FNC 21: Martin Batur vs. Michal Andryszak

FNC 21 took place on February 15, 2025, at the Krešimir Ćosić Hall (Višnjik) in Zadar, Croatia. This event was the promotion's first major show of 2025 and drew a sold-out crowd of over 8,500 fans. The main event ended in anti-climactic fashion when local heavyweight favorite Martin Batur suffered a leg injury (specifically to his knee) early in the first round. While attempting a takedown, Batur's leg buckled, forcing an immediate stoppage at just 0:32 of Round 1. As a result, Polish veteran Michal "Longer" Andryszak was declared the winner by TKO (injury), though he immediately expressed his willingness to grant Batur a rematch once he recovered.
