Rendall Munroe (right) in action against Fabrizio Trotta on Thursday
Rendall Munroe beat Italy's Fabrizio Trotta in Dublin on Thursday for the third defence of his European super- bantamweight title.
Trotta was unable to continue after spraining his wrist as he threw a punch halfway through the fifth round.
Leicester's Munroe said: "I was too strong. He was looking for a way out."
The 28-year-old bin man is set to fight again on 27 February and is looking for a venue in his home town for his next title defence.
Trainer Jason Shinfield told BBC Radio Leicester: "The fight went absolutely to plan. We are now looking for a big venue somewhere in Leicester."
Ireland's Olympic middleweight bronze medallist Darren Sutherland made his professional debut on the same bill, stopping Georgi Iliev in round one.
Also on the same bill, Nottingham's Jason Booth defended his Commonwealth bantamweight crown when Pontefract's Sean Hughes was retired by his corner at the end of the 10th.
