We hope that there's Guinness on tap at the MGM Grand Garden Arena.
Irish MMA fans are expected to descend on the Las Vegas venue in their thousands for Conor McGregor's featherweight title bout against long-time champion Jose Aldo.
UFC 189 will feature three Irish fighters in McGregor, Cathal Pendred and Neil Seery. That's not to mention honorary Irishman Gunnar Nelson who can catapult his way into the top ten with an impressive victory over Brandon Thatch.
And Dana White has revealed that there will be more Irish voices cheering than Brazilian when the main event rolls around.
The UFC president was defending a theory from a fan about why the promotion has a back-up fighter in place in the form of Chad Mendes for the possibility that Jose Aldo's rib injury prevents him from competing.
The fight capital of the world better get ready for some renditions of
The Fields of Athenry.
