Della Maddalena claimed the UFC welterweight title in May 2025, defeating then-champion Belal Muhammad by unanimous decision at UFC 315. Over the course of his eight-fight UFC career, Della Maddalena has picked up six fight-night bonus awards.

After an unsuccessful UFC debut where he suffered a second-round submission loss to AJ Fletcher, Gorimbo went on a four-fight winning streak, beating Takashi Sato, Pete Rodriguez, Ramiz Brahimaj, and Nico Price. His only recent setback came in December at UFC 310 at the hands of veteran Vicente Luque, who submitted him in under a minute.
