Belfast's Lewis Crocker knocked out Mexico's Jose Felix in the fifth round of their welterweight contest to extend his record to 19-0 as a professional.
The 27-year-old took a few rounds to get going in the main event at the Ulster Hall in Belfast.
Crocker then produced a fine left hook in round five to stop Felix and claim his 11th victory by knockout.
But he was unable to pick up the vacant WBO Intercontinental welterweight title after he missed the weight on Friday.
The current WBA continental European champion will have his sights set on world honours in the not-so-distant future after another impressive victory.
The first and second rounds were rather uneventful, with Crocker happy to assess the Mexican, who defeated Gary Cully in his last fight, and see what he was up against.
Felix was deducted a point in the third for two low blows, but it was the fourth round where 'The Croc' really took over.
After a succession of clubbing blows, Crocker sent the 31-year-old tumbling to the canvas midway through the round.
Felix survived the onslaught, but the end was near for the Mexican.
It did eventually come in the fifth round, with the Belfast man landing a perfectly timed left hook right on the whiskers of his opponent.
Felix did well to make it back to his feet somehow, but referee Marcus McDonnell had seen enough and deemed him in no position to continue.
There were some impressive performances on the undercard too, with Lisburn's Kurt Walker moving to 10-0 after a points victory over the tough Darwing Martinez.
Limerick's Paddy Donovan secured a 10th knockout, moving to 13-0 after beating Williams Andres Herrera.
But Belfast's Tommy McCarthy suffered defeat in front of his hometown fans, losing via fourth-round stoppage to Cheavon Clarke.
