Carl Frampton takes on Tyler McCreary in the early hours of Sunday morning.
The Jackal is a big favourite to see off the relatively unknown American in Las Vegas.
But after 11 months out of the ring can Frampton turn on the style once again and edge towards another world title shot?
Or will ring rust make it a difficult night for the 32-year-old?
We asked some other Irish boxing stars to give us their thoughts on the fight.
Here's what they had to say:
Ryan Burnett - former unified world bantamweight champion
Michael Conlan - fights in New York on December 14
Sean McComb - unbeaten super-lightweight
Tyrone McKenna - Belfast super-lightweight
Lewis Crocker - welterweight prospect
Conrad Cummings - former European champion
Tommy McCarthy - WBC International cruiserweight champion
Paddy Gallagher - Belfast welterweight
