Mixed martial arts fans spent much of the night, and lots of their hard-earned cash, in anticipation of the weekend's UFC featherweight title bout - only for Irishman Conor McGregor to knock out his opponent Jose Aldo in just 13 seconds.
McGregor pounced on the Brazilian by turning his opponent's righthand lead into a smooth left finisher to the jaw, throwing him cold to the canvas.
The Las Vegas match took place at 5 am UK time, meaning many British fans spent the early hours building excitement for the bout.

And for avid MMA fans, the anticipation meant that McGregor's impressive speed served as a somewhat expensive anti-climax.
โNo power, just precision," McGregor told reporters following the fight.
โNo speed, just timing. Thatโs all it takes. These are four-ounce gloves. Thatโs all it takes.โ
