John Paul Hale and Eugene McKeever retained their Ulster Elite Championship titles in Belfast on Tuesday night.
Star fighter Hale beat Colm Murphy on a 4-1 decision in a superb repeat of last year's bantamweight final.
McKeever secured back-to-back welterweight titles, also by a 4-1 decision, with the Holy Family Drogheda boxer overcoming Matthew McCole.
Sionnan McKenna of Holy Family GG defeated Clodagh McComiskey in a thrilling women's flyweight contest.
The Ulster Hall hosted 11 fights but the warm-up act stole the show as three-year-old Daithi MacGabhann sent Olympic Games bronze medallist Paddy Barnes crashing to the canvas.
The three-year-old, who requires a heart transplant after being born with a congenital defect, threw a few sweet jabs before a big hook accounted for Barnes to bring up the biggest cheer of the night.
