Carl Frampton vs Nonito Donaire is the first major fight for the Belfast hero since signing with promoter Frank Warren and broadcaster BT Sport last year.
His veteran California-based Filipino opponent, 38-4 (24), has previously won world titles in four divisions – to Frampton’s two – and is renowned for his concussive power.
Frampton, 24-1 (14), will look to impress ahead of a planned huge fight at Windsor Park in the summer and the recent news that the winner will be in pole position to challenge WBO featherweight champ, Oscar Valdez, is added motivation.
The bout takes place on the 111th day of the year on Saturday April 21.
SSE Arena, Belfast.
