Donaire said: "It's great to be here in Belfast. Some people are writing me off as 'the old guy' but I feel I'm peaking now both physically and in terms of experience.
"Being in Belfast, the weather is cold but the welcome is warm. I've had people coming up to me - many of them who are serious Frampton fans - and welcome me to the city. I appreciate that."
Promoter Frank Warren said of the clash: "If you want to see a real fight on Saturday night, there's only one place to be. None of this celebrity in a jungle stuff - this is proper boxing."
MTK Global Professional Development Coordinator Jamie Conlan, who has already enjoyed his fair share of big nights in the city, added: "This is the biggest fight Belfast has ever seen."
