There is a new main event in Las Vegas tonight. How to catch the promotion’s latest feast of MMA action this weekend.

Alex Pereira and Jiri Prochazka will go head-to-head in an unexpected rematch for the former’s UFC Light Heavyweight Championship crown when the pair meet as the new headliners of UFC 303 following the cancellation of Conor McGregor’s comeback bout with Michael Chandler.

The Notorious had been set to make his long-awaited return to the octagon at the T-Mobile Arena in Las Vegas, Nevada, United States, later this month, but the Irishman has been unable to make the fight, forcing its postponement to a later date.

This means that incumbent belt holder Pereira will face the man he saw off for the crown in the first place last November, when he defeated former champion Prochazka for the vacant title at UFC 295.

With one successful defense under his belt so far, the Brazilian – a two-weight champion during his time in UFC – will feel confident of keeping hold of the top prize, particularly against an opponent he has already defeated once before – but that is likely only to fire the Czech fighter up even more as he goes in pursuit of his rival.

So, how can you watch all the action unfold from UFC 303, and when does it take place? GOAL brings you all the details, including when and where to watch and who will fight on the bill.
