Belfast's Lewis Crocker knocked out Mexico's Jose Felix in the fifth round of a welterweight contest, improving his professional record to 19-0.
The 27-year-old took several rounds to qualify for the main event at Belfast's Ulster Hall.
Crocker stopped Felix with a stunning left hook in the fifth round, earning his 11th victory by knockout.
However, he missed Friday's weigh-in and was unable to win the vacant WBO Intercontinental welterweight title.
The current WBA European continental champion will have his sights set on world honors in the not-too-distant future after another impressive victory.
The first and second rounds were relatively uneventful and Crocker was happy to evaluate the Mexican, who defeated Gary Currie in his last fight, to see what he was up against.
Felix was deducted points for two low blows in the third round, but it was in the fourth round that “The Clock” really won.
After a series 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 finally happened in the fifth round, when the Belfast man timed his left hook perfectly to his opponent's beard.
Felix managed to get to his feet, but referee Marcus McDonnell had seen enough and decided he was in no condition to continue.
There were some impressive performances on the undercard as well, with Lisburn's Kurt Walker jumping to 10-0 with a points win over tough Darwin Martinez.
Limerick's Paddy Donovan defeated Williams Andres Herrera for his 10th knockout win, making him 13-0.
However, Belfast's Tommy McCarthy suffered defeat in front of his hometown fans, losing a fourth-round stoppage to Chevon Clarke.
