his poor performance. In a now-deleted tweet, he claimed that he was in peak shape when he entered the Octagon. However, his actions on the night of the fight told a different story.

What comes next?
