Video: The Irish have completely taken over Las Vegas ahead of Conor McGregor fight
There are thousands of Irish MMA fans in Las Vegas right now and they are making their presence felt.
The atmosphere generated by the fans in green astounded those in attendance at the weigh-in at the MGM Grand last night.
The legendary venue also played host to a stirring rendition of the Amhrán na bhFiann from Irish supporters.
Last year, McGregor stated: "We're not here to take part... we're here to take over."
Don't believe us.... here is the evidence to show that the Chad Mendes fans will be grossly outnumbered tonight.
