FNC 18 took place on July 13, 2024, at the Borik Hall (Dvorana Borik) in Banja Luka, Bosnia and Herzegovina. This event marked the promotion's first-ever visit to Banja Luka and drew a passionate, sold-out crowd. In the main event, the "Skull Crusher" Marko Bojković continued his undefeated streak by defeating Brazilian veteran Arlen "Benks" Ribeiro via submission (armbar) at 3:14 of the first round. Bojković’s victory was particularly satisfying as the two had been scheduled to fight two years prior before an injury delayed the matchup.
