But even that wasn’t enough for him, as in 2017, McGregor entered the boxing ring to fight the freaking legend – Floyd Mayweather! Despite being inexperienced in professional boxing, McGregor put up a valiant effort, but ultimately, Mayweather mopped the floor with him (but not really) and won the fight via TKO in the 10th round.

After that crushing defeat, Conor’s career was like a bad rollercoaster going up, down, and sideways, including a series of announcements about retiring and eventual comebacks, as well as personal controversies and legal issues. What definitely didn’t help him was the 2018 fight against Khabib Nurmagomedov that ended in defeat via submission and cost Conor his Lightweight belt as well as his pride. So is this it? Career over, right?
