Conor McGregor is back in the octagon for the first time in over a year this weekend to face Dustin Poirier.
The Notorious was last seen in action last January when he destroyed Donald Cerrone in just 40 seconds.
He defeated Poirier in a featherweight bout back in 2014, but the American has had plenty of success at lightweight since.
The build-up to this bout has been a lot quieter than many of McGregor's fights, but there should be fireworks in the octagon.
Here's what you need to know:
Where is the fight?
The bout takes place at Yas Island in Abu Dhabi.
When is it?
The event begins late on Saturday night and continues well into the early hours of Sunday morning.
What time is McGregor fighting at?
The main event should start at around 5am Irish time.
It's a busy card, with the early preliminary fights starting at midnight before the pre-lims kick-off at 1am.
The main card is scheduled to begin at 3am.
What channel is it on?
BT Sport Box Office will show the bout live in Ireland for a cost of €30.
Dana White has warned UFC fans that they face prosecution for illegally streaming the event.
