Conor McGregor and Donald Cerrone meet in a huge UFC 246 main event as 'Notorious' looks to begin 2020 with a bang.
The Dubliner has not fought in 15 months - that fateful night in Las Vegas in October 2018 when he lost to Khabib Nurmagomedov and all hell broke loose in the aftermath.
A host of huge fights potentially await in 2020 - the Khabib and Nate Diaz rematches and a box office showdown with Jorge Masvidal among them.
Cerrone can wreck those plans, however, by inflicting a third consecutive loss that will raises further doubts over the future of the UFC's first ever double champion.
Here's how you can follow all the action...
