Carl Frampton will head to Las Vegas in the New Year to make the first defence of his WBA featherweight crown in a rematch with Leo Santa Cruz.
The two-weight world champion announced last week that he would face Santa Cruz again, but did not reveal any further details.
However, Frampton took to social media on Tuesday night to confirm the venue and date of their showdown.
Frampton tweeted: "It's official! The rematch vs @leosantacruz2 is set for @MGMGrand Las Vegas, January 28th. WE'RE BRINGING AN ARMY #AndStill."
The 29-year-old followed the post with a video of him singing a rendition of Elvis Presley's 'Viva Las Vegas'.
The undefeated Belfast boxer initially wanted the rematch to take place in his hometown, but acknowledged that it may have been a struggle to secure a venue big enough for the event before announcing the MGM Grand in Las Vegas.
Frampton took his first world title when he beat Spain's Kiko Martinez on a points decision in their super bantamweight IBF title clash in September 2014.
