I didn't see the punch until I slowed the video down to 0.25. Jesus! That punch was scarily fast. I feel a bit bad for Bellew now
UFC champion Conor McGregor moved closer to a possible fight with five-weight world champion Floyd Mayweather by securing a boxing licence.
The Irish fighter became the Ultimate Fighting Championship's first dual division champion in November.
McGregor, 28, has said he wants $100m (£80m) to meet Mayweather, who has played down the prospects of a fight.
The licence has been granted by the California State Athletic Commission, allowing him to box in the US state.
McGregor's trainer John Kavanagh has said he would "put a few quid" on a bout with the retired Mayweather, 39, taking place next year.
Never gonna happen. All just a giant publicity stunt for both men.
Any top domestic fighter would beat McGregor in a boxing match let alone Mayweather! That's no slight on McGregor he's an MMA fighter not a boxer, it's apples and oranges.
Dana White isn't going to let his golden goose go get humiliated stepping in a boxing ring with Mayweather.
I can't help but like him.
Haye does love the sound of his own voice.
I'll never get past the "broken toe"/Klitschko fight.
