Anticipation is high among UFC fans, as the big rematch between Conor McGregor and Nate Diaz takes place this Sunday morning (if you're in the UK – Saturday night for our US cousins).
McGregor faces somewhat of a challenge, fighting 25lbs over his usual featherweight division against the bigger Diaz.
But the Irishman will undoubtedly give it everything he's got following his defeat at the hands of Diaz at UFC 196.
The main card gets going at 3am UK time, and features four fights, with the McGregor Diaz bout due to start around 5am UK time Sunday morning (or thereabouts).
