Conor McGregor will do what very few thought was never going to happen in the early hours of Sunday morning.
The Notorious will step into the boxing ring for the first time as a professional, as he tries to claim the huge scalp of the undefeated Floyd Mayweather.
The Dubliner has been gunning for a fight with the five weight world champion, and is set to make around $100m as a result of the bout in Las Vegas.
McGregor hasn't been quietly confident he can defeat the now-40 year old Mayweather, rather he's been very loud about his chances of knocking him out.
We saw throughout the tour that he reckons he can take out Mayweather within 4 rounds, while another prediction from the man labelled 'Mystic Mac' sees him beating the 49-0 boxer inside 2.
A tweet published earlier seems to suggest that he's not backing down:
Wake up Floyd. It's all over.— Conor McGregor (@TheNotoriousMMA)
There's no doubt in his mind who will win the fight, despite most believing he hasn't a chance.
