Jamie Conlan picked up the vacant WBC silver international super-flyweight title via a split decision against Yader Cardoza in Belfast.
Conlan was knocked down in round eight but he recovered well to extend his professional record to 19-0 at Waterfront Hall.
The 30-year-old, who remains on course for a world title eliminator, edged the first three rounds but Cardoza worked his way into the contest in round four.
The Nicaraguan then sent Conlan crashing to the canvas after a flurry of punches in round eight which rocked the Northern Irishman.
Conlan, though, composed himself well and, despite suffering a cut above his eye, held on to claim the victory.
